grown much diicker^ as well as br6ader and longer, ha- 
ving been coagulated with (o many (mailer Salts, thai 
they appeared to be folid Cubical Bodies of Cryftal 5 but I 
could not difcover, in a great number of thofe Salts, any 
two Salt Particles that were hke one anoihcr. 
Now when I perceiv'd that the wild Cryftal, after I had 
heated it glowing hot^ had diflbiv^d it felf into fuch in- 
conceivable numbers of fmall Particles in the Water, 1 took 
a fmall Copper Porringer, the cavity of which made half 
a Globe 3 and having cleao'd the fame very weil^ I put in- 
to a little Water a little of the faid Cryftal, and placd it 
over a Wood Coal, with (o much heat, that it was boil- 
ing in the fpace of a minute, and kept it there till the Wa- 
ter had almoft evaporated 3 after which, I mixt the re- 
mainder with Rain Water, and put foay of the fame 
upon feveral clean Glaffes, to fee, whether the Water, by 
the above-mentioned boiling, was not alfo impregnated 
with Salt Particles. 
This Water being moftly exhaled, I difcovered in it 
feveral Salt Particles, almoft of the fame figure as the for- 
mer 3 but, forafmuch as the Water in which the glowing 
wild Cryftal was put; had been v/Iiolly exhaled ^ the kft 
Glaffes were altogether covered with a Vapour which 
moftly furrounded the Salt Particles^ the which Salt Parti- 
cles I imagined to be very fofc, and which were alfo cover'd 
with a very thin Membrane. 
Tq fatisfy my felf further concerning the laft Obferva- 
tion, I beared the Glafs upon which the laft Salt Particles 
Jay, till the Vapour or Moifture was quite exhaled, "^nd 
then I could perceive a great many fmall Salts that I had 
not feen before, but nothing near fo many as came out of 
the firft Water ^ after the fpace of about an hour, it being 
moift weather, I viewed the Glafs again, and found tiie 
Waterifh Vapour lying fo thick about thp Salt Particles, as 
if none of it had been exhafd,
