Abstract

IN honour of the centenary of the establishment of the Physical and Agricultural Society at Königsberg, Dr. Walter Simon has given the Society the sum of four thousand marks to be offered as a prize for a work on the subject of plant or animal electricity, presenting either fundamentally new aspects, or dealing with the physical cause of organic electricity, or its importance upon life in general, or upon certain functions. The competition is open to every one. The works presented may be printed or written in German, French, English, or Italian, and must be sent in before December 31, 1900. Works which are published before the end of next September will not be admitted to the competition, as the intention is to give the prize for works which are comparatively recent at the time of the award. Should no work of sufficient merit be presented the prize may be withheld, or two prizes of five hundred marks each may be awarded. The Committee appointed to make the award consists of Profs. W. Pfeffer, B. Frank, W. Kühne, E. Hering, and L. Hermann, with power to add to their number. Further information concerning the prize may be obtained from the President, or the Secretary, of the Physikalisch- ökonomischen Gesellschaft, Königsberg.
