עמוד 508 - Chairman), in co-operation with the American Chemical Society. Special attention was also given to arrangements for co-operation with the scientific Bureaus of the Government, the Committee of Physicians and Surgeons, the Naval Consulting Board, the national societies devoted to branches of science in which committees were immediately needed, the national engineering societies, the larger research foundations, certain universities and schools of technology, and the leading investigators in many fields...
עמוד 305 - Maine. PHOEBUS AARON THEODORE LEVENE, physiological chemist, Rockefeller Institute for Medical Research, New York City. OTTO FOLIN, physiological chemist, Harvard Medical School, Boston, Mass. SCIENTIFIC SESSIONS Two public lectures on the WILLIAM ELLERY HALE FOUNDATION were given on April 17 and 19 by HENRY FAIRFIELD OSBORN, President of the American Museum of Natural History, on The Origin and Evolution of Life on the Earth. Four public scientific sessions were held on April 17 and 18 at which...
עמוד 509 - MY DEAR DR. WELCH: I want to tell you with what gratification I have received the preliminary report of the National Research Council, which was formed at my request under the National Academy of Sciences. The outline of work there set forth and the evidences of remarkable progress towards the accomplishment of the object of the Council are indeed gratifying.
עמוד 100 - The observations in the Bahamas were made on artificially planted and naturally attached colonies at the east end of South Bight, Andros Island. The Florida corals were measured annually; those in the Bahamas were measured in 1912 and again in 1914. The average growth rate for each species at each station has been computed. The size of the colonies of all species of corals seems limited, but some attain large dimensions, 2 to 3 meters or even more in diameter, and nearly as much in height, while...
עמוד 320 - This effect persists after the superior and the recurrent laryngeal nerves are severed. Experiments have shown that the nerve impulses pass out through both the superior and inferior cervical ganglia. Simulation of the main trunk of the vagus nerve in a curarized animal, or injection of pilocarpine (which excites vagus endings) has no effect in producing an action current in the thyroid gland. The influence of sympathetic impulses is not indirect through local anemia of the gland, for when the blood...
עמוד 384 - We may evaluate our results in general terms as follows: 1. There is no evidence that specific germinal changes have been induced by the alcoholic treatment, at least in those germ cells which produced zygotes.
עמוד 662 - Briefly stated, this theory is that all cross-fiber veins are formed through a process of lateral secretion, the growing veins making room for themselves by pushing apart the inclosing walls...
עמוד 509 - The outline of work there set forth and the evidences of remarkable progress toward the accomplishment of the object of the council are indeed gratifying. May I not take this occasion to say that the departments of the Government are ready to cooperate in every way that may be required, and that the heads of the departments most immediately concerned are now, at my request, actively engaged in considering the best methods of cooperation? " Representatives of Government bureaus will be appointed as...
עמוד 413 - Finally, we may add that the entire western half of the Pacific bottom appears to be as mobile as any of the continents of the northern hemisphere, with the difference that the sum of the continental movements is upward, while that of the ocean bottoms is downward. This paper will be published at greater length and with illustrations in the American Journal of Science.
עמוד 509 - The preparation of reports by special committees, suggesting important research problems and favorable opportunities for research in various departments of science. (3) The promotion of cooperation in research, with the object of securing increased efficiency; but with careful avoidance of any hampering control or interference with individual freedom and initiative. (4) Cooperation with educational institutions, by supporting their efforts to secure larger funds and more favorable conditions for...
