A Text-Book of Precious Stones for Jewelers and the Gem-Loving Public And she has tourmaline eyes, with reddish hazel specks in an iris of opaque blue, and small white teeth and lips with a telltale curve of wilfulness about them. The Prairie Mother Causing the crystal of tourmaline to revolve round the tube, with its axis perpendicular to the illuminating beam, the quantity of light that reached the eye was in all its positions a maximum. Fragments of science, V. 1-2 I paused, and Margot turned her tourmaline eyes full on me. War and the Weird But as the tourmaline cools yet further, though but a fraction of a degree, the magnetic properties change; the positive pole becomes the negative, the negative having changed to the positive. The Chemistry, Properties and Tests of Precious Stones These double images might have been produced by tourmaline as well as by emerald. A Text-Book of Precious Stones for Jewelers and the Gem-Loving Public The ancients also described what was probably tourmaline, a mineral which has the same qualities.

A Text-Book of Precious Stones for Jewelers and the Gem-Loving Public One or two minute crystals showed a green colour, and might be tourmaline or emerald; but perhaps it was only a surface-colour caused by the presence of copper. To The Gold Coast for Gold, Vol. II A Personal Narrative It was made up of quartz, feldspar, and mica, and there were also some isolated specimens of pyrites, hornblend, tourmaline, and serpentine. Transactions of the American Society of Civil Engineers, vol. LXVIII, Sept. 1910 The New York Tunnel Extension of the Pennsylvania Railroad The Terminal Station - West In this manner the conditions in the complex molecule of biotite, tourmaline, etc., may be quite as effective in preventing initial recombination as the most effective electric force we could apply. The Birth-Time of the World and Other Scientific Essays The tourmaline is a most complex substance; almost every stone obtained has a different composition, some varying but slightly, with mere traces of certain constituents which other stones possess in a perceptible degree. The Chemistry, Properties and Tests of Precious Stones They consisted mainly of minute jagged cracks of the character peculiar to brittle materials such as both emerald and tourmaline. A Text-Book of Precious Stones for Jewelers and the Gem-Loving Public And perhaps another in gold with the sacred monogram wrought on the cup in jacinths and orange tourmalines. The Altar Steps I was in the first row, and because I had a necklace of pink tourmaline, he quickly saw that I was the daughter of a chief.

The Port of Adventure Their robes and rings were mine to draw from shimmering trays — Brocades and broidered silks, topaz and tourmaline — Their turban-cloths to wind in proud capricious ways, And fasten plumes and pearls and pendent sapphires in. Poems Let us take, as an example, the crystal of tourmaline, with which we are now so familiar. Six Lectures on Light Delivered In The United States In 1872-1873 Sometimes their lateral faces are longitudinally striated, and as deeply as the tourmaline, so that the edges of the prism are rendered indistinct. Lippincott's Magazine of Popular Literature and Science Volume 11, No. 27, June, 1873 The various tourmalines very closely resemble each other in their properties, the slight differences corresponding to differences in composition do not alter the general nature of the material.

Zuleika Dobson, or, an Oxford love story Mr. Hamlin became interested in gems because of his accidental discovery of some of the fine tourmalines of Maine. A Text-Book of Precious Stones for Jewelers and the Gem-Loving Public Placing the tourmaline in front of the aperture, two images of the crystal will also be obtained; but now let us reason out beforehand what is to be expected from this experiment. Six Lectures on Light Delivered In The United States In 1872-1873 A very fine Maine tourmaline might approach this stone in color, so it became necessary to consider this possibility. A Text-Book of Precious Stones for Jewelers and the Gem-Loving Public Gem tourmaline comes from Ceylon, from Madagascar, from the Ural Mountains, from Brazil, from Maine, from Connecticut, and from California. A Text-Book of Precious Stones for Jewelers and the Gem-Loving Public The sharp jagged flaws and cracks that so often appear in emerald are likely to appear also in tourmaline as both are brittle materials. A Text-Book of Precious Stones for Jewelers and the Gem-Loving Public Brown tourmaline is sometimes very pleasing in color. A Text-Book of Precious Stones for Jewelers and the Gem-Loving Public The light emergent from the tourmaline is polarized. Six Lectures on Light Delivered In The United States In 1872-1873 For a long time investigators were compelled to employ plates of tourmaline for this purpose, and the progress they made with so defective a means of inquiry is astonishing. Six Lectures on Light Delivered In The United States In 1872-1873 Brazilian tourmalines are usually green, but sometimes red. A Text-Book of Precious Stones for Jewelers and the Gem-Loving Public If, at the sacrifice of half the light, we could abolish one of these, the other would place at our disposal a beam of polarized light, incomparably stronger than any attainable from tourmaline. Six Lectures on Light Delivered In The United States In 1872-1873 But, prior to this, it will be desirable to establish still further the analogy between the action of the prisms and that of the two plates of tourmaline. Six Lectures on Light Delivered In The United States In 1872-1873 Hence we may infer that one image of the tourmaline will show the ordinary green light of the crystal, while the other image will be black. Six Lectures on Light Delivered In The United States In 1872-1873 Hence a plate of tourmaline, with its axis parallel to the beam, stops the light, and with the axis perpendicular to the beam transmits the light. Six Lectures on Light Delivered In The United States In 1872-1873 Would it not be fitting on account of its occurrence in several localities in the United States, for Americans to use more tourmaline in their jewels? A Text-Book of Precious Stones for Jewelers and the Gem-Loving Public It is plain that, by means either of the tourmaline or the reflecting glass, we can determine in a moment the direction of vibration in any polarized beam. Six Lectures on Light Delivered In The United States In 1872-1873 Thus, by pure reasoning, we infer that the interposition of a third plate of tourmaline will in part abolish the darkness produced by the perpendicular crossing of the other two plates. Six Lectures on Light Delivered In The United States In 1872-1873 Now suppose, when the two plates are crossed, that we interpose a third plate of tourmaline between them, with its axis oblique to both. Six Lectures on Light Delivered In The United States In 1872-1873 I have not a third plate of tourmaline; but the talc or mica which you employ in your stoves is a more convenient substance, which acts in the same way. Six Lectures on Light Delivered In The United States In 1872-1873 The Ceylon tourmalines are mostly yellow or yellowish green, sometimes fine olive-green. A Text-Book of Precious Stones for Jewelers and the Gem-Loving Public Between the crossed tourmalines, I introduce a film of this crystal with its axis oblique to theirs.
