A SOCIETY FOR ANIMAL PSYCHOLOGY 



ROBERT M. YERKES 



In September, 191 2, there was established in Elberfeld a 

 Society for Animal Psychology, the chief purpose of which is 

 to pre mote the invest gation of the mental life of the mammals, 

 and especially of dogs, apes, and elephants. It is hoped by the 

 founders that an Institute for Experimental Animal Psychology 

 may be established and that numerous investigations may be 

 encouraged in various ways by the Society. 



The organization consists of members, fellows, and founders. 

 Members pay no dues ; fellows pay eight marks per year ; and 

 founders make a single contribution of at least one thousand 

 marks. 



The officers of the Society are Prof. H. E. Ziegler, Stuttgart, 

 President; Dr. P. Sarasin, Basel, Vice-President; Karl Krall, 

 Elberfeld, Secretary; Geh. Kommerzienrat Aug. Freih. von der 

 Heydt, Elberfeld, Treasurer ; and the following directors : Dr. 

 R. Assagioli, F orence ; Prof. Dr. H. von Buttel-Reepen, Olden- 

 burg in Gr. ; Prof. Dr. H. Kraemer, Hohenheim-Stuttgart ; 

 Prof. Dr. A. Besredka, Paris; Prof. Dr. Ed. Claparede, Genf; 

 and Dr. William Mackenzie, Genoa. 



The Society has already begun the publication of proceedings, 

 "Mitteilungen der Gesellschaft fur Tierpsychologie," under the 

 directorship of Professor Doctor H. E. Ziegler, Stuttgart. The 

 first number of the first volume appeared in 191 3. The publica- 

 tion is to appear quarterly and to be sent free of charge to fellows 

 of the Society. 



The first number contains, in addition to an announcement 

 of the Society for Animal Psychology and a list of the members, 

 two brief articles concerning the trained horses of Elberfeld. 

 In the first of these articles, explanations by eminent authorities 

 of the behavior of Mr. Krall 's thinking horses are offered, and 

 in the second, Mr. Krall himself presents an account of the 

 behavior of the blind horse, Berto.
