Page xiv - 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 100 - ... 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 - Islands, pursuing, at first, a course toward the northwest, as far as the latitude of 30° and then gradually wheeling to the northeast, and following a path nearly parallel to the American coast, to the east of Newfoundland, until they are lost in midocean ; 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...
Page 137 - Nine of them were assigned to the Mohawk nation; nine to the Oneida; fourteen to the Onondaga; ten to the Cayuga ; and eight to the Seneca. The sachems, united, ibrmed the Council of the League; the ruling body in which resided the executive, legislative, and judicial authority.
Page 74 - 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 123 - But — in addition to the fact that the measurements now supplied are only the more carefully noted data which have tended to confirm conclusions suggested, by previous examinations, in a less detailed manner, of a larger number of examples — an investigation of the materials which supplied the elements of earlier inductions will show that only in the case of the ancient " Toltecan" tribes did Dr Morton examine nearly so many examples ; while, in relation to what he designated the
Page 203 - Our snow storms of winter are from the NE by E. ; and for some hours before they form, the eastern horizon becomes gradually covered with heavy strata clouds of a deep leaden hue. The upper strata of clouds are generally a mixture of cirri cumulus and stratus, moving from the south ; but the surface wind is from the point I have stated, NE by E. The wind during these storms often...
Page 14 - Mr. Redfield met with obstacles which in ordinary minds would have quenched the desire of intellectual progress. Yet every year added largely to his scientific acquisitions, and developed more fully his intellectual and moral energies. Meanwhile his active mind left its impress on the quiet community where he lived, in devising and carrying out various plans for advancing their social comfort and respectability, in the improvement and...
Page 21 - I chanced at that period to meet him for the first time on board a steamboat on the way from New York to New Haven. A stranger accosted me, and modestly asked leave to make a few inquiries respecting some observations I had recently published in the American Journal of Science on the subject of Hailstorms. I was soon made sensible that the humble inquirer was himself a proficient in meteorology.
Page 21 - ... for modifying ; but the great features of that theory appear there in bold relief. Three years afterwards he published, in the 25th volume of the same journal, an elaborate article on the hurricanes of the "West Indies, in the course of which he gives a full synopsis of the leading points of his doctrine as matured by a more extended analysis of the phenomena of storms than he had made when he published his first essay.
