WILD ANIMALS IN CAPTIVITY 
affectionate embrace, at the same time uttering sounds 
of gratification and satisfaction. In a few seconds they 
rose up on their legs and, standing as erect as their form 
would allow, with their arms raised above their heads, they 
grasped each other’s front paws and gave vent to loud 
yells and howling screaming barks, at the same time look- 
ing upwards as if returning thanks to some invisible friend. 
The house resounded again and again with the sound of 
their powerful voices. After this performance a more 
minute examination took place. They searched one another 
all over, smelling and gently feeling each other from top 
to toe, then gave each other another hearty hugging and 
uttered a more gentle vocal congratulation. Thus the two 
strangers made friends and sympathized with each other, 
wonderfully like human beings. 
chimpanzee’s intelligence. 
A chimpanzee which I tried to educate made miserable 
attempts to thread a large packing-needle, and also to 
unlock or lock a door. The nearest approach to success 
was in the attempt to spin a humming-top, but this was 
only accomplished with great assistance. A chimpanzee 
in the Gardens was compelled always to use a spoon, 
which he did with considerable difficulty. This natural 
want of intelligence in the chimpanzee prevents his learn- 
ing, and it is easier to teach a dog, who, from his superiority 
of brain power and instinct, more readily understands 
every action and word of command. 
Our chimpanzee was very proud of a fine showy dress, 
allowing himself to be measured, and showed every in- 
telligence towards the dress-maker to have a scarlet 
velvet dress fitted on.
