are by far the largest in those animals which have serrated 
teeth" Those animals which have continuous rows of teeth, 
have them either situate on both sides of the mouth, as in 
the horse, or else have no fore-teeth in the upper part of the 
mouth, as is the case with oxen, sheep, and all the animals 
that ruminate. The she-goat has no upper teeth, except the 
two front ones. 'No animals which have serrated teeth, have 
them protruding from the mouth ; among these, too, the fe- 
males rarely have them ; and to those that do have them, they 
are of no use ; hence it is, that while the boar strikes, the 
sow bites. No animal with horns has projecting teeth ; and 
all such teeth are hollow, while in other animals the teeth are 
solid. AlP^ fish have the teeth serrated, with the exception 
of the scarus,^^ this being the only one among the aquatic 
animals that has them leveP" at the edges. In addition to 
this, there are many fishes that have teeth upon the tongue 
and over the whole of the mouth, in order that, by the multi- 
tude of the bites which they inflict, they may soften those 
articles of food which they could not possibly manage by 
tearing. Many animals, also, have teeth in the palate, and 
even in the tail ; in addition to which, some have them in- 
clining to the interior of the mouth, that the food may not 
fall out, the animal itself ha^dng no other means of retaining 
it there.

WHICH HAS TEETH. 
The asp also, and other serpents, have similar teeth ; but in 
the upper jaw, on the right and left, they have two of extreme 
length, which are perforated with a small tube in the interior, 
1^ The morse and the dugong are instances to the contrary. 
19 The females of the elephant, morse-, dugong, chevrotin, and mnntjac 
have them, and they are equally as useful as with the male, only, perhaps, 
not so strong. 
20 This is incorrect, unless he merely means ranged in one continuous 
line ; and even then he is in error. 
21 See B. ix. c. 29. This is called the parrot-fish, from the resemblance 
of its upper and lower jaws to the beak of a parrot. 
22 They present this appearance from being worn away at the surface. 
23 Eondelet would read " gula,'' the throat. This, though repudiated 
by Hardouin, is approved of by Cuvier, who justly looks upon the ordinary 
reading as an absurdity. Many fish, he says, and more especially the 
osseous ones, have teeth in the phaxynx.
