’Tis not above two Inches long. The parts of the Head, 
Chefl, and Limbs are all entire, but not perfect. For the 
extremities of the Bones of the Arms and Leggs, are at 
both ends plainly cartilagineous. They are in thicknefs 
like a Taylors Hitching Thread. Given by Thomas Povey

It may poflibly be conceived by fome, That the Bones, 
at leaH fome of them, are hard at the firfl 3 as Salts and 
other like CryHallizmg Bodies are as hard upon the very 
firfl inftant of their fhootmg, as they are when grown into 
great Cryflals. But it is fo far evident, that all the Bones 
are foft at the firfl, that I am of opinion, That originally 
they arc a Congeries of Fibers os fibrous Veflels, as true as 
any other in the Body 3 which by degrees harden into 
Bones: even as the inmofl VefTelsina Plant, do in time 
harden into Wood, (a) And that as in a Plant, there are 
fucceflive additions of Rings or Tubes of Wood, made 
out of Yeffels: So in an Animal, it feems plain, That 
there are additions fuccefflvely made to the Bones out of 
the Fibrous parts of the Mufcules; efpecially, thofe whitefl 
Fibers which run tranfverfly, and make the flamen or warp 
of every Mufcule. So that as in the Barque of a Plant, 
part of the Veflels are fuccefllvely derived outward to the 
Rind\ and part inward to the Sap, which ffterwards be¬ 
comes hard mod. ( b ) So in the Flefh of an Animal, part 
of the white tranfverfe Fibers are fucceflively derived to the 
Skin (of which this chiefly confifls) and part of them in¬ 
wardly, making Hill new Periofteums one after another, as 
the old ones become fo many additions to the Bones.
