ticularly then any one may obferve everyday ; fuppo 
fing only that he thinks that our Fleih thus covtred 
at any time, with a Blifter, is made up of many and 
di\^ers Vtflels, cut of which the Difcharged Water may 
come : And not to be Nice with our Author, f mufl: 
obferve that he falls into as great errors, as can be ima« 
gined , when he pretends to fee more than the moft 
common and ordinary Perfon. He fays that the parts 
of Fire, and confequently thofe of a Bliftering Tnftru- 
ment, make their way without a folutio continui ; that 
they attack the ends of all the Veflels, or the extremi- 
ties of ali the Veflels ; and to be more particular he 
tells us, that they, firft of all, affeft the Spirits. Now 
I fay he tells us all this, becaufe he does not endeavour 
to prove any one but the laft and that, I think, he 
had better left unproved too. It looks a little oddly 
that all this fliould be done , merely by entering the 
Pores, and yet it is not that he feems to hint ; tho' f can- 
not well imagine how he did apprehend it to be done : 
But that they fliould attack the extremities of the Vef» 
(els, and even the Spirits firft, is a vaft Contradidion 
to the Circular Motion of the Blood, and to the way 
of making a Blifter : We fliall find unanfwerable Diffi- 
culties , not only in the Circulation of the Blood, but 
that the Blood fliould move at all ; if once we are able 
to prove that Veflels have ends, or that ihcy terminate 
in any manner of way but in themfelves. 
It cannot fo much as be brought as an excufe for this 
Author , that by the extremities of the Veflels he 
may intend the Veflels of the extremities: this is by 
no means proper in this place , if his words could bear 
it. The reafb.i, indeed , he brings for the parts of a 
Blifter firft beginning with the Spirits, is the moft won- 
derful thing in the whole matter, even more than Bli- 
ftering it felf,- becaufe, fays he, they are of no cfTed:
