*nuch harder 5 it did heat the Drill ia palling *. And there may be 
ibme reafon for that too vie. that fince the Progreflion of molt 
Quadrupeds chiefly depends upon a more frequent motion of the 
Fore than Hind Limbs, it does much more here, where the Head 
is proportionably more heavy than in other Animals. And this 
perhaps is the reafon too, why the Fore Limbs in this Animal 
are brought lo far forward •, for meafuring in a ftreight Line from 
the Humerus above to the Carpus below, and bringing another 
Line direXly backward at the Articulation betwixt the Humerus 
and Cubitus , from the perpendicular Line before to the point of 
the Olecranon behind, it is 20 Inches \ which is the reafon why 
fome believe my Engraver has made the fore Limbs of theScele- 
ton to bend too much at the Articulation. The Bones of the 
Carpus are pretty folid, and by Perforation they feem only to 
have a little fpongiofity about the middle: All the re It of the 
Bones of the fore Foot are fpongy. The jijlragalus, Os Tfavi~ 
cularey and Off a Cuneiform a, are more folid j but the Talus and 
other Bones of the hind Foot fpongious. The Spine was fpongy, 
, as is ufual * the Offa lnnominata of a middle Confiftence^ and the 
Scapula very thin, but folid toward its Neck. I cannot pofitively 
determine the Cavities for the Marrow, nor quantity of it-, but 
by comparing the Dimenfions with the Weight and fmall quan- 
tity of fat to be feen at the boiling, we may fuppofe it not to 
have been much in this Animal : 1 know not how it may be in 
others of this Species. 
I mull not forget to tell you, that when I weighed the Bones, 
it was immediately before they were joined ; fo that their weight 
was much diminiih’d, in refpeft of what it was when they were 
newly boil’d. The weight is §16. to 1 lb. and the meafure, 
according to the Englijh Yard, -32 Inches to a Foot, and 12 
Lines to an Inch. 
And thus, Sir, I have finifh’d tbefe my Weak Endeavours : The 
Undertaking, I doubt, will feem bold to fome, and rafh to o« 
thers, and the Performance mean. But the many Obligations you 
have laid upon me, and the frequent Marks of Efteem I have 
received in your feveral Letters, made me pafs over all Obltacles, 
Reflexions, and Difconragements, when to ferve you and your 
Honourable Society was my only Defign. I have rather cho- 
fen to addrefs you in a plain and common Stile, than give the 
iieaft fufpicion oLDilingenuity in a finer Language-, efp.-cially
