Some of them however fhoot farther into 
the Drop, in the Manner fhewn at 3, 4, 
and 5 : and many fo fhot out have other 
fmaller ones protruded from their Sides, 
parallel to one another, and forming an 
Angle with their main Stem of about 60 De- 
grees, as at a> a : when the Procefs is nearly 
over, many extremely minute Spicules arife 
in the Interfpaces; fome uniting in, or ra¬ 
ther {hooting from Centers, and making 
a very pretty radiated Appearance, like 
what was before obferved in the Blue Vi¬ 
triol ; whilfl others of the fame Spicules are 
feen fcattered and difperfed about the Drop 
in all Directions, as at 8. Thefe Spicules 
may be termed a CharaCteriftic of the Vi¬ 
triols, being ufually found in all of them, 
when examined by the Microfcope with 
Care; but as fometimes the Green is feen 
without them, I have taken no Notice of 
them there. 
The Figure fhewn at 6 is feldom to be 
met with, but when the Fluid Part of the 
Drop is fuffered to evaporate without any 
Pleat ; and it feems nearly to approach the 
regular Cryflals, which are next to be de- 
feribed. 
As a Solution of our prefent SubjeCt does 
not fo eafily cryflalize by the common 
t It is obfervable, that many of the Pyrites exhibit 
Lines diverging from a Center, exa&ly in the fame Man¬ 
ner..
