The species inhabits the west coast of Africa near the Equator ; 
its exact range, north, south, and inland, is not satisfactorily- 
determined, but it is probably confined to a limited region 
in company with its larger relative, the Gorilla. 
Divesting the Chimpanzee of the many doubtful, if not 
fabulous qualities with which it has been endowed by imagi- 
native travelers, it remains a huge Ape, attaining in the adult 
male a height of four and a half feet ; devoid of a tail ; pos- 
sessed of a very considerable degree of intelligence, and 
having the ability to walk upright, supporting itself by occa- 
sionally touching its knuckles to the ground or some upright 
means of support. 
They live together in small bands of half a dozen and build 
platforms among the branches, out of boughs and leaves, on 
which they sleep ; their diet is chiefly frugivorus, and they 
are exceedingly mild in disposition, readily becoming friendly 
and seeking the society of man when placed in confinement. 
These Apes are looked on by the natives of their country 
as being degenerate members of their own tribe. The 
native name, “ Engeco, ” means “ hold your tongue,” and 
evidently had its origin in the common belief that they refuse 
to speak purely from laziness, and in the fear that if their 
possession of the faculty should be discovered, they would 
be set to work with the more bipedal inhabitants of the 
same region. The pair in the Garden are believed to be 
about four years old, — their development is slow, as it is 
not supposed that they reach maturity until about fifteen years 
of age. 
Among the Monkeys of the Old World which are usually to 
be found in the collection, is the Entellus or Sacred Mon- 
key {Semnopithecus entellus) of India. This Monkey is held 
in high respect by the human natives of its country, who call 
it Hanuman, after one of their deities, and allow it the priv- 
ilege of stealing, unmolested, pretty much anything to which 
it takes a fancy — a privilege which it soon learns to avail itself 
of on every occasion. Its life is held sacred, and it is a dan- 
gerous thing for a foreigner to incur the displeasure of the 
people by killing one.
