but that it tranfmits the Colour of the Blood ; which 
is, at fuch times, more forcibly driven into the capil- 
lary fubcutaneous Veffels, and fliines thro’ the Epi- 
dermis \ bur, before, thefe Veffels contained only a 
ferous Liquor, and, accordingly, the Skin appeared 
of that Colour : Which will further appear upon 
fqueezing fuch red Parts, which drives the Blood out 
of them, and makes them appear white ; whereas, 
on removing fuch Prelfure, they recover their Co- 
lour, as the Blood does its Place. 3. The yellow 
Colour of the Skin in the Jaundice is a further Proof 
of this Afl’ertion where the yellow Bile is diffufed 
thro’ the Velfels of the Cutis , and appears thro’ the 
Epidermis ; but no one will imagine, that the Epi- 
dermis itfelf receives this vifcid Bile into its Velfels; 
which are fo fmall, that many accurate Anatomifts, 
as Morgagni , have denied it to have any Veffels at 
all ; and the moft accurate could never fhew them. 
4. The pale Look of thofe, in whom the Blood is 
vifcid, or circulates with little Force, fhews, that the 
Epidermis then tranfmits the Colour of the Juices 
and Fibres below it, which are then unmix’d with 
red Blood. 5. The fame is manifeft in thofe whofe 
Blood is poor and ferous, as the Leucophlegmatic, 
&c. in whom the Epidermis tranfmits the Colour of 
theWateror Scrum under it. 
From hence it appears, that the Epidermis is a 
tranfparent Membrane, which eafily (hews the Colour 
of the Parts under it, in the fame manner as the 
Cornea of the Eye tranfmits the Colour of the Iris. 
But this will appear more plainly, from fome Con- 
fderations below j where we fhall afllgn the Caufe 
of this Peliucidity ; and fhew, that the Numbers of
