Three Expeditions into the Interior of Eastern Australia, Volume 1 Those who have not the scientific spirit can scarcely understand that one's opinions are formed outside of one by a sort of impersonal concretion of which one is, so to speak, the spectator. Recollections of My Youth These concretions are well known to naturalists, and form part of the beautiful specimens which are preserved in the cabinets of collectors, and which the German mineralists have termed Drusen. Theory of the Earth, Volume 1 (of 4) It does not seem, however, altogether impossible that some of the singular "concretions" of this formation may ultimately prove to have an organic structure, though others would appear to be clearly of purely inorganic origin. The Ancient Life History of the Earth A Comprehensive Outline of the Principles and Leading Facts of Palæontological Science We found on other parts of this open ground large blocks composed of irregular concretions of ironstone, covered with a thin coating of compact brown haematite.

The Gutenberg Webster's Unabridged Dictionary Section T, U, V, and W Below this stratum was clay mixed with calcareous concretions. Three Expeditions into the Interior of Eastern Australia, Volume 1 But the true theory of these concretions, under any modification of temperature, is attended with considerable difficulty: and it is certain that the process is far from being confined to the warmer latitudes. Narrative of a Survey of the Intertropical and Western Coasts of Australia Performed between the years 1818 and 1822 — Volume 2 From these facts, I may now be allowed to draw the following conclusions: 1st, That concretion had proceeded from the surface of the agate body inwards.

Tess of the d'Urbervilles The four moments imply one another regressively by their concretion. Aesthetic as Science of Expression and General Linguistic On the southern side of the triangular plain is a sandy beach, where the sand in some places has formed itself by concretion into rocks, in several of which are large cisterns. Travels in Syria and the Holy Land I shall now give an example of this fallaceous manner of reasoning; it is in the case of certain mineral appearances which are erroneously considered as stalactical concretions.

Scientific American Supplement, No. 358, November 11, 1882 History means concretion and individuality, law and concept mean abstraction and universality. Aesthetic as Science of Expression and General Linguistic This clouds in cooling, and after a certain time it separates in small crystals of indeterminate form which unite in warty concretions. Scientific American Supplement, No. 324, March 18, 1882 These are certain concretions of calcedony, and also of iron-ore, which are thought to have such resemblance to stalactical concretions as, by some superficial observers, to be reckoned of the same kind.

Scientific American Supplement, No. 358, November 11, 1882 Poetry is the language of sentiment; prose of the intellect; but since the intellect is also sentiment, in its concretion and reality, so all prose has a poetical side. Aesthetic as Science of Expression and General Linguistic It gives rise to the formation of concretions, and that not only in the mouth, but also, as I have shown, in the salivary ducts and urinary bladder. Scientific American Supplement, No. 303, October 22, 1881 If this be admitted, it will follow that we have no proof of any proper mineral concretion except that which had proceeded by congelation from the fluid state of fusion. Theory of the Earth, Volume 1 (of 4) At one side of the concretion a piece had been broken off exposing an incisor tooth which represented the nucleus of the formation. Anomalies and Curiosities of Medicine The marble crags are overspread with a concretion, which makes them look as gray as granite, except where the continual flow of water keeps them of a snowy whiteness. Passages from the American Notebooks, Volume 1 Or, better, when this is conceived as itself a category or function, which gives knowledge of things in their concretion and individuality? Aesthetic as Science of Expression and General Linguistic The clay which separates these amygdaloid concretions arises from the decomposition of their crust. Personal Narrative of Travels to the Equinoctial Regions of America, During the Year 1799-1804 — Volume 2 Now, these principles are always to be perceived, more or less, in all the bizarre or fantastical, as well as regular shapes which are produced by stalactical concretions.

Personal Narrative of Travels to the Equinoctial Regions of America, During the Year 1799-1804 — Volume 2 Such various inconsistent opinions, respecting petrifaction or mineral concretion, as I have now exposed, opinions that are not founded on any sound physical principle, authorise me to conclude that they are all erroneous. Theory of the Earth, Volume 1 (of 4) The prevailing rock granite, traversed by numerous veins of dark trap, and in the latter part of the day porphyry and schist appeared; concretions of limestone were frequent near the trap veins. Journals of Australian Explorations The rock is not one mass of stone, but a concretion of pebbles and earth, so firm that it does not appear to have mouldered. Life of Johnson, Volume 5 Tour to the Hebrides (1773) and Journey into North Wales (1774) I think your common sense will tell you that these pebbles are not mere concretions; that is, formed out of the substance of the clay after it was deposited. Town Geology As it has come down to us, however, it is not a pamphlet merely, but a concretion of pamphlets. The Life of John Milton Volume 3 1643-1649 The induration of mortar arises from the solution of a stony substance, and the subsequent concretion of that dissolved matter, operations purely chemical.

Journal of an Overland Expedition in Australia : from Moreton Bay to Port Essington, a distance of upwards of 3000 miles, during the years 1844-1845 Ground water seeping through the pores of rocks may gather minerals disseminated throughout them into nodular masses called concretions. The Elements of Geology The chief mass of this formation consists of a dark grey argillaceous shale with calcareous concretions, having a maximum thickness of 1000 feet. The Student's Elements of Geology Some of these spherical balls were encircled in the line of their equators, by a necklace-like row of smaller concretions. Geological Observations on South America Why does he not rather explain, upon this principle, the known concretion of some body, from a fluid state, or, conversely, the known solution of some concreted body? Theory of the Earth, Volume 1 (of 4) I presume that these concentric layers were formed by the shrinking of the concretion, as it became compact. Volcanic Islands Clays and shales often contain concretions of lime carbonate, of iron carbonate, or of iron sulphide. The Elements of Geology The shale, like the Lower Ludlow, often contains elliptical concretions of impure earthy limestone. The Student's Elements of Geology The cliffs here are about eight hundred feet in height: they consist, wherever I could examine them, of fine-grained, yellowish, earthy sandstones, with ferruginous veins, and with concretions of hard calcareous sandstone. Geological Observations on South America We know the chemical process by which one or two stony concretions may be formed among bodies passing from one state to another. Theory of the Earth, Volume 1 (of 4) Some of the larger concretions consist of a mere spherical shell, filled with slightly consolidated ashes. Volcanic Islands Some fossil, such as a leaf or shell, frequently forms the nucleus around which the concretion grows. The Elements of Geology They are not unfrequently covered with barnacles, showing that they were not formed as concretions in the stratum where they now lie buried, but had been previously consolidated. The Student's Elements of Geology The third bed is pale-coloured Pampean mud; and the fourth is of the same nature, but darker coloured, including in its lower part horizontal layers and lines of concretions of not very compact pinkish tosca-rock. Geological Observations on South America Now, this last case is that of almost all mineral concretions. Theory of the Earth, Volume 1 (of 4) The concretions contain a small proportion of carbonate of lime: a fragment placed under the blowpipe decrepitates, then whitens and fuses into a blebby enamel, but does not become caustic. Volcanic Islands In many other rocks concretions are made by the process of REPLACEMENT. The Elements of Geology The skulls, teeth, and the greater portions of the skeleton, nay, even a large part of the skin, of two of these reptiles have been faithfully preserved in the centre of spheroidal concretions of clay-ironstone. The Student's Elements of Geology These concretions often unite into irregular strata; and over very large tracts of country, the entire mass consists of a hard, but generally cavernous marly rock: some of the varieties might be called calcareous tuffs. Geological Observations on South America These are the shape and motions of the fluid which gives the calcareous concretion. Theory of the Earth, Volume 1 (of 4) The surrounding ashes do not contain any carbonate of lime; hence the concretions have probably been formed, as is so often the case, by the aggregation of this substance. Volcanic Islands Molecule by molecule the rock is removed and the mineral of the concretion substituted in its place. The Elements of Geology After deposition similar particles seem often to exert a mutual attraction on each other, and congregate together in particular spots, forming lumps, nodules, and concretions. The Student's Elements of Geology Dr. Carpenter has kindly examined under the microscope, sliced and polished specimens of these concretions, and of the solid marl-rock, collected in various places between the Colorado and Santa Fe Bajada. Geological Observations on South America These appearances are thought to be observed in the calcedony and ferruginous concretions, which has led some mineralists to conclude, that those concretions had been formed in the same manner, by means of water. Theory of the Earth, Volume 1 (of 4) I have not met with any account of similar concretions; and considering their great toughness and compactness, their occurrence in a bed, which probably has been subjected only to atmospheric moisture, is remarkable. Volcanic Islands The concretion may in this way preserve intact the lamination lines or other structures of the rock. The Elements of Geology Everybody sees that eggs have the nature of a concretion or consistence in some animal or other, but want those organs, veins, and muscles which animals enjoy. Complete Works of Plutarch — Volume 3: Essays and Miscellanies The mud, wherever I examined it, even close to the concretions, did not contain any carbonate of lime. Geological Observations on South America But those mineral concretions, which are supposed to be stalactical, are contained in half that space, or are nearer to each other than the tenth or twentieth of an inch. Theory of the Earth, Volume 1 (of 4) One of the layers of a pinkish colour, and chiefly derived from small, decomposed fragments of pumice, is remarkable, from containing numerous concretions. Volcanic Islands In soft clays concretions may, as they grow, press the clay aside. The Elements of Geology The spirit hovering above the spires was as different from its concretions in their caps and gowns as ever the spirit of Christ was from church dogmas. The Island Pharisees These concretions are remarkable from the great number of large silicified bones, apparently of cetaceous animals, which they contain; and likewise of a shark's teeth, closely resembling those of the Carcharias megalodon. Geological Observations on South America In the case of stony substances, I have shown how unfounded all their theories are for the production of those concretions, crystallizations, and consolidated bodies. Theory of the Earth, Volume 1 (of 4) Numerous white balls appearing like pisolitic concretions, from the size of a walnut to that of an apple, are embedded in this deposit; they usually have a small pebble in their centres. Volcanic Islands While geodes grow from the outside inwards, concretions grow outwards from the center. The Elements of Geology The quartz of the strata might here move into the position of the folia without much more movement of molecules than in the formation of concretions. More Letters of Charles Darwin — Volume 2 Shells of the following species, of which the gigantic Oyster and Perna are the most conspicuous, are numerously embedded in the concretions:— 1. Geological Observations on South America The only true stalactical bodies are of a calcareous substance; they are formed by water containing this substance in a dissolved state; and the principles upon which this particular concretion is formed are well known. Theory of the Earth, Volume 1 (of 4) At this location, in three or four fathoms of water between the Paeu and Vana reefs, there lay some anchors, cannons, and ingots of iron and lead, all caked with limestone concretions. Twenty Thousand Leagues Under the Sea The visitor should not fail to cross the Creek either above or below the Bridal Veil Falls, for on the further side are a number of water concretions well worth seeing. The Grand Canyon of Arizona; how to see it When a gland includes only a few very small concretions, or, as sometimes happens, none at all, it is easily overlooked. The formation of vegetable mould through the action of worms, with observations on their habits Foliation and cleavage resemble each other in the planes winding round concretions, and in becoming tortuous where veins of quartz abound. Geological Observations on South America Let us now consider what it is that we have to explain, upon the supposition of those concretions being formed from a solution. Theory of the Earth, Volume 1 (of 4) Another weed, known by the name velp and boasting four–foot leaves, was crammed into the coral concretions and carpeted the ocean floor. Twenty Thousand Leagues Under the Sea The ground was encrusted with sulphur and crystalline concretions.

The formation of vegetable mould through the action of worms, with observations on their habits The strata which I examined consisted of fine-grained muddy sandstones, with fragments of lignite and concretions of calcareous sandstone. Geological Observations on South America This is a question that does not seem to have entered into the heads of our naturalists who attempt to explain petrifaction or mineral concretion from aqueous solutions. Theory of the Earth, Volume 1 (of 4) They come nearer in character to the Yellowstone geysers, their waters depositing true geyserite, or silicious concretions. The San Francisco calamity by earthquake and fire But he had had an eczema on the back of his neck, and now concretions were forming in his ears, which pointed, it was feared, to decay of the bones of the skull. Four Short Stories By Emile Zola Claparede says very little about the structure of the two anterior glands, and he supposes that the calcareous matter of which the concretions are formed is derived from the four posterior glands. The formation of vegetable mould through the action of worms, with observations on their habits During a second visit of the "Beagle" to Concepcion, Mr. Kent collected for me some silicified wood and shells out of the concretions in the sandstone from Tome, situated a short distance north of Lirguen. Geological Observations on South America Now I here maintain, that philosophers have judged in no other manner than by this false analogy, when they conclude that water is the agent by which mineral concretions have been formed. Theory of the Earth, Volume 1 (of 4) Humboldt, on saline incrustations. —on foliations of gneiss. —on concretions in gneiss. Geological Observations on South America Iron, oxide of, in lavas. —in sedimentary beds. —tendency in, to produce hollow concretions. —sulphate of. Geological Observations on South America When a gland is completely filled with a single large concretion, there are no free cells, as these have been all consumed in forming the concretion. The formation of vegetable mould through the action of worms, with observations on their habits From Level of Sea to Surface of plain, 252 feet above sea, through levels F, E, D and C: F.—Lower sandstone, with concretions and silicified bones, with fossil shells, all, or nearly all, extinct. Geological Observations on South America The cliffs in Sebastian Bay are 200 feet in height, and are composed of fine sandstones, often in curvilinear layers, including hard concretions of calcareous sandstone, and layers of gravel. Geological Observations on South America Again there were other concretions, irregularly formed, and composed of a hard, compact, ash- coloured stone, with an almost porcelainous fracture, adhesive to the tongue, and without any calcareous matter. Geological Observations on South America It was thus evident that the concretions are formed from the lime contained within the free calciferous cells. The formation of vegetable mould through the action of worms, with observations on their habits But if such a concretion, or one of only moderately large size, is dissolved in acid, much membranous matter is left, which appears to consist of the remains of the formerly active lamellae. The formation of vegetable mould through the action of worms, with observations on their habits At eighty miles from the coast, in a cliff thus composed, there were a few layers of ferruginous sandstone, and of an argillaceous sandstone with concretions of marl like those in the Pampas. Geological Observations on South America They differ also conspicuously in generally containing several small, or two or three larger, or a single very large concretion of carbonate of lime, as much as 1.5 mm. in diameter. The formation of vegetable mould through the action of worms, with observations on their habits The large concretions are round or oval, and exteriorly almost smooth. The formation of vegetable mould through the action of worms, with observations on their habits After the formation and expulsion of a large concretion, new lamellae must be developed in some manner. The formation of vegetable mould through the action of worms, with observations on their habits When an anterior gland contains several minute concretions, some of these are generally angular or crystalline in outline, while the greater number are rounded with an irregular mulberry-like surface. The formation of vegetable mould through the action of worms, with observations on their habits In the gneiss, concretions of granular feldspar and others of garnets with mica occur. Geological Observations on South America A very small concretion was removed from between two of the lamellae within an anterior gland. The formation of vegetable mould through the action of worms, with observations on their habits As the smaller concretions increase in size, they come into contact and unite, thus enclosing the now functionless lamellae; and by such steps the formation of the largest concretions could be followed. The formation of vegetable mould through the action of worms, with observations on their habits The concretions found in the intestines and in the castings often have a worn appearance, but whether this is due to some amount of attrition or of chemical corrosion could not be told.
