From the March 9, 1910 Brooklyn Daily Eagle:

“Washington–Eleven monkeys have been sent to the government hospital for the insane, though the little ‘forest men’ are sound mentally and healthy. Fresh from George Washington University, where their association was with professors and students of psychology, by whom their faculties for perception and sensation were pronounced to be more keen than those of the average man, the simians are now to be subjected to close scientific scrutiny in order that the savants may learn what effect may follow confinement among insane persons.”
