Page xvi - The objects of the 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.
Page 96 - ... incessantly worked by a steam-engine — air was condensed to an amount sufficient to counteract the external hydrostatic pressure. The ingenious contrivance fully justified the expectations of the engineer ; but the workmen were thus compelled to labor in air condensed under a pressure of about three atmospheres. Among other curious results of this state of things noticed by M. Triger were the remarkable effects of condensed air on combustion. Much annoyance was at first experienced from the...
Page 22 - ... wheeling to the north-east, and following a path nearly parallel to the American coast, to the east of Newfoundland, until they are lost in mid-ocean; the entire path when delineated, resembling a parabolic curve, whose apex is near the latitude of 30°. That their dimensions are sometimes very great, being not less than one thousand miles in diameter, while their path over the ocean can sometimes be traced for three thousand miles. That the barometer, at any given place, falls with increasing...
Page 133 - ... it will be necessary to examine briefly the structure of the League of the Iroquois. At the institution of the league, fifty permanent sachemships or hereditary titles were created, and named. They were then distributed among the nations as follows : nine of them were assigned to the Mohawk, nine to the Oneida, fourteen to the Onondaga, ten to the Cayuga. and eight to the Seneca nation. These titles were made hereditary in certain tribes, some of which received two or more, and others none. These...
Page 70 - We thus, probably, have the fresh-growing calamites entombed along with the debris of the old decaying conifers of some neighbouring shore ; furnishing an illustration of the truth that the most ephemeral and perishable forms may be fossilized and preserved, contemporaneously with the decay of the most durable tissues. The rush of a single summer may be preserved with its minutest striae unharmed, when the giant pine of centuries has crumbled into mould. It is so now, and it was so equally in the...
Page 93 - ... force, defined in the act or law of creation. Turn now to the organic world. The individual is involved in the germ-cell from which it proceeds. That cell possesses certain inherent qualities or powers, bearing a definite relation to external nature, so that, when having its appropriate nidus or surrounding conditions, it will grow, and...
Page 9 - SINCE last we met, the Destroyer has been very busy in our ranks. Besides other beloved and respected associates, our earliest and our latest Presidents have suddenly vanished from our midst; — Redfield, who was the first to suggest the idea of the American Association on its present comprehensive plan, and the first to preside over its deliberations, and Bailey who, we fondly hoped, would occupy the same distinguished position on the present occasion.
Page 101 - The new germ, moreover, takes peculiarities from the parent or from the circumstances to which its ancestry had been exposed during one or more preceding generations. There is then a fixed normal condition or value, and around it librations take place. There is a central or intrinsic law which prevents a species from being drawn off to its destruction by any external agency, while subject to greater or less variations under extrinsic forces. Liability to variation is hence part of the law of a species...
Page 27 - The idea of whirlwinds is indeed much older than Redfield or Reid, being as old as the writings of the psalmist and the prophets ; and we safely admit further, that the doctrine of ocean gales being sometimes of a rotary character, had. been hinted at by several writers, as hints of such a principle as gravitation had long preceded the investigations of Newton ; but the honor of having established, on satisfactory evidence, the rotary and progressive character of ocean storms, and determining their...
Page 29 - Dubuque to the mouth of the Ohio. It forms the upper stratum beneath the soil of all the high lands, both timber and prairie, of all the counties north of the Osage and Missouri, and also St. Louis and the other Mississippi counties on the south.
