also obliged me with a sketch, which he had made, chiefly to mark 
the curvature of the tusk, which appeared to him as very extraordinary. 
From this sketch, it appears to have formed nearly four-fifths of a 
circle. 
On the other hand, the fragments of a pretty large tusk, which I 
have from Essex, are sufliciently long to show, that the degree of 
curvature could have very little exceeded that of tusks in general. 
Another specimen from Essex, a portion of the smallest end ot a 
pretty large tusk, laterally flattened, appears to have been full as 
straight as recent tusks generally are. The same was observable of 
another portion from Essex, which I presented to a friend. A very 
small tusk, from the same place, is particularly straight : this, how- 
ever, belonged to a very young, and most probably to a female animal. 
From the preceding observations it appears then, that the fossil 
elephantine remains, notwithstanding their resemblance in some re- 
spects to the bones of the Asiatic elephant, have belonged to one or 
more species, different from those which are now known living. 
This circumstance agrees with the facts of the fossil remains of the 
tapirs and rhinoceroses, which appear to have differed materially from 
the living animals of the same genera. The remains of elephants 
obtained from Essex, Middlesex, Kent, and other parts of England, 
confirm the observations of Cuvier, that these remains are generally 
found in the looser and more superficial parts of the earth, and most 
frequently in the alluvia which fill the bottoms of the vallies, or which 
border the beds of rivers. They are generally found mingled with 
the other bones of quadrupeds of known genera, such as those of the 
rhinoceros, ox, horse, &c. and frequently also with the remains of 
marine animals.
