the study of the anthropoids. In August, 1915, Doctor Rothmann died.
Presumably, the station still exists at Orotava in the interests of
certain psychological and physiological research. So far as I know,
there are as yet no published reports of studies made at this station.
It seems from every point of view desirable that American psychologists
should, without regard to this initial attempt of the Germans to provide
for anthropoid research, further the establishment of a well equipped
American station for the study not only of the anthropoid apes but of
all of the lower primates.

In the early months of the war while I was making every effort to obtain
reliable information concerning conditions in the Canary Islands, I
received an urgent invitation from my friend and former student, Doctor
G. V. Hamilton, to make use of his collection of animals and laboratory
at Montecito, California, during my leave of absence from Harvard. This
invitation I most gladly accepted, and in February, 1915, I established
myself in Santa Barbara, in convenient proximity to Doctor Hamilton's
private laboratory where for more than six months I was able to work
uninterruptedly under nearly ideal conditions.

Doctor Hamilton without reserve placed at my disposal his entire

investigation. I cannot adequately thank him for his kindness nor make
satisfactory acknowledgment here of his generous aid. Thanks to his
sympathetic interest and to the courtesy of the McCormick family on
whose estate the laboratory was located, my work was done under wholly
delightful conditions, and with assistance from Ramon Jimenez and Frank
