Afterwards I took two or three of the faid Particle^ 
of which many were of the Figure of a Weaver’s 
Shuttle, being broad in the middle and pointed 
at each End, with a Line in the middle, like thofe up- 
on the uppermoft or outfide Skin of Fruits, or of our 
Bodies, but generally irregular ; they were very thick 
in Proportion to their Bignefs. I took, I lay, two or 
three of the faid Particles, and laid them on a clean 
Glafs, and put to them a Drop of Water, as large as a 
coarle Grain of Sand, and divided the lame as well as 
I was able ; and viewing the divided Particles thro’ a 
Microlcope, I was aftonillied at the prodigious num- 
ber of exceeding Imall Particles that occurr’d to my 
Sight, and which were of the lame Figure as before- 
laid. 
Moreover, I took Ibme of the thickeft Pieces of the 
horny Skin, but not half fo thick as the Back of a 
Imall Knife, and flit them into as thin Slices as I 
could, and placed them upon a clean Glals, with the 
Deflgn of dilcovering the exceeding thin Particles 
lying upon one another ; and having moiften’d them, 
they Ipread themlelves out further, and when they 
became dry again, they leparated into feveral Parts ; 
and I oblerv’d likewife that each of thele feparated 
Parts were compofed of many thinner Particles lying 
on each other. In order to have a clearer Notion 
of the Contexture of thole Particles, by which the 
Skin of the Hands and Feet of thole who are inured to 
hard Labour, or walk much, increales in Thicknel^ 
and is lurrounded, I cauled a Imall Portion of the 
aforelaid leparated Particles to be drawn, as appears by

complear, as they are reprefented in the laid Figure ; 
and according to the bell of my Obfervation, they
