form nor its size will prevent the supposition from being admitted, 
that it may be the tooth of some young animal of the genus Elephas. 
In the family Solipedes, one genus ( Equus ) only can be placed, 
having only one toe and one hoof 
The remains of the horse are only found in the looser alluvial depo- 
sitions. I recollect no instance, in this island, in which its remains 
have been found imbedded in chemical depositions, which possess a 
stony hardness. Thus its remains are frequently found in peat-beds, in 
gravel, loam, See. but not to my recollection, in limestone. From the 
strata in which they exist being frequently contiguous to the surface, 
these remains are often turned up with the plough ; seldom exciting 
much notice, from their not being considered otherwise than as the 
remains of animals of but late existence. This notion has of course 
derived considerable support from the circumstance of these teeth, 
bones, &c. not differing from the living species of the present day. 
Although so exactly agreeing with those of the present species, the 
teeth and bones of the horse are often found mingled with the bones of 
those animals which must have existed at a very distant sera, and even 
sometimes with the remains of those animals which are now unknown 
to us. Thus I have met with them, in this country, in the same 
stratum which has yielded the bones of the great Irish elk, of the 
elephant, rhinoceros, and hippopotamus, and perhaps of the mammoth. 
Cuvier himself saw hundreds of the teeth and bones of horses taken 
from the canal of Ourcq, mixed with those of elephants ; some of the 
former being really petrified. At Canstadt, in Wirtemberg, they are 
found in prodigious numbers, with the bones of elephants, tigers, 
rhinoceroses, and hyeanas : they have also been found, thus associated, 
in Italy, in different parts of France ; and in many of those beds, in 
other parts of the world, in which elephantine remains have been 
found. This, as is justly observed by M. Cuvier, is deservedly inter- 
esting ; since, from the remains of the animals with which they are 
associated, it is probable that they lived before our continents existed 
in their present state.
