Page 108 - City had given to the Metropolitan Museum of Art and the American Museum of Natural History.
Page 107 - The inner parts of the country were not less savage and horrible. The wild rocks raised their lofty summits till they were lost in the clouds, and the valleys lay covered with everlasting snow. Not a tree was to be seen, nor a shrub even big enough to make a toothpick. The only vegetation we met with was a coarse strong-bladed grass growing in tufts, wild burnet, and a plant like moss, which sprung from the rocks.
Page 167 - AM the Flying Dutchman crossed our bows. A strange red light as of a phantom ship all aglow, in the midst of which light the masts, spars, and sails of a brig 200 yards distant stood out in strong relief as she came up on the port bow.

Page 196 - The art of preserving health; that is, of obtaining the most perfect action of body and mind during as long a period as is consistent with the laws of life. In other words, it aims at rendering growth more perfect, decay less rapid, life more vigorous, death more remote.
Page 291 - The dynamics of the subject, so far as a single liquid is concerned, is absolutely comprised in the mathematics without symbols which I have put before you. Twenty pages covered with sextuple integrals could tell us no more. Hitherto we have only considered mutual attraction between the parts of two portions of one and the same liquid — water for instance. Consider, now, two different kinds of liquid : for instance, water and carbon disulphide (which, for brevity, I shall call sulphide). Deal with...

Page 45 - C — known as the absorption, was introduced about 1850. The principle employed is chemical or physical rather than mechanical, and depends on the fact that many vapours of low boiling point are readily absorbed by water, but can be separated again by the application of heat to the mixed liquid. A considerable number of machines in which ammonia was used in combination with water as an absorbent were made by Carre...
Page 139 - Fizeau in 1851 is essentially correct, and that the luminiferous ether is entirely unaffected by the motion of the matter which it permeates.
