■the falts of the water being taken up by the fpungy 
filtrating paper. 
After this, the water was again fet on the fand heat 
and evaporated till a pellicle appeared on the fur- 
face ; and during the evaporation it threw up a great 
number of air bubbles : after this, it was fet in a cool 
place for three days, at the end of which time there 
appeared a quantity of thin lamella?, mixed with a 
fmall granulated fait, covered with a light coloured yel- 
lowifh liquor; thefe I feparated, and threw the liquor 
into filtrating paper ; and by thefe operations I got 
53 1 grains of a Salt which tallied fharp and fait, befides 
what had been taken up by the coffin, which had 
increafed gr. 9. in weight more than I had got of 
fait. This fait being put in a tea cup appeared next 
day white, and had contra&ed a little moilliure, but 
did not run per deliquium. 
The remaining water which was now a yellowifh 
ley, was again evaporated to a pellicle, and I feparated a 
quantity of white fait in lamella?, which remained 
moift, till it was fet in a tea cup on the land heat 
and evaporated to drynefs, when it weighed one 
drachm and 14 grains; this fait attracted more 
moilliure than the former, and feemed at firft as if 
it would run foon per deliquium ; but the next day 
it remained in the fame ftate. 
As I imagined that both this and the fait before 
feparated was moftly fea fait mixed with a bittern 
and oily matter, which prevented the cryftallifation ; 
I diflolved the whole of both in diftilled water, and 
evaporated with a very flow fire till a cryftallifation 
began to appear, and then fet it in a cool place, and got 
ibme large perfect cryftals of fea fait, and by repeat-
