a watcrifh Moiflure, which to the naked Eye Teem’d 
yellowilli, and which was mingled witli an exceedin^^ 
number of fmall Particles, which made the Liquor 
thick and troubled, and ’twas alfo mingled with a yel- 
lowifli Oyl, which, where it lay thickeli, was of a Red- 
difli Colour. 
I took, moreover, fome other Pieces of Corral, and 
laid them upon glowing Wood-coals, and put them into 
fo great a heat, that the Colour turn’d from Red to a 
•fine Whitenefs^ and in that condition I threw it into 
fome clear Rain Water, and obferved, that the Parts 
thereof were immediately feparated, and the moil: parc 
of it in appearance turn’d into a White and Chalky Sub- 
Rance ; and the reafon why all the reft of the Corral 
was not diffolved, was, in ’my Opinion, becaufe afuEi- 
cient heat cou’d not reach the Parts of it ; for when 1 
took the Remainder, and heated it as I had done before, 
the fame Efi'ed: was produced in that likewife. 
The Water in which the Corral was quenched, had 
•not Rood a Minute, but that I cou’d perceive a Scum 
or Membrance of Salt Particles, with which it had^ been 
impregnated, upon the Surface of it, and which conllfted 
of fuclian unfpeakable Number of fmall Salts joyn’d to 
one another, that it was impoflible to difeover the Ei- 
■gure of them. 
After the Water had Rood fome Hours, I difeover’d 
abundance of Salt Particles, and of fo many feveral Fi- 
gures, that it was impoffible to deferibe them ; fome, of 
them were as clear as ChryRal, and it was a very plaa- 
fing Speftacle to fee fo many feveral Figures of Rich dif- 
ferent Shapes and Sizes, lying together in Rich a narrow 
compafs ; and as fine and fhining as they were when fur- 
rounded with Water, no lefs Dark were they almoR all 
of them when the Water was evaporated, and then it 
' appear’d* as if they were diffolved into a great many 
fmall Particles, Teeming to be of a Whitilh SubRance ;
