Furthermore, the station should be permanent, since for many 

 kinds of work it would be essential to have intimate knowledge 

 of the life history and descent of an individual. With the 

 lower primates, a generation might be obtained in from two to 

 five years; with the higher, not more frequently, probably, than 

 from ten to fifteen years. It therefore seems not improbable 

 that the value of the w6rk done in such a station would con- 

 tinue to increase for many years and would not reach its max- 

 imum short of fifty or even one hundred years. 



A staff of several highly trained and experienced biologists 

 would be needed. The following organization is suggested as 

 desirable, although, as indicated below, not necessarily essential 

 in the beginning: (1) An expert especially interested in the 

 problems of behavior, psychology, and sociology, with keen ap- 

 preciation of practical as well as of theoretical problems; (2) an 

 assistant trained especially in comparative physiology; (3) an 

 expert in genetics and experimental zoology; (4) an assistant 

 with training and interests in comparative anatomy, histology, 

 and embryology; (5) an expert in experimental medicine, who 

 could conduct and direct studies of the diseases of man as well 

 as of the lower primates and of measures for their control ; (6) an 

 assistant trained especially in p9,thology and neurology. 



To this scientific staff of six highly trained individuals there 

 should be added a business manager, a clerical force of three 

 individuals, a skilled mechanician, a carpenter, and at least 

 four laborers. 



The annual expenditures of an institute with such a working 

 staff, would in southern California, approximate fifty thousand 

 dollars. It would therefore be necessary that it have an en- 

 dowment of approximately one million dollars. 



In the absence of this foundation it would, of course, be pos- 

 sible to make a reasonably satisfactory beginning on the work 

 which has been outlined in the following less expensive manner. 

 A working plant might be established, on ground rented or 

 purchased at a low figure, for about ten thousand dollars; the 

 salary of a director, assistants, a clerical helper, and combined 

 mechanic and laborer might be estimated at the same figure; 

 the cost of animals and of maintenance of the plant would 

 approximate five thousand dollars. Thus, we should obtain as 

 an estimate of the expenditures for the first year twenty-five
