ANTHROPOID APES 285 
course still more sensitive to corporal punishment. Moritz, 
on the other hand, is a more thick-skinned and robust animal : 
not so easily controlled by either mode of reproof. The keeper 
finds it necessary, therefore, when he has to be made to do 
something, to keep at hand a stick on which the ape’s atten- 
tion may constantly fall. 
When, for instance, he has

sanguine sort of individual, 
and very mercurial in tem- 
perament, changing in a 
moment from the brightest 
gaiety to the deepest de- Bilpleasc, walter! 
spondency, and vice versé. He can never keep his atten- 
tion fixed on one thing for more than a moment or two, but 
is constantly flying off at a tangent to some new idea which 
has taken his fancy. His latest craze has been learning how 
to ride a bicycle. It took him only a few weeks to perform 
this feat, and he now rides astonishingly well. He appears to 
find it great fun, moreover, and pedals about with such vigour 
in my animal park that the trainer is hard put to it to keep up 
with him. 
For looking after these anthropoids I have secured a
