II. Objeryations upon the Callus of the Hands and 
Feety by the fame curious Gentleman, » Tranflated 
hy John Chamberlayne, 
I N the Month of 1719. feeling an acute 
Pain in one of my Feet, at the Joint between the 
Foot and the little Toe, which I imagined to proceed 
from the more than ufual Thickneft of the Callus 
or hard Skin, upon that part ; I caufed my Servant, 
partly with his Nails, and partly with a Penknife, to 
take ofF that hard Skin, and let it fall upon a blue Pa- 
per, that I had let my Foot upon. 
This Callus^ or hard Skin, was compos’d of little 
fcaly Shivers lying upon one another, and the whole 
Piece was as large as a fmall Nail of a Man’s Hand. 
I view’d the faid Shivers thro’ a Microfcope, but 
cculd not latisfy my felf, becaule they lay lb irregularly 
on each other. 
Moreover, I took a little Bit of the aforefaid hard 
Skin, laid it on a clean Glals-Plate, fteep’d it in pure 
Rain-Water, and gently dividing it with a Piece of a 
Quill, I was amazed to lee into what a vail Number 
of Particles it feparated, and that with as much Rea- 
dinels, as if they had never been join’d.
