Page 183 - 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 102 - ... 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 78 - Hence, when individuals multiply from generation to generation, it is but a repetition of the primordial type-idea ; and the true notion of the species is not in the resulting group but in the idea or potential element which is at the basis of every individual of the group...
Page 117 - 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 106 - Northern continent, the conclusions still go far beyond anything established by absolute proof ; and the subsequent labors of Morton himself, and still more, of some of his successors, seem to have been conducted on the principle of applying practically, and in all possible bearings, an established and indisputable scientific truth, instead of testing by further evidence a novel and ingenious hypothesis.
Page 23 - I was soon sensible that the humble inquirer was himself a proficient in meteorology. In the course of the conversation, he incidentally brought out his theory of the laws of our Atlantic gales, at the same time stating the leading facts on which his conclusions were founded. This doctrine was quite new...
Page 104 - ... absolute increase in the rapidity of burning. In the absence of direct experimental evidence, it may be admissible to apply general reasoning based upon well-known physical principles. So far as an increase of temperature influences the density of the air, it is sufficiently evident, that its effects must be equivalent to a diminution of barometric pressure ; and, consequently, must tend to retard the process of combustion. Assuming the temperature of the flame to be constant, it is likewise...
Page 101 - Davy's experiments show that the rate of combustion was retarded by the rarefaction, and accelerated by the condensation of the air. The most satisfactory results in relation to the influence of condensed air on the process of combustion are those incidentally furnished about sixteen years ago, by M. Triger, a French civil engineer, during the operations necessary for working a bed of coal lying under the alluvium bordering the river Loire, near Languin, in the department of Maine-et-Loire.
Page 27 - Redfield and Dove", although the conclusion was arrived at by totally different methods of investigation. Mr. Redfield says, in a note to his paper on the Cuba hurricane, published in 1846, that it was not until seven years after the publication of his theory of the rotary and progressive character of storms, that he became acquainted with the suggestions and opinions of Col. Capper, and with the particular views and elucidations published by Professor T)o\'6 in his paper on Barometric Minima, found...
Page 235 - Soil. — Nearly all the soils of Missouri possess all the ingredients necessary to the complete development of the vine ; but some of them are too heavy, wet, and cold, unless improved by artificial means. This is true to some extent of those on the bluffs of the Mississippi and Missouri, where nearly all the vineyards of our State are located. These soils are based upon the Bluff- formation, where it contains more clay and less lime than in the western counties, which possess our best soils.
