liquely and their mammae are situated on the chest. We may 

 also add that their brain resembles that of man very much, and 

 each hemisphere consists of three lobes, the posterior of which 

 covers the cerebellum; and their abdominal viscera scarcely 

 differ from ours. 



3. The order of Quadrumana is divided into three families : 

 Monkeys, Ouistitis, and Makis. The following table exhibits a 

 synopsis of the most prominent distinctive characters of these 

 three groups.

4. Monkeys are animals of middle or small stature, whose 

 heads are almost always rounded, the muzzle moderately elon- 

 gated, the neck short, the body light, and extremities slim, 

 (Plate 1, fig. 4. to 9.) They are covered with long silky hair; 

 nevertheless, their resemblance to marr is very considerable, and 

 there are some, which when very young, have the facial angle 

 not much more oblique than that of negroes ; but as they advance 

 in age the muzzle always becomes much more projecting, and 

 with some monkeys, this part of the face is so much developed 

 as to resemble that of the dog. The actions and behaviour of 

 these animals bear a strong analog> eO our own. Many ot 

 them assume with ease an almost vertical position, particularly 

 when aided by a stick, as we use a cane, and some walk in this 

 way, but never so firmly as man ; on the contrary they are admi- 

 rably organized for climbing from branch to branch. The length
