2. Physical Environment: Responses to altered environmental situations 
demanding changes in locomotor habits, resting habits, spacing behavior, sexual 
behavior, aggressive behavior, etc. 
3. Dietetic: Responses to wide range of food and feeding patterns, with par- 
ticular reference to changes in the skeleton. 
4. Social Organization: Study of ideal group size in differing captivity situations 
and its relation to cage size. 
5. Diversionary: Investigation of the value of “spare time” activities in the 
general welfare of the captive. 
An essential correlate of this program will be a field investigation 
of certain basic behaviors of primates in the wild, e.g., diet, locomo- 
tion, climatic tolerance, resting posture, etc. (see “Field Studies” 
below). Captivity studies are clearly a long-term project that will 
be based both in the United States and the United Kingdom. In- 
formal talks already have been held with a pharmaceutical research 
center in England that is interested in the possibility of setting up 
primate research of this general nature on its estates in the South 
Midlands. 
Freip stupi1Es.—Field studies of free-ranging primates are pivotal 
to the systematics, captivity, and population studies discussed above, 
and they will constitute an important part of the program. 
It is hoped that it will be possible to establish junior and senior 
field-study studentships for graduate as well as post-doctoral scien- 
tists. Senior studentships normally would be held for five years and 
the junior appointment for three years. This period will ensure that 
the post-doctoral worker will, on the completion of his field work, be 
available to contribute to the systematics and captivity research 
projects and to the teaching and other activities of the Primate 
Biology Program. A policy might be adopted whereby the holders of 
these two studentships would act as senior and junior members of a 
field-research team. 
The possibility of establishing a field primate research training 
program at the Smithsonian Tropical Research Institute, Barro 
Colorado Island, Panama, in connection with the award of the junior 
field-study studentship will be investigated. 
FUNCTIONAL ANATOMY.—Collection of data on sound biometric 
principles is still an important part of primate biology. There is no 
better example of this type of work than that provided by Adolph 
Schultz, whose lifetime study of growth and variability in the skeletons 
of higher primates has contributed so much to our knowledge. Statis- 
tical techniques such as that of multivariate analysis will in the future 
provide an even better method of assessment of such data; further- 
more, it is expected, as a fall-out from such projects as systematics 
research, that new information on the anatomy and physiology of 
primates will become available. The field of primate anatomy has
