INTESTINAL FEVER AND ULCERATION. 275 
and demeanour, which seemed in him, as in many a human 
being, to cover much lack of thought. 
The only times when I had some doubt about this matter, and 
thought that he was playing the hypocrite, and understood a 
great deal more than he pretended, were, when I have seen him 
sitting in his quiet observant way, his eyes wandering from one 
to the other of us, as we were talking, and perhaps talking 
about him ; and I have fancied that there was a pout at the 
person who was finding fault with him, and a half-smile for his 
advocate. At all events, he had not, in the slightest degree, 
the power of speech. He could scream loudly enough, and not 
unlike a child ; but it was only a difference — a considerable one 
certainly — of intonation in the grunt, that marked his appro- 
bation or his displeasure. 
His food consisted of fruit, milk, biscuits, and, now and 
then, a little cooked meat; his favourite food was raw ripe apples, 
which were always carefully pared for him, and which he would 
give to his keeper for that purpose. He began afterwards to 
be very fond of sugared tea, and occasionally he was clamour- 
ous for the porter of the keepers. He would take the cup in 
both his hands, and lift it to his lips, and drink precisely in the 
same way that the human being would, except that his lips pro- 
truded considerable farther. 
When occasionally he was put out of temper, he would utter a 
hoarse guttural sound, and protrude his lips, and look intently, 
and with the perfectly natural expression of anger, at the offender ; 
and sometimes he would try to seize the hand of the offender 
and endeavour to bite it : but his anger was a passing cloud, 
and he was soon the same quiet, melancholy, or harmlessly play- 
ful creature as before. 
He exhibited no aversion to any of the quadrupeds that were 
occasionally brought within his view. It has, however, been said, 
that “ the monkey tribes have an instinctive fear of the larger 
kinds of snakes, to which they occasionally fall a prey : it was con- 
sidered worth the trial to ascertain whether, in an animal so 
young, and which most probably had never seen a formidable 
snake, this feeling was fairly displayed. Accordingly a large 
snake was shewn to him, on seeing which the chimpanzee was 
at once filled with terror, and hid himself in a corner. The lid of 
the basket into which the snake was put was then closed, and 
an apple placed upon it ; and though the animal desired the 
fruit, it would not venture near the lurking-place of its dreaded 
foe, but by actions and gestures, too plain to be misunderstood, 
expressed its consternation ; — nothing, in fact, would induce it 
to approach the basket. This, with the snake, was at length
