the Butchers kill the Hogs, the pain that is caufed by the 
Wounds they then^ive them, might alfo force thofe 
(lender (harp- pointed Particles to come out of the places 
cf the retv. 
I difcoverd likewife a great many round protuberant 
Particles between the faid Particles, the Diameter of 
which was twice as big as of thofe in Fig» 12. between 
Kand and when the Skin came to dry, I cou’d difco- 
ver in a great many Places, the extern il or flicking out 
Membranes drawn inwards in fuch a manner, that one 
wou’d take ’em for Valves. 
From this appearance I began to confider, whether 
thofe fort of Particles were not made for the difcharging 
the Tongue of its fuperfluous Matter 5 and the rather, be- 
caufe I had oftentimes obferv’d, that thofe Veffels had 
nothing included in them, but a moifVnefs which moflly 
evaporated, and left as ’twere an empty place behind it, 
which extended it felf as far as the thicknefs of the Skin. 
After I had brought my Obfervations thus far, I de- 
termin’d to feparate the uppermoft Skin from the Parts 
that lay under, which I brought to pafsin fmall Parcels^ 
and when I had divided fuch an uppermoft Skin, I cut 
from it, (in chat part where it had been united) with a 
(harp Razor, feveral Scaley Particles, which having pla- 
ced before the Microfcopc, I obferved with wonder a 
great Number of Holes or Cavities, which when they 
were placed oppofite to the fight appear’d wider, but 
when removed from the fight narrower, fo that each Ca- 
vity feem’d to be of the Form of a Tap or Funnel 5 and 
forafmuch as each of the faid Cavities had, as it were, a 
Body fa ft about them, I concluded, that thefe were cer- 
tainly thofe Parts which in Fig, ii. are deferibed by H, 
H, or in Fig, 12. by I, K, L, M, and thn they were bro- 
ken of from their bottom or part that lay under them.
