Encyclopaedia Britannica, 11th Edition, Volume 7, Slice 4 "Coquelin" to "Costume" The gaseous form is shown conclusively by the spectroscope, but in view of the extreme delicacy of the indications with this instrument no quantitative estimate of the gas can be made. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 7 "Columbus" to "Condottiere" I found it quite easy to write notes while ascending, and even to use a pocket spectroscope at the time of the setting sun. Etna A History of the Mountain and of its Eruptions And now the mulled world outside changed again, shading from blood-red to fairy rose-color as seen through the spectroscope of hope. Pemrose Lorry, Camp Fire Girl It was all too easy for the spectroscope to overlook Flimbot, the nineteenth. Once a Greech It can be seen with the eye at the beginning or ending of a total eclipse of the sun, and with a suitable spectroscope at any time under favourable conditions. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 3 "Chitral" to "Cincinnati" Some light is thrown on this and other questions by the spectroscope. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 7 "Columbus" to "Condottiere" Examined by the spectroscope the Fraunhofer lines were extremely distinct, particularly two lines near the red end of the spectrum. Etna A History of the Mountain and of its Eruptions Savagely she applied her eye to the tall, ten-foot spectroscope rearing its brazen height from this low pedestal. 16Without, beyond the glaring white-washed laboratory, was a February world, equally white, of zero ice and snow. Pemrose Lorry, Camp Fire Girl The spectroscope camera is set up at one end of a long corridor. Astounding Stories, July, 1931 Of other metals first detected by the spectroscope mention is to be made of indium, determined by F. Reich and H.T. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 1 "Châtelet" to "Chicago" It happens that, since the spectroscope has been perfected, no comet of great brilliancy has been favourably situated for observation. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 7 "Columbus" to "Condottiere" Viewed with the spectroscope, this presents the spectrum of carbon, and generally so brilliant as to mask totally the spectra of other gases present. The Galaxy, Volume 23, No. 2, February, 1877 Through the spectroscope she saw a world in flames–blood-red. Pemrose Lorry, Camp Fire Girl Even to-day these tonal centres are still used; for they are elemental, like the primitive colors of the spectroscope. Music: An Art and a Language Closely related to the flame-colorations, we have to notice the great services rendered by the spectroscope to the detection of elements. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 1 "Châtelet" to "Chicago" The Rogans must already know it; zinc was common to Jupiter, as Earth spectroscopes had showed long since; and they had no doubt analyzed it by now. The Red Hell of Jupiter To discover by the spectroscope the smallest quantity of a gaseous or very volatile hydrocarbon, the Messrs. Negri introduce a small quantity of the gaseous mixture into a tube. The Galaxy, Volume 23, No. 2, February, 1877 With a veering laugh the weathercock was here bent forward, striving to catch some brazen glimpse of a winking profile in the polished brass of the spectroscope. Pemrose Lorry, Camp Fire Girl It works on the principle of the spectroscope with modifications. Astounding Stories of Super-Science, October, 1930 The spectroscope has played an all-important part in the characterization of the elements, which, in combination with oxygen, constitute the group of substances collectively named the “rare earths.” Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 1 "Châtelet" to "Chicago" With the spectroscope they examine the light that comes from the sun and stars and by the colors of the spectra they can tell what these far-distant bodies are made of. Common Science The spectroscope shows plenty of metals, including heavy radium deposits. The Planetoid of Peril These exist in blood and nothing but blood, so that, when the spectroscope fails, the microscope succeeds. The Harmsworth Magazine, v. 1, 1898-1899, No. 2 In another instant he was shouldering Carnes aside and staring through the spectroscope. Astounding Stories of Super-Science, October, 1930 We know from Mendeleff's table that there are a number of elements which we have not discovered as yet, and several of the ones we know were first detected by the spectroscope. Astounding Stories of Super-Science April 1930 The instrument they use to break up the light into its different colors is called a spectroscope, and the band of colors formed is called the spectrum. Common Science He would, for instance, turn his spectroscope on the sun, and not on the great ball which represents it in the mechanism, if he wanted to determine the constituents of that great luminary. Memoranda Sacra But though the spectroscope is a certain discoverer of blood, it can draw no distinction between human and animal blood. The Harmsworth Magazine, v. 1, 1898-1899, No. 2 Dr. Bird clamped the gas-detecting spectroscope on the front of his cockpit and peered through it. Astounding Stories of Super-Science, October, 1930 The famous scientist paid no attention to the interruption but bent his head lower over the spectroscope with which he was working. Astounding Stories of Super-Science April 1930 How well the spectroscope has confirmed this idea it is not necessary to say. Sir William Herschel: His Life and Works This message we are able to read, for we have begun to understand the language the stars speak to us by their light since the invention of the spectroscope. The Children's Book of Stars Reliable as are the microscope and spectroscope, the analyst always uses the third means at his disposal—the chemical test. The Harmsworth Magazine, v. 1, 1898-1899, No. 2 The pilot executed the maneuver and Dr. Bird peered over the edge of the plane and directed the spectroscope toward the ground. Astounding Stories of Super-Science, October, 1930 I thought that I could catch traces of Von Beyer's lines in my spectroscope, and I think now that it is due to a trace of lunium in the cadmium plating of the barrels. Astounding Stories of Super-Science April 1930 But the spectroscope shows that the star is double and that its components are in rapid revolution around one another, completing their orbital swing in the astonishingly short period of four days! Pleasures of the telescope An Illustrated Guide for Amateur Astronomers and a Popular Description of the Chief Wonders of the Heavens for General Readers The spectroscope tells us that these colours indicate different stages in the development of the stars, or differences of constitution—that is to say, in the elements of which they are made. The Children's Book of Stars Light is the channel, the messenger of information; our eyes, aided by telescopes, spectroscopes, and many other "scopes" that may yet be invented, are the means by which we read the information that light brings. Pioneers of Science As he rose he saw that Dr. Bird was already on his feet and was eagerly searching the ground with the spectroscope which he had brought with him in the jump. Astounding Stories of Super-Science, October, 1930 "I forgot to tell you that this is a fluoroscopic spectroscope designed for the detection of ultra-violet lines," replied Dr. Bird. Astounding Stories of Super-Science April 1930 A beautiful sparkling effect which the nebula presents was once thought to be an indication that it was really composed of a circle of stars, but the spectroscope shows that its constitution is gaseous. Pleasures of the telescope An Illustrated Guide for Amateur Astronomers and a Popular Description of the Chief Wonders of the Heavens for General Readers To turn from fancy to facts, we find that telescope and spectroscope have supplied us with quite enough matter for wonder without calling upon imagination. The Children's Book of Stars This brighter star is found by means of the spectroscope to be actually composed of three stars so very close together that they cannot be seen separately even with a telescope.

Astounding Stories of Super-Science, October, 1930 From the instrument case he had brought he took out a spectroscope. Astounding Stories of Super-Science April 1930 Huggins and Miller eagerly studied the star with the spectroscope, and their results were received with deepest interest. Pleasures of the telescope An Illustrated Guide for Amateur Astronomers and a Popular Description of the Chief Wonders of the Heavens for General Readers Now, the spectroscope has changed all this, and we can tell quite as certainly if a star is coming toward us as we can if it moves to one side. The Children's Book of Stars The spectroscope shows that the brighter of these stars is again a binary system of two huge suns, the components revolving around each other in a period of about twenty days. Astronomy of To-day A Popular Introduction in Non-Technical Language What spectroscope is to horoscope, destiny is to chance. The Dark Star His sagacious conclusion with regard to the non-stellar nature of this nebulous matter was afterwards confirmed by the spectroscope; for at that time it was believed that even the faintest nebul� were irresolvable star clusters. The Astronomy of Milton's 'Paradise Lost' The spectroscope, in fact, makes known to us the presence of many stars which no telescope could reveal. The Beauties of Nature and the Wonders of the World We Live In Hence, prominences formed by the spectroscope out of these particular qualities of violet light, can be photographed entire and at once, for the simple reason that they are projected upon a naturally darkened background. A Popular History of Astronomy During the Nineteenth Century Fourth Edition Pickering, the first of the kind by means of the spectroscope, was announced in 1889 from the Harvard Observatory in the United States. Astronomy of To-day A Popular Introduction in Non-Technical Language First, the spectroscope showed lines of reflected light passing through oxygen and hydrogen, water vapor and carbon dioxide. Empire Its content was more mysterious, more inaccessible than that of the remotest star which yields the secret of its substance to the spectroscope of the astronomer. The Invader A Novel The spectroscope showed that it was decidedly auroral, but as the aurora was seen on the dark disc of the moon it must have been due to the earth's atmosphere. Personal Recollections, from Early Life to Old Age, of Mary Somerville Now the spectroscope offers the means of indefinitely weakening atmospheric glare by diffusing a constant amount of it over an area widened ad libitum. A Popular History of Astronomy During the Nineteenth Century Fourth Edition If, then, we observe this yellow flame with the spectroscope, we find that its spectrum consists almost entirely of two bright yellow transverse lines. Astronomy of To-day A Popular Introduction in Non-Technical Language The flames, as examined by the spectroscope, appear to be largely composed of hydrogen gas; and no doubt many other gases—some quite unknown to us—enter into their composition. To Mars via The Moon An Astronomical Story The spectroscope may be used with a grating or a 60 degree prism, and for this purpose has openings for the telescopes at the proper angles. Astronomical Instruments and Accessories There are indications of the existence of an atmosphere around Venus, and the evidence of the spectroscope shows that water vapour is there present. The Story of the Heavens Yet here the verdict of the spectroscope is adverse and irreversible. A Popular History of Astronomy During the Nineteenth Century Fourth Edition The spectroscope supplies us with even more information.

Astronomical Instruments and Accessories The spectroscope tells us that a remarkable atmosphere, containing apparently some gases foreign to our own, deeply envelops Uranus. The Story of the Heavens As to the movements of the constipated vapours forming spots, the spectroscope is also competent to supply information. A Popular History of Astronomy During the Nineteenth Century Fourth Edition Thus the spectroscope enables us to find out the composition of substances when they are reduced to vapour in the laboratory. Astronomy of To-day A Popular Introduction in Non-Technical Language The light of the sun, sifted out by the spectroscope, shows all the colours but not all the tints of the rainbow. Myths and Marvels of Astronomy The spectroscope also shows lines of absorption, which proves that Mercury has a gaseous envelope thicker than ours. The Fire People Some of the more recently discovered planetary nebulæ are extremely small, and they have indeed only been distinguished from small stars by the spectroscope. The Story of the Heavens From these hints, supplemented by his own diligent observations and sagacious reasonings, Herschel elaborated a scheme of solar constitution which held its ground until the physics of the sun were revolutionised by the spectroscope. A Popular History of Astronomy During the Nineteenth Century Fourth Edition With regard to its chemical composition, the spectroscope shows us that thirty-nine of the elements which are found upon our earth are also to be found in the sun.

Astronomy for Amateurs After his return from his visit to Ruhleben Camp he mentioned in a lecture that some of the science students interned there were very anxious to obtain the use of a spectroscope. The Better Germany in War Time Being some Facts towards Fellowship The spectroscope has given us the means of studying other interesting features on the sun, which are so faint that in the full blaze of sunlight they cannot be readily observed with a mere telescope. The Story of the Heavens The excursions of opinion on the point were abruptly restricted and defined by the application to them of the spectroscope. A Popular History of Astronomy During the Nineteenth Century Fourth Edition Slipher, finds with the spectroscope faint traces of water vapour in the Martian atmosphere. Astronomy of To-day A Popular Introduction in Non-Technical Language Dr. Huggins in 1864 first made the discovery of the existence of Hydrogen in certain nebulae by means of the spectroscope, which distinctly revealed certain lines that proved the existence of Hydrogen in the nebulae. Aether and Gravitation A spectroscope I believe, is an instrument which takes a ray of light and proceeds to spread it abroad. The Better Germany in War Time Being some Facts towards Fellowship It remains to be added that in the highest class of spectroscopes the prisms are replaced by ruled gratings from which the light is reflected. The Story of the Heavens The spectroscope, however, here as elsewhere, can supplement the telescope; and what it has to tell, it tells at once, without the necessity of waiting on time to ripen results. A Popular History of Astronomy During the Nineteenth Century Fourth Edition The spectroscope tells us that it is a mass of glowing gas. Astronomy of To-day A Popular Introduction in Non-Technical Language So that spectroscopic results seem to confirm this hypothesis, as the pure Aether that would surround every star, or multiples of stars, would certainly not reveal any dark lines by means of the spectroscope. Aether and Gravitation A spectroscope, I believe, is an instrument which takes a ray of light and proceeds to spread it abroad. The Better Germany in War Time Being some Facts towards Fellowship Several observers, armed with spectroscopes, were on the look-out for the prominences, and were able to announce that their spectrum consisted of detached bright lines, thus demonstrating that these objects were masses of glowing gas. The Story of the Heavens The telescope has been supplemented by the spectroscope and the photographic camera. A Popular History of Astronomy During the Nineteenth Century Fourth Edition The method of detecting binary stars by means of the spectroscope is an application of Doppler's principle.

The Better Germany in War Time Being some Facts towards Fellowship We have spoken of the spectroscope as depending upon the action of glass prisms. The Story of the Heavens It was, nevertheless, negatived by the first application of the spectroscope to these bodies. A Popular History of Astronomy During the Nineteenth Century Fourth Edition Now there are certain stars which always appear single even in the largest telescopes, but when the spectroscope is directed to them a spectrum with two sets of lines is seen. Astronomy of To-day A Popular Introduction in Non-Technical Language Engaging his tender "hopeful" in the wonders of astronomy—"Men have learned the distances of the stars," observed the father; "and, with their spectroscopes, found out what they are made of." Children's Rhymes, Children's Games, Children's Songs, Children's Stories A Book for Bairns and Big Folk The spectroscope story is a particularly good example of the way reprisals of good work out. The Better Germany in War Time Being some Facts towards Fellowship We have frequently in the previous chapters had occasion to refer to the revelations of the spectroscope, which form an important chapter in the history of modern science. The Story of the Heavens Several diversely-coloured images of them are formed in the spectroscope; each may be seen under a crimson, a yellow, a green, and a deep blue aspect. A Popular History of Astronomy During the Nineteenth Century Fourth Edition After the extraordinary revelations of the spectroscope—nay, after the astounding discovery of Röntgen—the word impossible should be cast aside, and inconceivability cease to be regarded as any criterion. Astronomy of To-day A Popular Introduction in Non-Technical Language The spectroscope was largely brought into play with the immediate result of showing that the Corona was to be deemed a sort of atmosphere of the Sun, not self-luminous, but shining by reflected light. The Story of Eclipses The spectroscope game was started by Bishop Bury. The Better Germany in War Time Being some Facts towards Fellowship In the present chapter we propose to give an account of what the spectroscope tells us about the physical constitution of the fixed stars. The Story of the Heavens Nevertheless, the spectroscope gives little countenance to the supposition of any considerable permanent light-emission. A Popular History of Astronomy During the Nineteenth Century Fourth Edition It hadn't been leaking out just before he opened the door in the firewall, because Willows would certainly have noticed the bright mercury line when he checked with the spectroscope. The Bramble Bush The spectroscope and the camera are steadily ousting the simple telescope of every sort and unassisted eye observations from solar eclipse work. The Story of Eclipses Willis put the spectroscope away, estimated for himself, and then checked with the dial that indicated the brightness of the still point-sized star. A Matter of Importance This has actually been discovered by means of the spectroscope. The Story of the Heavens The whole range of Fraunhofer lines is visible when the light from a spot is examined with the spectroscope; but relatively few are widened.

The spectroscope gives you the limitation which makes the colours perceptible to your human eyes. Seen and Unseen Seaton picked out a distant star in their course and observed it through the spectroscope. The Skylark of Space But the spectroscope is adequate to the task, and it renders its analysis with an amount of evidence that is absolutely convincing. The Story of the Heavens Yet these felicities of explanation must not make us forget that the chemical composition attributed to the first type of cometary trains has, so far, received no countenance from the spectroscope. A Popular History of Astronomy During the Nineteenth Century Fourth Edition Each of the elements has a characteristic spectrum, and the presence of the metals can easily be detected by the spectroscope. An Elementary Study of Chemistry The Ray may be split up into sequence, but the colours belong to it all the same, and by a perfectly seeing eye would be known and recognised without the help of the spectroscope. Seen and Unseen Almost in their line of flight they saw a close cluster of stars, each emitting a peculiar greenish light which, in the spectroscope, revealed a blaze of copper lines. The Skylark of Space What a fund of information our modern spectroscopes and other instruments would supply us with if so magnificent a star were to burst out in these modern days! The Story of the Heavens It needs a powerfully dispersive spectroscope to show line-displacements of the minute order in question; and powerful dispersion involves a strictly proportionate enfeeblement of light. A Popular History of Astronomy During the Nineteenth Century Fourth Edition Through the agency of the spectroscope it had been known to exist in the sun long before its presence on the earth had been demonstrated,—a fact suggested by the name helium, signifying the sun. An Elementary Study of Chemistry Logically, of course, Holiness can never be absent, since it is the cause of all Existence; but it is apparently absent, and this apparent absence, this separation, this evil in fact, acts as a spectroscope. Seen and Unseen I know very little of astronomy," he said to Seaton, "but with our telescope, spectroscope, and other instruments, we should be able to take some data that will be of interest to astronomers. The Skylark of Space But what the telescope could not show, the spectroscope has lately demonstrated in a most effective and interesting manner. The Story of the Heavens George reminded the Professor that he had not yet explained to them what the spectroscope was, and its uses.

Recreations in Astronomy With Directions for Practical Experiments and Telescopic Work They can be observed, however, by the spectroscope any day, and they are visible to us for a very short time during an eclipse of the sun. The Outline of Science, Vol. 1 (of 4) A Plain Story Simply Told We know how Sir William Ramsay and Dr. Travers first observed by means of the spectroscope the characteristics of the companions of argon in the least volatile part of the atmosphere. The New Physics and Its Evolution The spectroscope is the improved instrument by which the diffracting prism is best employed in producing the spectrum. Notable Events of the Nineteenth Century Great Deeds of Men and Nations and the Progress of the World Was there ever a more fertile period than the generation which succeeded Darwin's achievement in biology and Bunsen's and Kirchhoff's with the spectroscope? Recent Developments in European Thought The invention of the telescope constituted one era in Astronomy; its perfection in our day, another; and the discoveries of the spectroscope a third—no less important than either of the others. Recreations in Astronomy With Directions for Practical Experiments and Telescopic Work The instrument used for this purpose is the spectroscope; and before proceeding to deal further with the sun and the source of its energy it will be better to describe this instrument. The Outline of Science, Vol. 1 (of 4) A Plain Story Simply Told The spectroscope was formed entirely of fluor-spar, and a vacuum had been created in it, for these radiations are extremely absorbable by the air. The New Physics and Its Evolution Could the spectroscope be used in determining also the character of the materials in those orbs that we see shining in the depths of space? Notable Events of the Nineteenth Century Great Deeds of Men and Nations and the Progress of the World Besides its more direct use in the chemical analysis of the heavenly bodies, the spectroscope had given to us a great and unexpected power of advance along the lines of the older astronomy. Scientific American Supplement No. 819, September 12, 1891 As we can let only a small beam of light pass through the prism, in studying celestial objects with a telescope and spectroscope we must, in Fig. Recreations in Astronomy With Directions for Practical Experiments and Telescopic Work The spectroscope is an instrument for analysing light.

A Wonderful Night; An Interpretation Of Christmas In the future a higher value might, indeed, be placed upon this indirect use of the spectroscope than upon its chemical revelations. Scientific American Supplement No. 819, September 12, 1891 Within a very few years this wonderful instrument, the spectroscope, has made amazing discoveries. Recreations in Astronomy With Directions for Practical Experiments and Telescopic Work We have already learnt something of the principles of the spectroscope, the instrument which, by making it possible to learn the actual constitution of the stars, has added a vast new domain to astronomy. The Outline of Science, Vol. 1 (of 4) A Plain Story Simply Told Verily and indeed, no microscopes, spectroscopes, telescopes, photometers, or other physical apparatuses can ever be focused on either the macro-or micro-cosmical highest principles, nor will the mayavirupa of either yield its mystery to physical inquiry. Five Years of Theosophy I don't allude to the wonderful revelations of the spectroscope almost passing belief, but the new departure in the useful art of house-painting. Homes and How to Make Them Thus we have from the spectroscope a complete account of what has taken place to produce the original colour and its changes. Six Lectures on Light Delivered In The United States In 1872-1873 But the spectroscope, seeing not merely form but substance also, shows that some of them are not stars in any sense, but masses of glowing gas. Recreations in Astronomy With Directions for Practical Experiments and Telescopic Work We saw in a previous chapter how the spectroscope splits up light-waves into their colours. The Outline of Science, Vol. 1 (of 4) A Plain Story Simply Told We have only to compare the telescope of Galileo, the prism of Newton, the pile of Volta, and what was done with them, to the marvelous work of the telescope, spectroscope, and dynamo of to-day. Scientific American Supplement, No. 484, April 11, 1885 So saying, he attached to the telescope a magnificent spectroscope, which he employed in his researches on the nebulæ, and renewed his observation. A Trip to Venus At this stage each part of the spectrum has its own proportional intensity, and the whole produces the colourless image seen without the spectroscope. Six Lectures on Light Delivered In The United States In 1872-1873 The spectroscope showed it to be a star in the usual condition; but through the usual colored spectrum, crossed with bright lines, shone four bright lines, two of which indicated glowing hydrogen.

Scientific American Supplement, No. 821, September 26, 1891 "I confess it's a mystery to me," he answered, pondering deeply; and then, as if struck by a sudden thought, he added: "I wonder if it's any good trying the spectroscope on it?" A Trip to Venus Newton connected the most distant points of the universe by the one principle of gravitation: the spectroscope unites them by identity of structure and composition. Lippincott's Magazine of Popular Literature and Science Volume 17, No. 097, January, 1876 But the spectroscope shows another state of things: it reveals in some of these comets an incandescent gas—usually some of the combinations of carbon. Recreations in Astronomy With Directions for Practical Experiments and Telescopic Work The umbrella is examined under severe test conditions: it is weighed in a vacuum, and placed under the spectroscope. Twenty-One Days in India; and, the Teapot Series The remarkable discoveries that the spectroscope has enabled, and the facts learned from the physical history of comets and meteorites, can do no more than make what is known as the "nebular hypothesis" highly probable. Creation and Its Records I demanded, looking into the spectroscope, where I could distinguish several faint streaks of coloured light on a darker background. A Trip to Venus Startling indeed it is to the scientist to be told that an artificial dream-world of the mathematician is more real than that he sees with his galvanometers, ultra-microscopes, and spectroscopes. Architecture and Democracy They can be seen at any time by the use of a proper telescope with a spectroscope attached. Recreations in Astronomy With Directions for Practical Experiments and Telescopic Work Near him as he spoke, on a table were the wand, the rings, the vials, above all a spectroscope with its prisms, the apparatus with which the magician solved the universe. The Last Leaf Observations, during Seventy-Five Years, of Men and Events in America and Europe "The fact revealed by the spectroscope," says the writer, "that the physical elements of the earth exist also in the stars, supports the faith that a moral nature like our own inhabits the universe." Composition-Rhetoric You know that we can tell the nature of a substance that is burning by splitting up the light which comes from it in the prism of a spectroscope. A Trip to Venus Her young voice haunts my eager ear; Her hair in the candle-light Still seems an aureole,—a tear Is my spectroscope to-night. When hearts are trumps Then he replaced one of the objectives by a spectroscopic attachment, and having placed the little lamp close to the microscope mirror, adjusted the spectroscope. The Red Thumb Mark But we find suggestions from the spectrum and the spectroscope which may be worth our heeding. Choice Specimens of American Literature, and Literary Reader Being Selections from the Chief American Writers The application of the spectroscope has advanced our knowledge of the subject by leaps and bounds. Popular Science Monthly Oct, Nov, Dec, 1915 — Volume 86 With these words he removed the spectroscope from the telescope, and gazed anxiously at the planet "The light is gone," he continued, after a minute. A Trip to Venus The spectroscope shows that they lose practically all the slower vibrations we call red and infra-red, while the extremely rapid vibrations we call the violet and ultra-violet are accelerated and altered. The Moon Pool He had another smaller telescope, made by himself, and had a spectroscope in process of making. Men of Invention and Industry They may be discovered with the spectroscope on any clear day. The Gutenberg Webster's Unabridged Dictionary Section P and Q When we apply the spectroscope to celestial objects we find apparently an endless variety of spectra. Popular Science Monthly Oct, Nov, Dec, 1915 — Volume 86 The telescope has banished Phoebus and Diana from our literature, and the spectroscope has vulgarised the stars.

Men of Invention and Industry And now the spectroscope was turned upon the nebula, and many of them were found to be gaseous. History of the Warfare of Science with Theology in Christendom The velocities of the Orion nebula, the Trifid nebula, the Carina nebula, and of several other irregular nebulae, have been measured with the spectroscope. Popular Science Monthly Oct, Nov, Dec, 1915 — Volume 86 It had occurred towards midnight of the twelfth; and the spectroscope, to which he had at once resorted, indicated a mass of flaming gas, chiefly hydrogen, moving with an enormous velocity towards this earth. The War of the Worlds I know it because I have demonstrated with my new spectroscope, which analyzes extra-visual rays, that all those dark nebulae that were photographed in the Milky Way years ago are composed of watery vapor. The Second Deluge Whichever of our modern discoveries we may consider to be the most startling and important, there can I think be no doubt that the most beautiful is that of the spectroscope. Scientific American Supplement, No. 417, December 29, 1883 Now that I have learned that it was a spectroscope, he is not only cleared of any suspicion of insanity, but has rendered a great service to science. Plays: the Father; Countess Julie; the Outlaw; the Stronger These have been memorized by chemists, so that when an expert having a spectroscope sees anything burn he can tell what it is as well as read a printed page. Scientific American Supplement, No. 288, July 9, 1881 Neptune is a very difficult object for the spectroscope. History of Astronomy To work out the idea, he built an observatory, set up a laboratory, invented instruments, including his strange spectroscope, which was scoffed at by the scientific world. The Second Deluge The anticipation, it is needless to say, was verified, and the spectroscope, though now superseded, had for a time its place among the regular appliances necessary for the carrying on of the Bessemer process. Scientific American Supplement, No. 417, December 29, 1883 Ah, dear brethren! men are telling us now that there is no connection between earth and heaven except such as telescopes and spectroscopes can make out.

Our Hundred Days in Europe That is a question which cannot be answered by means of the vacuum tube or the spectroscope. The Creative Process in the Individual Another discovery was made with the spectroscope; thus, if a boat moves up a river, it will meet more waves than will strike it if going down stream. Scientific American Supplement, No. 288, July 9, 1881 Hence arose the branch of astronomy called astronomical physics, a science which claims a large portion of the work of the telescope, spectroscope, and photography. History of Astronomy It does the same thing for cool, nonglowing matter that the spectroscope does when it discloses the kinds of atoms that make the stars. Autobiography of a Yogi Tut, the silly being—he should have known from the body's response to the spectroscope that its condition was too friable to resist our atmosphere. The Lord of the Sea The discovery of the radial component in the movements of the stars is due to the spectroscope. Curiosities of the Sky At the eye end of the telescope is attached the spectroscope and the micrometer, and the whole set of instruments so adjusted that just the edge of the sun is seen, making a half spectrum. Scientific American Supplement, No. 288, July 9, 1881 The spectroscope has shown that these have also often the same velocity in the line of sight. History of Astronomy As far as physical conditions are concerned, there are suns similar to our own, as revealed by the spectroscope, and which have the same eruptive energy. Marvels of Modern Science The spectroscope has plainly shown that there's water vapor in what little air there is. The Lord of Death and the Queen of Life The quiescent prominences, whose elevation is often from forty thousand to sixty thousand miles, consist, as the spectroscope shows, mainly of hydrogen and helium. Curiosities of the Sky Then was devised the spectroscope, and with it men audaciously questioned nature in her most secluded recesses. Scientific American Supplement, No. 288, July 9, 1881 In this way the spectroscope has confirmed generally Herschel’s view of the direction, and makes the velocity eleven miles a second, or nearly four astronomical units a year. History of Astronomy The spectroscope has had a wonderful part in astronomical research. Marvels of Modern Science Once we realize this, our judgment of all that our terrestrially devised optical instruments, such as the telescope and spectroscope, tell us about the nature of the sun and its surroundings, will change accordingly. Man or Matter The possession of the spectroscope has enabled astronomers during later years to study the chemical composition of comets by analyzing their light. Curiosities of the Sky But it bears no comparison to the delicacy of these defraction spectroscopes. Gold of the Gods When the spectroscope was first applied to finding the composition of the heavenly bodies, there was a great desire to find out what comets are made of. History of Astronomy The spectroscope also makes it possible to measure the velocities of objects which are approaching or receding from us. Marvels of Modern Science What we observe, when we study the sun through a spectroscope, is not the sun itself, but the conditions obtaining in this border-region, where imponderable substance enters the earth-realm. Man or Matter The prominences, however, although they were discovered during an eclipse, can now, with the aid of the spectroscope, be seen at any time. Curiosities of the Sky Here that great discovery, the spectroscope, comes to our aid. Ragnarok : the Age of Fire and Gravel Meanwhile the accumulation of facts has been prodigious, and the revelations of the telescope and spectroscope entrancing. History of Astronomy Before him was his new spectroscope, and I could see that now he was satisfied with what the uncannily delicate light-detective had told him. The Treasure-Train That," he explained, "is a spectroscope, and those are the lines of the absorption spectrum. The Dream Doctor Free oxygen cannot be in existence in the sun or in any celestial object in which the spectroscope indicates the existence of incandescent hydrogen. Story of Creation as Told By Theology and By Science Is it an outcome of that pure carbon which the spectroscope has revealed to us as burning in some of the comets? Ragnarok : the Age of Fire and Gravel A vast number of facts have been added to our knowledge about the sun by photography and the spectroscope. History of Astronomy Equipped with hammer, chisel, microscope, spectroscope and crucibles, he essayed the solution, undismayed by memories of his classics, of Sisyphus and Tantalus; seeing only the nodding poppies, the gilded primroses of his dancing goddess. At the Mercy of Tiberius The applicability of the spectroscope to the differentiation of various substances is too well known to need explanation. The Dream Doctor This is the region which till 1868 could be seen only during total eclipses, but can now be watched at all times by means of the spectroscope. Story of Creation as Told By Theology and By Science The two comets move together, like Biela's two fragments; and they give out poison--the carbureted-hydrogen gas revealed by the spectroscope. Ragnarok : the Age of Fire and Gravel Now the spectroscope enables the motion of stars to be detected at a single observation, but only that part of the motion that is in the line of sight. History of Astronomy The spectroscope, if we interpret its indications in the usual way, tells us that a comet is simply a mass of hydrocarbon vapor, shining by its own light. Side-Lights on Astronomy and Kindred Fields of Popular Science My spectroscope tells me that that, too, is blood. The Dream Doctor The spectroscope has not yet rendered this visible at all times, and consequently we are dependent upon the information to be obtained during the few minutes of total eclipses, when alone it is visible. Story of Creation as Told By Theology and By Science "But, after all," he said at last, with an awkward movement towards his spectroscope, "that does signify something." In the Days of the Comet At the other end of the spectroscope is the photographic plate. History of Astronomy A corresponding similarity is found in the physical constitution of the stars as brought out by the spectroscope. Side-Lights on Astronomy and Kindred Fields of Popular Science In cases of poisoning by these substances, the spectroscope often has obvious advantages over chemical methods, for minute amounts will produce a well-defined spectrum. The Dream Doctor Twenty years ago the spectroscope was a thing undreamt of—now astronomers reckon it as of equal value with the telescope, while chemists find it indispensable to their researches. Story of Creation as Told By Theology and By Science Parload stood listening, half turned towards the sky with the tips of his fingers on his spectroscope. In the Days of the Comet The spectroscope has revealed the fact that, broadly speaking, the sun is composed of the same materials as the earth. History of Astronomy But when their light is analyzed by the spectroscope, it is found that scarcely any two are exactly alike. Side-Lights on Astronomy and Kindred Fields of Popular Science Before I answer that question, what else does the spectroscope show? The Dream Doctor But here again the spectroscope comes to our aid. Story of Creation as Told By Theology and By Science And Parload had spent two hoarded pounds in buying himself a spectroscope, so that he could see for himself, night after night, that mysterious, that stimulating line—the unknown line in the green. In the Days of the Comet This work aims to explain the most practical and modern methods of research, and to state our present knowledge of the constitution, physical condition alld motions of the heavenly bodies, as revealed by the spectroscope. An Introduction to Chemical Science The spectroscope shows that, so far as the chemical elements go, other worlds are composed of the same elements as ours. Side-Lights on Astronomy and Kindred Fields of Popular Science If the poisons of the embalming fluid had not been injected, he had now clear proof regarding anything his spectroscope discovered. The Dream Doctor He was as simple as sunlight, and to resolve his intellect into seven colours would want the most ingenious spectroscope. Stories by English Authors: The Orient (Selected by Scribners) It was found, for example, that the spectroscope could detect the presence of a quantity of sodium so infinitesimal as the one two-hundred-thousandth of a grain. A History of Science — Volume 4 Thus the spectroscope, which deals only with light, makes paradoxical excursions into the realm of the invisible. A History of Science — Volume 3 When, forty years ago, the spectroscope was applied to analyze the light coming from the stars, a field was opened not less fruitful than that which the telescope made known to Galileo. Side-Lights on Astronomy and Kindred Fields of Popular Science The spectroscope 'spots' the substance, to use a police idiom, the moment the case is turned over to it. The Dream Doctor To have predicated the sun as a great molten mass of iron was indeed a wonderful anticipation of the results of the modern spectroscope. A History of Science — Volume 1 The value of this method of observation was recognized at once, and, as soon as the spectroscope was perfected, the photographic method, in conjunction with its use, became invaluable to the chemist. A History of Science — Volume 4 But the spectroscope is not alone in this audacious assault upon the strongholds of nature. A History of Science — Volume 3 A new instrument, the spectroscope, has been developed, the extent of whose revelations we are just beginning to learn, although it has been more than thirty years in use. Side-Lights on Astronomy and Kindred Fields of Popular Science The wire contains thallium and helium as the spectroscope shows; but its awful radioactivity and deadly emanation has yet to be explained. The Grey Room Moreover, the stars are shown by the spectroscope to consist of chemical elements identical with those which are found in the solar system. The Unseen World and Other Essays But what was even more important, the spectroscope put no limit upon the distance of location of the substance it tested, provided only that sufficient light came from it. A History of Science — Volume 4 In 1859 the spectroscope came upon the scene, perfected by Kirchhoff and Bunsen, along lines pointed out by Fraunhofer almost half a century before. A History of Science — Volume 3 The instrument with which this was first done was the spectroscope; it is now replaced with another of the same general kind, called the spectrograph.

History of the Conflict Between Religion and Science To render the utility of the spectroscope complete, however, it was necessary to link with it another new chemical agency—namely, photography. A History of Science — Volume 4 Very soon eager astronomers all over the world were putting the spectroscope to the test. A History of Science — Volume 3 If I apply this title it is because that branch of the science to which the spectroscope has given birth is often called the new astronomy. Side-Lights on Astronomy and Kindred Fields of Popular Science Yet the significance of the three predominating colours—blue-white, yellow, and red—has been sustained by the spectroscope. The Story of Evolution The finest instrument of these discoveries is metaphor, the spectroscope of letters. Style For once even that mystery-solver the spectroscope has been baffled, for the line it sifts from the aurora is not matched by that of any recognized substance. A History of Science — Volume 3 Since then the spectroscope has added its confirmatory evidence as to the identity of meteorite and shooting-star, and, moreover, has linked these atmospheric meteors with such distant cosmic residents as comets and nebulae. A History of Science — Volume 3 I can only mention among the problems of the spectroscope the elegant and remarkable solution of the mystery surrounding the rings of Saturn, which has been effected by Keeler at Allegheny. Side-Lights on Astronomy and Kindred Fields of Popular Science And the spectroscope gives us good ground to conclude that the stars are cooling. The Story of Evolution It was suggested at the time that the bursting of a star may merely have lit up a previously dark nebula, but the spectroscope does not support this. The Story of Evolution The spectroscope and telescopic photography, which are far more important than the visual telescope, are comparatively recent, and the field to be explored is enormous. The Story of Evolution Since then the existence of other and quite invisible star companions has been proved incontestably, not merely by renewed telescopic observations, but by the curious testimony of the ubiquitous spectroscope. A History of Science — Volume 3 It must be confessed, however, that the spectroscope has rather increased than diminished the mystery which, in some respects, surrounds the constitution of these bodies. Side-Lights on Astronomy and Kindred Fields of Popular Science Nearly a hundred other nebulae are known, by the spectroscope, to be clouds of luminous gas. The Story of Evolution The spectroscope shows that these knots are condensing masses of white-hot liquid or solid matter. The Story of Evolution |
