CHAP. 98. (43.) DIFFEEENCES OF THE MEMBEES OF MAN FEOM 
THOSE OF OTHER ANIMALS. 
Of all the terrestrial animals, man is the only biped : he is 
also the only one that has a throat, and shoulders, or hu- 
meri,'' parts in other animals known by the name of armi.'' 
Man, too, is the only animal that has the ulna,'' or elbow. 
Those animals which are provided with hands, have flesh 
only on the interior of them, the outer part consisting of sinews 
and skin. 
CHAP. 99. THE FINGERS, THE ARMS. 
Some persons have six fingers on the hands. We read that 
C. Horatius, a man of patrician rank, had two daughters, who 
ibr this reason had the name of Sedigitae and we find 
mention made of Volcatius Sedigitus,^* as a famous poet. 
The fingers of man have three joints, the thumb only two, 
it bending in an opposite direction to all the other fingers. 
Viewed by itself, the movement of the thumb has a sidelong 
direction, and it is much thicker than the rest of the fingers. 
The little finger is equal in length to the thumb, and two others 
are also equal in length, the middle finger being the longest 
of all. Those quadrupeds which live by rapine have five toes 
on the fore feet, and four on the hinder ones. The lion, the 
wolf, and the dog, with some few others, have five claws 
on the hind feet, one of which hangs down near the joint of the 
leg. The other animals, also, which are of smaller size, have 
five toes. The two arms are not always equal in length : it 
is a well-known fact, that, in the school of gladiators belong- 
ing to Caius Csssar,^^ the Thracian Studiosus had the right- 
arm longer than the left. Some animals also use their fore- 
paws to perform the duties of hands, and employ them in 
conveying food to the mouth as they sit, the squirrel, for in- 
stance.

As to the various kinds of apes, they offer a perfect resem-
