aterials. But it is not improbable that even
cooeperative research would prove on the whole more profitable, except
possibly in the case of morphological work, if investigators could
conduct their studies in the institute itself rather than in distant
laboratories. In any event, the idea of cooeperation should be prominent
in connection with the organization of a research station for the study
of the primates. For thus, evidently, scientific achievement in
connection with these important types of animal might be vastly
increased over what would be possible in a single relatively small
institution with a limited and necessarily specialized staff of workers.

Despite the fact that biologists generally recognize the importance of
the work under consideration and are eager to have it done, it is
perfectly certain that we shall accomplish nothing unless we devote
ourselves confidently, determinedly and unitedly, with faith, vision,
and enthusiasm, to the realization of a definite plan. Our vision is
clear,--if we are to gather and place at the service of mankind adequate
comparative knowledge of the life of the primates and if we are to make
this possible harvest of scientific results count for human betterment,
we must bend all our efforts to the establishment of a station or
institute for research.
