MONKEYS — GENERAL INTELLIGENCE.

their offspring by the tail with one hand, correct them 
severely with the other. 
We have already seen that dogs and cats display the 
idea of maintaining discipline among their progeny. 
According to Honzean the sacred monkey of India 
( Semnopithecus entellus) is very clever in catching snakes, 
and in the case of poisonous species destroy the fangs by 
breaking them against stones. 1 
Of the fact that monkeys act in co-operation, many 
proofs might be given, but one will suffice. 
Lieutenant Schipp, in his Memoirs, says : — 
A Cape baboon having taken off some clothes from the 
barracks, I formed a party to recover them. With twenty men 
I made a circuit to cut them off from the caverns, to which 
they always fled for shelter. They observed my movements, 
and detaching about fifty to guard the entrance; the others kept 
their post. We could see them collecting large stones and 
other missiles. One old grey-headed one, who had often paid 
us a visit at the barracks, was seen distributing his orders, as 
if a general. We rushed on to the attack, when, at a scream 
from him, they rolled down enormous stones on us, so that we 
were forced to give up the contest. 
I shall here bring to a close my selections from the 
literature of monkey psychology, because I wish to devote 
a good deal of space to detailing a number of observations 
which have not yet been published. Thinking it desirable 
for the purposes of this work that an intelligent monkey 
should be subjected to close observation for some length 
of time, I applied to Mr. Sclater for the loan of one from 
the collection of the Zoological Society. He kindly con- 
sented to my proposal, and I selected a specimen of Cebus 
fatuelluSj which appeared to me to be the most intelligent 
monkey in the collection. Not having facilities for keep- 
ing the animal in my own house, I consigned him to the 
charge of my sister (who lives close by), with the request 
1 bat she should carefully note all points of interest con- 
nected with his intelligence. Therefore, from the day 
of his arrival till that of his departure she kept a diary.
