In the last twenty years. Dr. Robert M. Yerkes of Yale University, with a stafT of assistants, has been studying intensively the behavior of these disconcert- ingly "almost human" apes, maintaining for the purpose a considerable colony of them under constant observation in Florida, and another smaller group at New Haven, Connec- ticut. His painstaking and arduous investigations are adding very much to our accu- rate knowledge of the dawn of intelligence and of the an- cestral sources of human be- havior.
