had all been feparate Pieces, and none of them united 
to one another. 
Again I placed feveral little Pieces of this hard Skin, 
which I had cut off at' the thickeft Part of it, before a 
Microfeope, and moiften’d them with fair Rain-Water 
when I put them upon the Glals-Piate, by which 
Means they acquired a great Extent ; and being dry’d, 
they flirunk again, and thereby appear’d in feveral 
long Particles, and each of them feem’d to confifl: 
of other long Particles, as they are rep: dented 
in Fig. 7. E F G H. So that EH or F G, was the 
Thicknds of that Piece of thick Skin, which I had cut 
through. 
From this Oblervation, I confider’d with myfelf, whe- 
ther one of thefe long ftripe-like Particles, liich as ap- 
pear’d to the Eye at E F or H G, might not be the 
Thicknefs which the horny Skin had acquir’d in the 
Space of a Month ; and whether the very thin Particles, 
which appear’d in fuch a littleStripe, were not the Accre- 
tion which the hard Skin receiv’d in one Day. Thislaft 
mention’d little Piece, reprefented by Fig. 7. was not 
io large to the naked Eye as a common Grain of Sand. 
And whereas I placed before a Microlcope another 
very Imall Piece of Skin, that was fomething thinner 
than the former, I could perceive the exceeding thin 
Particles reprefented by Fig. 8. IKLM, which were 
the Strata., or Beds, in which the horny Particles 
of the Skin lay, and fo compofed the Thicknefs 
thereof 
For my further Satisfadion, I fent for a Mafbn’s 
Servant, who was a laborious Workman, and cut out 
of his Hand, where it was moft thick and brawny, 
two Bits of the hard Skin ; and then I flit it into finall 
Slices, and obferved eafily enough the thin Particles 
lying upon each other, bur could not fep'arate the little 
Scales
