Being not fully fatisfied with thefe Obfervations, I 
proceeded to fear eh. for theft Veflels in the Scales them- 
;i ;es, and to reprefent the Make of the Series, I have 
drawn a very fmall part -of one which in the Microfcop?, 
fee wed like clear Cryftal, with fcveral ftrcaks one under 
another, es Fig. 14, IKLM. \M is that part that is 
joyned to the Skin of the Fifh, and is about as long as 
two ordinary Sandi. I told five Ridges from / to K\ 
the Bream from whence I took this Scale, I ju ged about .

Spirit of Sal ArmoniaC) after a while expofing in my 
Clofet, began to fhoot, and examining the Eigufes, I 
found a great many fmall Particles coagulated into one 
little Mais, each of which were a little longer than broad, 
with a little cavity, fb that it feemed as if they had been
