the operation. I had no better fuccefs when the fulphur, pre- 
vious to its diftillation, had been moiftened with marine acid. 
Again, I expofed x8 grains of liver of fulphur to fix cubic ; 
inches of fixed air , thermometer 70% for four days. The 
liver of fulphur was fomewhat whitened on the furface ; the 
air had not an hepatic fmell, but rather that of bread. It was 
not converted into phlogifticated air, but feemed to have taken 
up fome fulphur, which lime-water feparated. It was not in 
the leaft diminifhed, and therefore feems to have received an 
addition of hepatic air, or rather of fulphur. 
I alfo expofed a quantity of fulphur eo -martial pajle to fixed 
air, for five days. The fixed air was not diminifhed, but re- 
ceived a flight acceffion of inflammable air. The pafte itfelf, 
taken out of this air, and expofed to the atmofphere, heated 
ftrongly. 
Laftly, I expofed 3 grains of fulphur to about 12 cubic 
inches of marine air. It was not diminifhed in four days ; nor 
was the fulphur fenfibly. On adding one - cubic inch of water 
*0 this air, it was abforbed all to one inch, and this had an 
hepatic fmell ; fo that neither was the fulphur decompofed, 
nor the marine acid converted into inflammable air. The wa- 
ter had alfo an hepatic fmell, and evidently contained fulphur; 
far it precipitated the folution of filver brown mixed with 
white, and the nitrous folution of copper reddijh brown , and 
when vegetable fixed alkali was dropped into it, let fall a white 
.precipitate, namely, the fulphur.
