4. The fuppofed Elephant’s tufk, which was 
brought from Siberia by Mr. Bell, and prefented to 
Sir Elans Sloane, and of which we have a defcription 
and figure in the Memoirs of the Academy of Scien- 
ces at Paris (An. 1727. page 309), is evidently twifted 
like the tulle of the incognitum , and not at all 
like any Elephant’s tulle which I have ever feen. 
This proof will have confiderable weight with thofe 
who will take the trouble to examine that tufk in 
the Britilh Mufeum. 
In the laft place, it may be obferved, that as them- 
cognitum of America has been proved to have been 
an animal different from the Elephant, and probably 
the fame as the Mammouth of Siberia 3 and as grinder 
teeth like thofe of America have been dug up in vari- 
ous other parts of the world ; it flhould feem to follow* 
that the incognitum in former times has been a very 
general inhabitant of the globe. And if this animal was 
indeed carnivorous, which I believe cannot be doubt- 
ed, though we may as philofophers regret it, as men 
we cannot but thank Heaven that its whole generation, 
is probably extindf.
