Σελίδα 115 - Moving now slowly, but dispensing its genial influences more freely, it finally meets the British Islands. By these it is divided, one part going into the polar basin of Spitzbergen, the other entering the Bay of Biscay, but each with a warmth considerably above the ocean temperature.
Σελίδα xv - Association are, by periodical and migratory meetings, to promote intercourse between those who are cultivating science In different parts of America, to give a stronger and more general impulse and more systematic direction to scientific research, and to procure for the labors of scientific men increased facilities and a wider usefulness.
Σελίδα 115 - With this temperature, it crosses the 40th degree of north latitude, and there, overflowing its liquid banks, it spreads itself out for thousands of square leagues over the cold waters around...
Σελίδα 247 - The predominance of any one of these divisions in a people would stamp them as either eminently intellectual, or eminently cruel, or eminently social. The Mound-builders, assuming these skulls to be typical, were doubtless neither eminent for great virtues nor great vices, but were a mild, inoffensive race, who would fall an easy prey to a crafty and cruel foe. Under the guidance of a superior mind, we can imagine that they would be content to toil, without weighing deliberately the nature or amount...
Σελίδα 254 - From the level of the glabello-occipital line on each side, across the middle of the sagittal suture to the same point on the opposite side. D. The vertical height from the glabello-occipital line. E. The extreme longitudinal measurement. F. The extreme transverse measurement. NOTE. — Professor Jeffreys Wyman, Curator of the Peabody Museum of American Archaeology, in his "Fourth Annual Report...
Σελίδα 14 - had introduced and familiarized the scientific world with those now current ideas respecting the history and vicissitudes of species with which I attempted to deal in a moderate and feeble way. My speculation was based upon the former glaciation of the northern temperate zone, and the inference of a warmer period preceding and perhaps following.
Σελίδα 6 - ... long-lived antediluvians of scripture, to hand down to us, through a few generations, the traditions of centuries, and so tell us somewhat of the history of their race. Fifteen hundred annual layers have been counted, or satisfactorily made out, upon one or two fallen trunks. It is probable that close to the heart of some of the living trees may be found the circle that records the year of our Saviour's nativity. A few generations of such trees might carry the history a long way back.
Σελίδα 61 - Journ. vp 255. passer! over it in 1845, and was so much struck with its defects, although it had been recently erected, that he notified the authorities in regard to them. A few years afterwards it gave way when troops were marching over it.* A few years ago, a terrible disaster befell a battalion of French infantry, while crossing the suspension -bridge at Angiers, in France. Reiterated warnings were given to the troops to break into sections, as is usually done. But the rain was falling heavily,...
Σελίδα 3 - Redwood — including in that name the two species of "big-trees" — belongs to the general Cypress family, but is sui generis. Thus isolated sytematically, and extremely isolated geographically, and so wonderful in size and port, they more than other trees suggest questions. Were they created thus local and lonely, denizens of California only; one in limited numbers in a few choice spots on the Sierra Nevada, the other along the coast range from the Bay of Monterey to the frontiers of Oregon? Are...
Σελίδα 131 - How far it may extend, whether it exists simply as a feature of the immediate region, or as part of a great unexplored area communicating with the Polar Basin, may be questions for men skilled in scientific deductions.
