Seite 78 - It is the purpose of the present paper to show that the above requirements are practically fulfilled by lead and by helium also, in so far as the gaseous nature of the latter element will permit of its retention in the minerals. The suggestion that lead was one of the final (inactive) disintegration products of uranium was first made by the writer in a paper presented before the New York Section of the American Chemical Society on February 10, 1905.
Seite 73 - In the multicellular animal, especially for those higher reactions which constitute its behaviour as a social unit in the natural economy, it is nervous reaction which par excellence integrates it, welds it together from its components, and constitutes it from a mere collection of organs an animal individual.
Seite 413 - ... that the ratio of the sines of the angles of incidence and refraction is constant for refraction in the same medium, was effected by Snell and Descartes.
Seite 71 - The Fossils of the Silurian (Upper Silurian) rocks of Keewatin, Manitoba, the North Eastern shore of lake Winnipegosis and the lower Saskatchewan River. 6. The Canadian species of Plectoceras and Barrandeoceras. 7. Illustrations of seven species of fossils from the Cambrian, Cambro-Silurian and Devonian rocks of Canada.
Seite 113 - Eozoic seon of dominantly soft-bodied animals and the post-Cambrian son of dominantly lime-secreting animals. The notable fossilization of brachiopods, trilobites, molluscs, etc., was impossible until near the beginning of Cambrian time. Indeed, the conditions for truly abundant fossilization of calcareous forms were not established until after the Cambrian period. The striking...
Seite 83 - Preliminary account of Goldfield, Bullfrog, and other mining districts in southern Nevada, by FL Ransome, with notes on the Manhattan district, by GH Garrey and WH Emmons.
Seite 66 - Martin. 1906. 36 pp., 5 pis. WS 164. Underground waters of Tennessee and Kentucky west of Tennessee River and of an adjacent area in Illinois, by LC Glenn.
Seite 229 - Alternating wet and dry seasons. "2. Their restriction in altitude is only apparent. Their present lines of altitude merely mark ancient or existing basin floors or plains. "3. They are derived from mineralized solutions brought to the surface by capillarity, and are essentially replacements (either mechanical or metasomatic) of soil or of rock decomposed in situ, or of both.
Seite 151 - If the vanadium is disregarded, the ironnickel sulphide has the formula (FeNi)S2, with iron to nickel as 1.70 to 1, or nearly 5 to 3. A pyrite with such a high proportion of nickel is unknown. But a single one of the analyses quoted in Hintze's Handbook of Mineralogy shows anywhere near 6 per cent, nickel; this one, however, showing also about 3 per cent, of cobalt. The nearest approach to the present case is seen in the mineral gunnarite, 3FeS2, 2NiS, incompletely described by Lanstrom with density...
Seite 185 - ... consolidated sands, clays, marls, etc., in part of colors unknown to the drift, and probably representing Tertiary strata underlying the drift and filling deep depressions or valleys in the harder formations or true bed rocks of the region. The artesian well of N. Ward & Co., on Spectacle Island, 560 feet deep, passed through at least 360 feet of unconsolidated material, only part of which could be regarded as glacial drift ; and the deep well at the corner of High and Purchase streets in Boston,...
