donta ), Cachalot ( Physeter ). The skulls of these animals are in the 
court yard. 
The family of Porpoises (Delphinid^), which have a moderate or 
small head, and an elongated smooth body, as the dolphins ( Delphinus ), 
which have conical jaws and teeth, the porpoises, ( Phoccena ), which have 
a shorter head and compressed teeth, the Hyperodons, which only have 
a few teeth; all these have tapering front limbs, while the susuk (P/a- 
tanista ) have triangular truncated limbs, an elongated beak, with com¬ 
pressed teeth, and the bones of the skull bent over the forehead, so as 
to form an arched cavity. 
In the other families the skin is more or less homy, and the lips 
always furnished with rigid whiskers; the teeth are flat topped. The 
Manatees (Manatid^e), which have eight grinders in each jaw, and the 
tail rounded at the end. The dugongs ( Halicorim:), which have only- 
three or five grinders in each jaw, and the end of the tail truncated or 
two-lobed. The larger specimens of the seals, the whales, dolphins, &c., 
are for the present put over the Cases in this room. They range thus •.

The fifth order, or hoofed beasts, (Ungulata, Cases 32—53,) 
have their feet formed for walking on the earth; their toes are large 
and expanded at the end, protected with hoofs or large conical claws. 
Their teeth are irregular, the cutting and canines are often wanting in 
one or both jaws, and the grinders are all similar, with a flat or cross 
ribbed crown, and they are often destitute of roots; sometimes these 
teeth also are wanting. 
This order is divided into two great groups, according to the form of 
the toes; the first having two toes larger than the rest, called cloven 
footed beasts, and the others having three or more toes of nearly equal 
size. 
The cloven footed beasts ( Furcipeda ) have the two middle toes of the 
feet large, equal, separate, or united together and covered by a horny 
case called a hoof; the two bones of the metacarpus are united together 
into a cannon, and the cutting teeth and grinders are separated by a 
vacant space; the teats are always in the groin. 
The family of Oxen (Bovidje, Cases 32—50) have the two large 
middle toes separate, each covered with a hoof; the lateral toes are 
rudimentary. The head is generally furnished with horns, especially 
in the males, which they use as their means of defence, and the gullet 
is furnished with two large cells, just before the two-celled stomach, in 
which the food is placed, that it may be masticated at leisure. 
In many, the processes of the frontal bone, called horns, are covered 
with a permanent case. They have no cutting teeth in the upper and 
eight m the lower jaw 7 ; their upper lip is entire, as the oxen, antelopes, 
goats, and sheep.
