cording to all appearance, was nothing elfe bat the coa> 
gulated Salts. 
After that the burnt Fragments of Pearl had been in- 
fufed in this Water two or three Days, I difcovered a 
few large Salt Particles, like the firft mentioned Sales, and 
of divers Figures, feme of them were as clear as Chryftal 5 
and I could likewife perceive in fome of the ftmil Salts, 
that lay at diftance from the reft, their particular Figures, 
and they aifo were as clear as Chryftal, "but where they 
lay thicker together, they appeared to the naked Eye to 
be nothing but a white Matter. 
After thefe burnt Pearls had laid about five Days in the 
Water, their Salts had fuch an influence upon Copper, as 
to turn it Green-in feveral Places. 
In order to be further fatisfied, I took fome of the a- 
bovememioned Pearls , and folded them in a thick Poft 
Paper 4 times double, and beat ’em upon an Anvil to Pow- 
der y then I put the Powder into a little clean Copper 
Porringer of a Hemifpherical Figure, ahd poured clean 
Rain Water upon the fame, then fet it over the Fire 
and boiled it till two thirds of the Water were evapo- 
rated. 
I took fome of the Water, and put it upon clean Glafs 
Plates, in order to fee how far the Pearl Powder had im- 
pregnated the fame with its Salt Particles. 
After that this Water had flood fome Hours, it feem’d 
to me as if there was fomething floating upon it, but 
when I view’d it with a Microfcope, I could not Judge 
it to be any of the Salt Particles, but rather fmall whole 
Pearls. 
The Water that I had placed upon clean Glafles ha- 
ving been exhaled, I view’d the remaining Particles with 
my Microfcope, and faw feveral exceeding fmall Salts, 
of the fame Figure with the former.
