M. Cuvier proceeded, with patient assiduity, to trace out the remains of 
the other parts of these animals, and his researches were amply repaid. 
The structure of the hind-leg was the first object of inquiry. 
Besides other minute peculiarities in the form of each particular 
bone, dependent on the general structure of the limb, he found that 
Anoplotherium commune had, to the hind-leg, two perfect toes articu- 
lated with two metatarsal bones, which remained distinct and separate 
through life. This species of structure is unknown among living ani- 
mals ; since the ruminating animals, and even the camel, which agrees 
with this animal, in having a separation of the scaphoid and cuboid 
bones, have their metatarsal bones united through their whole length, 
in one piece, forming the cannon-bone, and in which, however, its 
double origin is not concealed. 
The structure of the hind-foot alone, therefore, would have been 
sufficient, if we had been ignorant of the peculiarities of the head, to 
have shown, that this animal was of a species at present unknown. 
From the structure of this part it may also be seen that this animal 
agreed in one respect with the pachydermata, and in another with the 
ruminants, with which it is connected by the medium of the camel. 
From the thickness and shortness of these bones, considered as to 
their length, this animal may be concluded to have been very large 
proportioned to its height — a conclusion which will be found to be 
warranted by the proportions of the bones of its legs and thighs. 
The investigation respecting the hindfeet of Anoplotherium medium , 
was still more satisfactory than even that respecting A. commune ; 
since a left foot, forked, and having two distinct metatarsal bones, was 
found almost entire, but much smaller and thinner than that already 
described. This foot was of a size which would have agreed with that 
of a sheep of a middling size ; and though belonging to the same 
genus, appeared to warrant the conclusion, that the animal must have 
been taller and thinner, in proportion, than the preceding species. 
Anoplotherium minus appeared, from an astragalus, which certainly
