CHAP. 108. (48.) THE FEET OF ANIMALS, FKOM THOSE BAVINQ 
TWO FEET TO THOSE WITH A HUNDRED. DWARF3. 
Among insects, those which have hard eyes have the fore- 
feet long, in order that from time to time they may rub the 
eyes with their feet, as we frequently see done by flies. The 
insects which have long hind-feet are able to leap, the locust, 
for instance. All these insects have six feet : and some of the 
spiders have two very long feet in addition. They have, all 
of them, three joints. We have already ^"^ stated that marine 
insects have eight feet, such as the polypus, the ssepia, the 
cuttle-fish, and the crab, animals w^hich move their arms in a 
contrary direction to their feet, which last they move around 
as well as obliquely : they are the only animals the feet of 
which have a rounded form. Other insects have two feet to 
regulate their movements ; in the crab, and in that only, these 
duties are performed by four. The land animals which exceed 
this number of feet, as most of the worms,^ never have fewer 
than twelve feet, and some, indeed, as many as a hundred. 
The number of feet is never uneven in any animal. Among 
the solid-hoofed animals, the legs are of their proper length 
from the moment of their birth, after which they may with 
more propriety be said to extend themselves than to increase 
in growth : hence it is, that in infancy they are able to scratch 
their ears with the hind feet, a thing which, when they grow 
older, they are not able to do, because their increase of growth 
affects only the superficies of the body. It is for the same 
reason also, that they are only able to graze at first by bending 
the knees, until such time as the neck has attained its proper 
■length.

among birds even. 
CHAP. 109. — -THE SEXUAL PARTS. HERMAPHRODITES. 
We have already spoken sufficiently"^^ at length of those ani- 
mals, the naales of which have the sexual parts behind. In 
the wolf, the fox, the weasel, and the ferret, these parts are 
bony ; and it is the genitals of the last-mentioned animal
