Seite 626 - SOUND : a Course of Eight Lectures delivered at the Royal Institution of Great Britain. By JOHN TYNDALL, LL.DFRS New Edition, crown 8vo.
Seite 328 - The POLAR WORLD; a Popular Description of Man and Nature in the Arctic and Antarctic Regions of the Globe. By Dr.
Seite 587 - ... highly probable, though not completely demonstrated, the applicability to living beings of the laws which have been ascertained with reference to dead matter, I feel constrained at the same time to admit the existence of a mysterious something lying beyond, a something sui generis, which I regard, not as balancing and suspending the ordinary physical laws, but as working with them and through them to the attainment of a designed end. What this something which we call life may be is a profound...
Seite 173 - When the durion strikes a man in its fall, it produces a dreadful wound, the strong spines tearing open the flesh, while the blow itself is very heavy ; but from this very circumstance death rarely ensues, the copious effusion of blood preventing the inflammation which might otherwise take place. A Dyak chief informed me that he had been struck down by a durion falling on his head, which he thought would certainly have caused his death, yet he recovered in a very short time.

Seite 444 - ... embraces, in one stupendous analogy, the growth of a solar system from molecular chaos, the shaping of the earth from the nebulous cubhood of its youth, through innumerable changes and immeasurable ages, to its present form ; and the development of a living being from the shapeless mass of protoplasm we term a germ.
Seite 271 - IT has often been maintained on chemical grounds that hydrogen gas is the vapour of a highly volatile metal. The idea forces itself upon the mind that palladium with its occluded hydrogen is simply an alloy of this volatile metal, in which the volatility of the one element is restrained by its union with the other, and which owes its metallic aspect equally to both constituents.
Seite 144 - In about two minutes,' writes the Professor in his preliminary report, dated the I4th of October, 'a reaction commenced. At first a moderate quantity of brown nitrous fumes escaped; these were followed by copious blackish, then grey, then whitish fumes, produced by the escape of steam, carrying with it in suspension a portion of the flux. After the lapse of five or six minutes...
