It has been stated by travelers that when the weather be¬ 
comes cold or rainy, the orang wraps itself in large leaves, 
by way of protection. It is curious to observe that this 
habit is carried into captivity, for if a blanket is left in the 
cage, the animal will at once envelop itself so completely 
that nothing can be seen of it but its bright eyes peering out 
from under the folds. 
The Dyaks of Borneo call the orang by several names, the 
most common being “Mias.” The old males, to whom a 
huge callosity which grows out on each cheek, together with 
a long red beard which covers the chin and throat, gives a 
hideous appearance, are known as “ Mias-papan.” 
The specimens of these apes which are usually exhibited 
in zoological collections, are young, ranging from three to 
six or eight years old. Their development is slow, as it is 
not supposed that they reach maturity until about fifteen 
years of age. When old they generally become morose and 
vicious in disposition. 
The Gibbons are least in size and lowest in organization 
of the anthropoid apes; they inhabit parts of India, Malacca, 
and many islands of the Malayan region. They vary so in¬ 
terminably with age, sex, and locality that it seems hopeless 
to attempt to class them into species. Of those well known, 
the Active Gibbon (. Hylobates agilis) and the White-handed 
Gibbon (. H '. lar ), have been shown in the collection. 
Among the monkeys of the Old World which are commonly 
to be found in the building, is the Entellus or Sacred 
Monkey ( 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 privilege 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 
under the native rule in India, capital punishment was inflicted 
for its destruction. 
Other rare species are the Mitred Monkey ( S . mitratus'), 
the Moor Monkey ( S . maurus ), and the Purple-faced 
Monkey (S. cephalopterus ). 
The Vervet Monkey {Cercopithecus lalandi), the Green 
Monkey (C. callitrichus ), the Patas or Red Monkey (C. 
ruber), the Lesser White-nosed Monkey (C. petauristd ), the
