Стр. 867 - THE ELEMENTS OF FORESTRY. Designed to afford Information concerning the Planting and Care of Forest Trees for Ornament or Profit, with Suggestions upon the Creation and Care of Woodlands. By FB HOUGH. Large crown 8vo, IDS.
Стр. 776 - When we see an ant-hill, tenanted by thousands of industrious inhabitants, excavating chambers, forming tunnels, making roads, guarding their home, gathering food, feeding the young, tending their domestic animals, — each one fulfilling its duties industriously, and without confusion, — it is difficult altogether to deny to them the gift of reason ; and the preceding observations tend to confirm the opinion that their mental powers differ from those of men, not so much in kind as in degree.
Стр. 490 - Beagle,' as naturalist, I was much struck with certain facts in the distribution of the organic beings inhabiting South America, and in the geological relations of the present to the past inhabitants of that continent.
Стр. 131 - Annual Report of the Curator of the Museum of Comparative Zoology at Harvard College to the President and Fellows of Harvard College for 1879—1880.
Стр. 266 - Intermixed with much ashes, were found not far from two hundred pipes, carved in stone, many pearl and shell beads, numerous discs, tubes, etc. of copper, and a number of other ornaments of copper, covered with silver, etc., etc. The pipes were much broken up, — some of them calcined by the heat, which had been sufficiently strong to melt copper, masses of which were found fused together in the centre of the basin.

Стр. 700 - Plato is not, as has been long supposed, fable, but veritable history. 3. That Atlantis was the region where man first rose from a state of barbarism to civilization. 4. That it became, in the course of ages, a populous and mighty nation, from whose overflowings the shores of the Gulf of Mexico, the Mississippi River, the Amazon, the Pacific coast of South America, the Mediterranean, the west coast of Europe and Africa, the Baltic, the Black Sea, and the Caspian were populated by civilized nations.
Стр. 869 - Hovey (Horace C.) Celebrated American Caverns, especially Mammoth, Wyandot, and Luray; together with Historical, Scientific, and Descriptive Notices of Caves and Grottoes in other Lands. Maps and illustrations.
Стр. 500 - In many parts of England a weight of more than ten tons of dry earth annually passes through their bodies and is brought to the surface on each acre of land...
Стр. 512 - ... remarkable of all the indices that point out man's inferiority. In the mammalian embryo the face is formed under the fore brain or cerebral hemispheres. In our faces the foetal disposition is permanently retained, with changes, which when greatest are still inconsiderable. In quadrupeds the facial region acquires a prominent development leading to the specialization of the jaws and surrounding parts, which brings the face to a condition much higher than that of the foetus. Hence the projecting...
Стр. 406 - ... with two masticating plates, one in the gum the other in the under jaw. The udders of the female, which abounded in milk, were placed between the fore-limbs. The flesh and milk resembled those of horned cattle, indeed in Steller's opinion surpassed them. The sea-cows were almost constantly employed in pasturing on the sea-weed which grew luxuriantly on the coast, moving the head and neck while so doing much in the same way as an ox. While they pastured they showed great voracity, and did not...
