that the length of thofe defcrib’d by him is 8 Foot ; and he, 
with feveral other?, tells us, that there are of them which weigh 
ico Pound and upwards, fome 140, others 150, and thofe he 
talks of were above jco Pound , infomuch, that Tavernier tells us > 
that in the Indies they make Polls of Doors and huge Pales of 
them : And 'tis memorable, which he fays alfo, that the Elephants 
of the lile of Cey'and have no Tusks, but the firft which the Fe- 
male produces: And this we have confirm’d by Mr Knox in his 
Defer iption Relation of this Ifiand, that few of the Elephants there have Tusks, 
"the Tush, and thofe only Males. There is a great debate amoDg Authors, 
whether thefe lhali be call’d Horns or Teeth. Thofe who would 
have them be Horns, fay ill. Becaufe they rife from the Scull. 
2. Becaufe they can be polifh’d, and brought into any form, which 
’tis difficult to do with Teeth. 3. Becaufe they fall off and grow 
up again, which the Teeth of no Animal do, except of Man. 
Such as would have them to be Teeth, tell us, that ’tis peculiar 
to fuch Animals as have the Hoof divided into two, to have Horns ; 
and that Horns are always cavous or fpongy within ; whereas 
thefe are altogether folid. For the firft Reafon, that they rife 
from the Scull, tho’ it be granted, yet it is after a different man- 
ner from Horns •, for they always either adhere to the Scull by a ^ 
certain Articulation, if not cavous, as in Harts, or have a Protu- 
berance ariling from if, and filling up their Capacity, if cavous, 
commonly call’d the Flint. For the fecond, tho’ it be granted 
they can be polifh’d, &c. yet they are not capable of fuch Alte- 
rations, as Horns are by Boiling, or burning in the Fire, fuch as 
being made flexible. Indeed they feem more to agree by their 
Strudure with Teeth •, for they proceed from the Scull, and 
are planted in it per Gomphofm , having in thefe we are fpeaking 
of a large Cavity, about two Inches long, large according to the 
Diameter of the Tusks, at firft, but as they defeend tapering 
gradually, till they terminate in a Point analogous to the Cavities 
in the Roots of the Teeth, and filled up with the fame kind of 
Subftance, whereby they are kept firm in their Places. And as to 
their Strudure, I doubt not but they have been compos’d of a 
mucilaginous Subftance at firft, as Teeth are $ and that after- 
wards they augment by the appofition of feveral Lamina, or Strata , 
according as the Animal encreafes in Years. Hence ’tis, that I 
fuppofe Tcntz*elius his Friend came to be convinc’d, that thofe 
Bones he treats of, were of an Elephant 200 Years Old, by fuch 
Marks as thefe Laming which might bave been taken from the 
Teeth.
