I Taw likewife feveral Long and Slender Salts, that ap. 
pear*d like Fig. i2, Z2 3 the which Salts were fo clofely 
linkt and joyn'd to each other, that one would be apt to 
take em for one long and flender Particle, but viewing 
them more narrowly they appeared to be feveral linkt to- 
gether. 
Moreover, I try'd thcfe Afties three feveral rimes in a 
ftrong Fire, ( having kept them in a fma 11 clean Wooden 
Box) to fee what Volatile Salts could be e>jtrafted from 
them 3 and always obferved that firft a very clear Liquor 
did exhah from the A(hes, which at the laft Evaporation 
was accompany 'd with a Yellowifli Oyl, and which Oyl 
was coagulated after (uch a manner, as if they were min< 
gted with Salts. 
I faw alfo a great many fmall Wal*ery parts, which one 
might call a Spirit ^ and an extraordinary great number 
of little Bubbles, which I judged to be really Oyl, of 
which fome of them were fo much fmaller than others, 
that they. almoft efcaped the fight through a good Mi- 
crofcope. 
There were moreover on the fide$ of the Glafs fome 
very fmall Particles, that were neither Water nor Oyl, 
which' limagin'd to be Volatile Salts, but not being able 
to difcover in <m any exafl: form^ I can fay nothing cer- 
tain of them 3 and I have alfo always obferved that when 
I brought the Glafs where it was cover'd with the Tobac- 
co Afties, to fuch a ftrong Fire, that it was put into 
Fufion, the Afhes, or rather the Salts thereof, united 
themfelves with the Glafs, and the Glafs afcended with 
Air bubbles, and with a ftrongerPire there j was eauCed a 
Hole in the Glafs. 
I have feveral times, for my Curiofity only, taken a 
fmall piece of our Delft Earthen Ware, which was but 
once baked, and confequendy not Glaz'd^ and made a 
fmall Cavity in it, fo that it ferved me for a Teft or Shelly 
fttch as the Refiners with Bone Afties ufe, and put into the
