Page 125 - Measurements of the effect of pressures to 12000 kg/cm2 on the thermal conductivity of 1 1 metals have been made by one or the other of these methods. The effect may be either positive or negative, and is more often negative than positive. In only two cases, lead and tin, does the Wiedemann-Franz ratio increase under pressure; for the other metals it decreases, and sometimes by large amounts. In addition to the metals, the pressure coefficient of thermal conductivity of petroleum ether has been measured....

The two sets of points were obtained with the same specimen, but with different positions of the electrodes. The points shown by the crosses are the observed points corrected by the ratio of the total resistance to the resistance of the isthmus. If the effect measured is a genuine departure from Ohm's law, the corrected points...
Page 475 - I deliberately put aside all teachings of theory, because it seemed to me high time that the facts should be examined by a purely inductive process ; that the nugatory results of all attempts to detect the existence of the Eulerian period probably arose from a defect of the theory itself; and that the entangled condition of the whole subject required that it should be examined afresh by processes unfettered by any preconceived notions whatever.
Page 474 - s connection with the Peabody Museum of Harvard University was a long and a close one. From 1888 to the time of his death he was its greatest benefactor. In 1894 he became a Trustee of the Museum and always took the greatest personal interest in the welfare of the institution and its varied activities. His patronage of the Central American work of the Museum covered many sides. He financed and planned annual expeditions to the Maya field, beginning in 1891 and continuing in an almost unbroken series...
