Dcpreffipns than Protuberances. This is an Argument that -there 
has been fome kind of Liquor contain’d in thefe 'TaptlU or Vef- 
fels, as I may call them, which at the drying of the Skin is eva- 
porated ; and therefore I fuppofe this brawny part of the Cutis 
to he a Congeries of dacfou excretorij , running in a Parallel Line 
from thefe Glands to the Veficles, and conveying the Liquor 
to be contain’d in them, till it be evaporated by Perforation y 
and thefe Veflels feem to have been both fo big and numerous in 
this Animal, that they makeup at leaft two parts of the inner 
Surface of the Cuticula y the Blood Veflels and the Depreffions 
together fcarce make up a third part. They feem alfo to be 
lodg’d in. the Cutis by the one half, and-in the Cuticula by the 
other y for in fome Place? of the Cutis I obferved the Depreffi- 
ons as numerous, and feemingly Parallel to thole in the Cuticula y 
and that, notwithftanding the MembranuU, where the Humour 
was included, which now being dry’d and collaps’d, may take 
up fome Space in the Depreffion of the Cutis. By this Account 
both of the Cuticula and Cutis, 1 come to enquire Firfb, how the 
one fhould fo firmly adhere to the other, when there feems to 
be no Communication by Fibres betwixt them, as appears by 
their eafy Separation both by Fire and Water: Secondly, how 
confiderable thePerfpiration may be.- As to the Firft 5 fince the 
Cutis and Cuticula are two Giftinft Membranes, their Cohefion- 
feems to be mutual : Firft, thefe Pyramids, which receive the 
Hairs, are impacted in the Cutis , and clofely furround their Roots y 
and then thefe Papilla are impafted in the Cuticula , which fo long 
as they are diftended with the humour fit for Perfpiration, will 
not readily quit the Depreffions in the Cuticula > unlefs the Hu- 
mour be fuddenly evaporated by Fire, or the Sides of thefe De- 
preffions or CelluU be relax’d by Watery and there may be a 
certain Vifcofity which obduces the Surface of both, as it were 
fo much Glue, which either the Fire may dry up too much, or 
the Water dilate; fo that the one can be foon feparated from the 
other, and the Hairs either be ptffi’d from their place, or quit 
their common Involucrum. As to the fecond, viz,. The Perfpira- 
tion, 1 fhall offer no other Calculation than what is already made 
by Dr. Moulins : He fays, ‘ the Pores mull; be both numerous and 
1 large for Perfpiration, efpecially if we confider SanBorius his 
‘ Statical Observations of a Male’s infenfibly perfpiring inaWin- 
4 ters Day $50. and upwards ; which is fomething more than 5 -\ of 
‘ 2n ordinary Man's weight, fuppofing him to be 17083. and
