I cannot well omit(in this place, relating toTranfpir&« 
tion) what fome time fince happened to me; which was 
an extraordinary -itching on the. upper part of my Mole, 
which viewing with an enlarging Looking-giafs, I found 
a whitifh fcurfy fpeck which I took off, but not without 
feme pain 5 itftuckfo firmly to the Skin ; observing it with 
my Microfcope, I found the reafon of its Scurftnefs, and 
of its flicking fo faft ; for this bit of the skin conftituted 
of Scales, was thick befet with little Conical Bodies, caiiP 
ed as I judged by a more than ordinary expulfion of a 
thick Matter or Pus in this place, which not being able 
to pafs through the Scales, much lefs through the Vef~ 
fels of the Scales, had made feyeral pits or dents in" the 
Skin 5 and forceably railed and torn off the Scales from the 
Skin, both which had caufed the Itching and made the 
white fcurfy fpeck , fome part of the true skin being fe- 
parage d : and the little pain that I felt was caufed by the 
faft flicking of the Conical Bodies to the Skin, which in 
feparating were torn there-from ; but what feemed ftrange 
to me, was that in a Days time, and (bmetimes fooner^ 
a new fcurfy Particle was formed like the former, be- 
fet with the fame pointed parts, and this 6 or 8 times one 
after another, as faft as I took them off. I have given the 
Figure of this little bit of Skin, having never obferved 
the like where I might well expert it, viz. in Leprous Per- 
hns, whofeDifeafe is a fcurfy (eparation of the Skin. 
Fig. 8. is the bit of Skin of the true fize by the naked 
Eye. Fig. 9. ABC D the fame magnified , in which 
the Conical Bodies formed out of the Matter or Pus are
