Figure, which fubfidiog (hoots into Angles, efpecially if 
they meet with any Moifture. 
Powdering fome Ctnnalar^ I expofed it to the Fire 
as before, and found therein fix-fided Figures, with fome 
triangular ones, whereof fome had one , others more 
Angles broken off ; with other differing Figures with 
one acute Angle, but there were no Squares or Oblongs. 
I often found amongft them a confiderable quantity of 
Oil, with fome traniparent parts winch I took for Salts ; 
this Oil lay fartheft trom the Fire: and I judged the 
Flame which I (bmetimes obferved, might be trom the 
burning of thefe Oily parts. 
I then poured Rain-water on fome of this Cinnalar 
that had been raifed by the Fire without flaming • and 
when it had flood in the Air till part was evapora- 
ted, I found a great number of Salt Particles of a lon- 
gifh Figure, as arereprefented N° 2. / And tho'fome 
of theie were bigger, )etl judged them to be formed 
of the fmaller ones united together. Amongft the reft 
fome were pyramidal, conftituted on a fix-fided Bafis, 
and ending in a point like little Diamonds. There were 
Salts of iome other Figures, as Oblongs, \Sc So that 
no eftimate can be made of thefe Salts. It is true 
Rain-Water affords a Salt, but it is in fo fmall a quantity 
as not to be confidered in this Experiment. 
Then I poured Rain-water on beaten Cinnahar, and 
alter fome Weeks fetling, and in part evaporated, I 
found therein an inconceivable number of Salt Particles, 
of which I could not difcern the Figures they were fo 
fmall, my beft Microfcope (hewing them no bigger 
than a Sand appears to the Naked Eye; only I fancied 
fome were Sexangular. Boiling fome of this Water r 
and evaporating part of it, the aforementioned Salts 
were to be fecn in greater quantity; fome of the lar- 
@U are reprefented, magnified, N! 2, K.L.L.
