12 TRAITS OF YOUNG CHIMPANZEES 



varieties of monkey, baboons, and one young orang-utan. 

 These animals were observed both in their semi- wild and free 

 condition and in various experimental situations arranged 

 in the investigator's laboratory. The work terminated and 

 the station was discontinued with Dr. Hamilton's removal 

 from California in 1917. 



Prior to the war, certain groups of medical investigators 

 planned the establishment of a breeding station and special 

 laboratories for medical research on the west coast of Africa 

 or an adjacent island. The development of the project was 

 delayed. In 1922 the Pasteur Institute, under the direction 

 of Dr. A. Calmette, founded a primate station primarily for 

 medical research at Kindia, French Guinea. 



At Havana, Cuba, for more than a decade Madame Rosa- 

 lia Abreu has kept on her estate a collection of monkeys and 

 anthropoid apes. At present she has some 75 animals, 

 including several types of monkey, baboons, mandrills, 

 gibbons, orang-utans, and chimpanzees. Thus far, apart 

 from certain anthropological observations (10) and the 

 studies of daily life made by Madame Abreu, these animals 

 have not been utilized for scientific purposes. The writer 

 has been able during the summer of 1924, by the generous 

 invitation of Madame Abreu, with the support of the Carnegie 

 Institution of Washington and the cooperation of assistants, 

 to initiate certain studies of the behavior, mental life and 

 structural characteristics of animals in this unique collection. 



Aside from the scattering specimens of anthropoid ape 

 found in zoological parks, there are several in the possession 

 of persons who are both able and eager to advance our 

 knowledge of the primates. Notable contribution to in-

 gorilla, G. beringeri, which occurs in the Lake Khivu region
