Page xxxii - 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 110 - THE greatest improvement in the productive powers of labour, and the greater part of the skill, dexterity, and judgment with which it is anywhere directed, or applied, seem to have been the effects of the division of labour.
Page 109 - Engineer, being the art of directing the great sources of power in Nature for the use and convenience of man...
Page 241 - Iroquois may aid in understanding the analyses of the names of the cosmogonic gods of this cult. The Iroquoian account, as told by the Onondaga shamans, relates that before the formation of this earth there existed in the sky a world similar in every respect to this and inhabited by people endowed with faculties similar to their own. That sky-world had no need of the light of the sun or of the moon.
Page 114 - The Bessemer invention takes its rank with the great events which have changed the face of society since the Middle Ages. The invention of printing, the construction of the magnetic compass, the discovery of America and the introduction of the steam engine are the only capital events in modern history which belong to the same category as the Bessemer process.
Page 50 - Marston,f who, besides confirming Wertheim's conclusion, shows that, " for small strains at least, the colors seen in a strained glass body, when polarized light is passed through it in a direction parallel to one of the axes of strain, are measured by the algebraic difference of the intensities of those two principal strains whose directions are perpendicular to the direction of the polarized light.
Page 49 - Runge5 have discovered interesting relations among the spectral lines of a large number of terrestrial elements, arranging them into series whose distribution manifests chemical relationship quite analogous to that indicated in Mendelejeff's periodic law.
Page 144 - ... beginnings, divided into three parts, one upon Labrador, another northwest of Hudson bay, as shown by Tyrrell's observations, and a third upon the northern part of British Columbia. From my studies of the glacial lake Agassiz, whose duration was probably only about 1,000 years, the whole Champlain epoch of land depression, the departure of the ice-sheet because of the warm climate so restored, and most of the re-elevation of the unburdened lands, appear to have required only a few (perhaps four...
Page 39 - Thus the neutral chlorides of sodium and potassium, after being rendered luminous by action of kathode rays, are thereby reduced to the condition of subchloride so as to give a distinctly alkaline reaction. Many substances moreover which manifest no luminescence at ordinary temperatures after exposure, or which do so for only a short time, become distinctly luminescent when warmed. This striking phenomenon is sufficient to warrant the use of a special name, thermo-luminescence. Among such substances...
Page 143 - STAGE. Depression of the ice-burdened areas mostly somewhat below their present heights, as shown by fossiliferous marine beds overlying the glacial drift up to 300 feet above the sea in Maine, 560 feet at Montreal, 300 to 400 feet from south to north in the basin of Lake Champlain, 300 to 500 feet southwest of Hudson and James bays, and similar or less altitudes on the coasts of British Columbia, the British Isles, Germany, Scandinavia and Spitzbergen.
