ANTHROPOID APES 291 
from the expression in his eye, what sort of a mood he is 
in. His memory, like that of the orang, is excellent. Some 
time ago, after I had been travelling for some time and had 
just returned, I went to see him in his cage. The moment 
I set foot in the ape-house he welcomed me with loud shouts, 
and would not be pacified until I had gone into his cage, and 
taken him in my arms and fondled him. 
In June, 1908, Lieutenant Heinicke of the German army 
brought over with him from Kamerun a young gorilla which 
was taken round to be introduced to my three anthropoids. 
Their meeting was very interesting and unique. The gorilla 
displayed only a moderate interest in his three cousins, taking, 
in plain words, very little notice of them. They, on the other 
hand, were immensely interested and excited. The chim- 
panzee gave vent to his feelings in loud yells ; and thrusting 
his arms through the bars tried to draw the gorilla towards 
him. When he failed in this attempt, he became indignant, 
and proceeded to pelt the stranger with sand and stones. 
The orangs likewise endeavoured to reach the gorilla through 
the bars; and, when they failed, expressed their emotions, 
each according to his kind. Jacob followed the example of 
the chimpanzee and began throwing stones; while Rosa’s 
excitement brought on a fit of vomiting, so that the whole 
scene was indescribably droll. The scene was in other ways 
almost unique. For here there were gathered together in 
one spot representatives of the three species of animals most 
nearly akin to man. 
Lieutenant Heinicke, who had brought the young gorilla 
to Europe in the society of two negro boys, hoped to be able 
to keep this rare animal alive for a long time. Over in 
Kamerun he had kept it for more than a year, during which 
time it had enjoyed unbroken health and become a general pet 
of the station. He hoped to be able to overcome the diffi- 
culty of lack of society by providing the two negroes as con- 
stant associates for the animal. When the ape first arrived 
at my animal park he was much weakened with his long sea
