Mflceilaneous Qbjervations on Salts, See, 2 if 
That the Shoots of Crydals are formed in 
a Fluid drongly charged with crydalins 
Matter, will readily I believe be granted, and 
likewife that their Formation is nearly in 
the fame Manner as the Formation of the 
Cry dais of diffolved Salts. But perhaps it 
may be inquired in what Time this Opera* 
tion is brought about; and though that 
much depends* on the Strength of the Solu¬ 
tion, and the Evaporation of the watery Part 
of the Fluid, there mult certainly be a Crifis 
when the Crydals begin to form ; after 
which, little Time perhaps is required to 
bring them to Perfection: for, when the 
floating Particles come within the Sphere of 
each other’s Attraction, they rujh together and 
quite, according to their refpeCtive Figures, 
and that in a fhort Time; as is plain in freeze 
ing, and in artificial Crydalization, which is 
brought about in the fame Way. 
Great Diiputes have arifen among Nqtu - 
ralifts concerning the Formation of Corals 
and Corallines under which Names Bodies, 
of very different Contextures., Subdancas 
and Figures, are I think too indifcriminately 
included ; their Appearance indicating not 
pnly a Difference in Species, but even in Ge¬ 
nus. Some inlid on their being in general 
* As I think it needlefs to enter into Particulars, by 
Corals and Corallines I intend, in general, whatsoever the 
Naturalifts include under the Names of Q or allium, MiUepora , 
, Tjgladripora, Cor a llina, &c.
