THIRD ROOM. 
The Upright Cases round this Room contain, for the present, the 
Handed and Glirine Mammalia, ant} the Table Cases the continuation of 
the arrangement of the Radiated Animals, those which form corals. \ 
The first order of Mammalia, called Primates, because they are 
considered as the most perfect animals, is placed in this room. They 
are characterized by having distinct and well defined cutting, canine, and 
grinding teeth, placed in a regular uninterrupted series. The front, 
and most generally the hinder extremities, are in the shape of a hand, 
having the thumb placed lower down than the rest of the fingers, so 
that it can be opposed to them, which enables the animals to grasp 
bodies with great security, a matter of great importance in climbing 
animals. Their teats are placed on their chest, and the male organ is 
free and pendulous. Their brain is much more developed than in 
most other beasts. Linnaeus and some other naturalists have included 
the genus Homo (Man) in this order. But a prominent zoological 
character which separates this genus from the rest of the animals which 
are referred to the order, is in the fore limbs alone being furnished 
with an opposable thumb, w ? hile the great toes of the hinder limbs 
are placed on the same level as the other toes, and are not opposable 
to them. 
The family of Apes ( Simiadce, Cases 1—23) have the same number 
(thirty-two) of teeth as man, viz. two cutting teeth, one canine, and 
five grinders, on each side of the upper and the lower jaw. The fore 
and hind feet are furnished with an opposable thumb, the septum 
between the nostrils is thin, and the rump is generally protected by 
a hard naked skin; they are usually furnished with a tail, and they 
have pouches on the sides of the mouth between the cheeks and the 
jaw r s, in which they place their food for security. They are entirely 
confined to the warmer parts of the Old World, especially Asia and 
Africa, a single species alone having been naturalized in Europe on the 
Rock of Gibraltar. 
The true Apes ( Simiana , Cases % ) have no tail, and bear the 
nearest resemblance to the human form, as the Pongo or Chimpanzee 
{Troglodytes) of Tropical Africa; the Orang ( Simla); the Siamang 
{Siamanga); and the Long-armed Apes ( Hylobates ) of Tropical 
Asia and the Islands of the Asiatic Ocean. The Chimpanzee and the 
Orang w T alk on the outer edge of the foot and back of the fingers of 
the hand, and not on the sole as the other monkeys ; they have 
moderately long, and the other genera very long arms. They grow to 
a very large size, are playful and good tempered when young, but as
