Proceedings.
IJ- F. I.,
[ahrbuch der Elektrocheraie. Berichte fiber die Fortsehritte des Jahres, 19oo. Von Dr. W. Nernst und Dr. W. Borchers, VII, Jahrgang. Halle a/S. Verlag yon Wilhelm Knapp, 19Ol.
4to pp. 496.
The yearbook of progress edited by Drs. Nernst and Borchers has for years been the only source of reference to the progress of the electrochemical industries available to students of this branch of applied electricity. It is simply invaluable and indispensable to all who are interested in the electrolytie and eleetrothermte industries. W.
The Indudion Motor. A short treatise on its theory and design, with numerous experimental data and diagrams. By B. A. Behrend, M.I.C.E., etc. 8vo, pp. IO5. New Y o r k : Electrical W o r l d and Engineer, Inc., N. D. (Price, $t.5o. ) The author justifies the writing of this treatise by the fact that the induction motor has thus far received little attention from the authors of electrical literature--the few whose experience and knowledge of the subject would entitle them to speak authoritatively on this subject being deterred from publishing for commercial reasons. The author treats the subject under eight chapter heads, respectively, as follows: I. The general alternating-cixrrent transformer; II (a) the character of the magnetic field in the polyphase motor ; (b) the formulm for the 3-phase-current motor ; Ill, the short-circuit current and the leakage factor ; IV, the leakage factor ; V, design of a 3-phase-current motor for 200 horsepower ; JVI, the single-phase motor ; VII, calculation of a single-phase current motor; VIII, the polar diagrams of the general alternating-current transformer. Appendices. W.
Franklin Institute. [Proceedings o f the slated meeting held Wednesday,.December 18, z9oi. ] HALL OF THE FRANKLIN INSTITUTE, PHILADELPHIA, December i8, 19Ol. President JOHN BIRKINBINE in the chair. Present, 204 members and visitors. Additions to membership since last month, 17. The Secretary reported the gift of a portrait in oil of the late Joseph Harrison, Jr., well known in connection with the development of the locomotive engine, the equipment of the Russian railways, and safety steam-boiler design. The donor is Mr. H e n r y Harrison Suplee. The special committee appointed at the previous meeting to consider and report upon certain preambles and resolutions " t o promote commerce," offered by Prof. Louis M. Haupt, made the following report :
