volatile alkali, a very small quantity of calx of iron was preci-

EXPERIMENT III. 
The residuum of the second experiment, which was not 
soluble in alcohol, was digested with distilled water, and often 
stirred. The water took up 1204 grains. This solution was 
filtered, the residuum often edulcorated and dried ; this weighed 
188 grains. The solution was evaporated in a gentle warmth 
to one third, and being then set in a cold place, 12 grains of 
selenite were separated. Having further evaporated the re- 
maining solution, I now mixed it with double its weight of 
alcohol, and after having again heated this mixture, I let it 
cool gradually ; thus all the vitriolic salts were separated. I 
again dissolved this saline mass in distilled water, and, after 
gentle evaporation, obtained crystals, weighing altogether 
1200 grains, and consisting of vitriolated tartar, and vitriolated 
soda: from the remaining ley I obtained, on further evapora- 
tion, 10 grains more of common salt. There were no traces 
of an uncombined alkali, which must otherwise have now 7 
shewn itself. The 1200 grains of mixed salts, which had crys- 
tallized first, were again dissolved in water, and this solution 
made to boil ; a hot solution of mineral alkali was now mixed
