luppofing that there arc channels made for its paffagc. 
Let us only reckon how xnany Vacuities a Scale has ,: 
whereb)^ it is nourifht fo as to grow, and that in the 
fpace of i part of a icale there may be io6 fuch Va- 
cuities, thro which the humours of the body may pafs, 
and that 200 fuch parts of: a fcale may be covered 
with a fand. jt will follow then, that the body may 
exhale out of 20000 places in a quantity no bigger 
then what a fand will cover. 
Hereout might be concluded that our Body is nothing 
but a Pore, notwithflanding what our Pbyficians fpeak 
of the Pores or paffages for fweat, as if there were fu^h 
places contrived by Nature for nothing elfe. For a 
drop of fweat though by the prefTure of the Air it be- 
comes round, yet it may be compounded of Particles 
coming from many thoufand places. 
I took fome fcales coming from the inward and 
mofl: callous part of the hand, and found them of the 
fame circumference with them of my Body , but as 
the one fort were very clear and tranfparent , fo the 
other were fo full of lines and fo thick I^efet with 
Globules, that they feemed to be compofed of no- 
thing elfe ; now we find by experience that the hand 
not only between the fingers^ but in the hollow of it, is: 
fubjedl to be moift, more than other parts of the body,- 
fo that tho the fcales fall off from the other parts of the 
body for want of nourifliment, yet the fcales upon the 
hands and feet are flill kept on by a clammy moifture and 
fat, which being brought to that place to be evacuated, 
flicks to the Scales, and keeps them together, leaving 
only fome fmall out-lets for the thinneftof the matter. 
By this means the skin of the hand, tho it be nothing but 
fcales, comes to be of an extraordinary thicknefs, which 
may be increafl by h^rd labour, whereby the moift- 
ure is brought into thofe parts, and the fcales are more 
packed and clotted together.
