Page 169 - For this they willingly are ignorant of, that by the word of God the heavens were of old, and the earth standing out of the water and in the water, whereby the world that then was, being overflowed with water, perished; but the heavens and the earth, which are now, by the same word are kept in store, reserved unto fire against the day of judgment and perdition of ungodly men.
Page 181 - ... water, the water enters into combination with it, and becomes solid, and on its passing from the liquid to the solid state, a large amount of heat is evolved. The lime falls to pieces, having become hydrated, or, in common language, slacked. It is slightly soluble in water, as every one knows, producing the well-known, liquid called lime-water. When combined with water— for it must be hydrated — it unites readily with carbonic acid, forming carbonate of lime. Carbonate of lime is a mineral...
Page 108 - He then examined the grounds upon which this hypothesis is based. Numerous observations of the augmentation of temperature, at increasing depths from the surface of the earth, no longer leave room for doubt that the vast mass of materials constituting the interior of our globe U at the present moment at a temperature far higher than that of the surface.
Page 113 - Moon must, in accordance with all analogy, have been attended with contraction, which can scarcely be conceived as occurring without the development of a cavernous structure in the interior. Much of this cavernous structure would doubtless communicate, by means of fissures, with the surface ; and thus there would be provided an internal receptacle for the ocean, from the depths of which even the burning Sun of the long lunar day would be totally unable to dislodge more than traces of its vapour.
Page 112 - ... and whose external curvature is towards the north. Beyond the second ridge a talus slopes gradually down northwards to the general level of the lunar surface, the whole presenting an appearance reminding the observer of the concentric moraines of the Rhone glacier. These ridges are visible for the whole period during which that portion of the Moon's surface is illuminated ; but it is only about the third day after the first quarter, and at the corresponding phase of the waning Moon, when the...
Page 140 - ... which they were obtained. The relation of the high-level gravels (in which the implements were found) to the lower-level gravels of the valley of the Avon was next discussed, and the geological features of the former deposits particularly described, lists of the fossils (including the Mammalia and the Land and Freshwater Shells) being also given. Mr. Evans came to the conclusion that the fossils bore evidence of the climate, at the time when they were deposited, having been more rigorous, at...
Page 70 - The solution is, as I said, durable in proportion to its purity. It is not easily preserved beyond a few days unless considerably diluted. It becomes opalescent after a short time, and then the jelly separates ; and once separated, it cannot be redissolved in water. When the jelly is formed suddenly it is always more or less opalescent. Here is sime which has been formed slowly by Professor Graham.
Page 119 - ... by further geological movements becomes again exposed to the action of its natural solvents, water and carbonic acid, and is thus restored to active service in the organisms of plants and lower animals, through which it passes, to complete the mighty cycle of its movements into the blood and tissues of the human frame. While circulating thus, age after age, through the three kingdoms of nature, phosphorus is never for a moment free. It is throughout retained in combination with oxygen, and with...
Page 106 - Hounding the promontory of the Naze and proceeding northward, the coast presents, with slight exceptions, the same general features until the Arctic circle is approached, when the character of the scenery rather suddenly changes. The rocky hills acquire the dignity of mountains, and tower up in rugged, sharp, and fantastic peaks, contrasting strongly with the rounded summits of the lower latitudes. But these arctic peaks owe their immunity .from the abrading action of ice solely to their height;...
Page 112 - Frankland has perhaps provided us with some data towards answering the second question. A study of the glacial epoch on our own globe, he asserts, renders it probable that the other bodies belonging to our solar system have either already passed through a similar epoch, or are destined still to encounter it. With the exception of the polar ice of Mars we have hitherto obtained no certain glimpse into the thermal and meteorological condition of the planets ; and, indeed, the Moon is the only body...
