kn ounce of crude tartar cannot be dif^ 

 iblved in lefs than ten ounces of water j 

 khd that quantity of cold water will 

 make no folution until it is brought to 

 boil, and continues to boil for fome time, 

 hew water being added to fupply the 

 wafle. Even that compound fait, made 

 6f the fixt fait and chryftals of tartar, 

 which, from its folubility, with refpecfl 

 to common tartar, gets the name of tar- 

 iarus folubilis, requires little lels than ten 

 times its weight of warm' water to diffolve 

 it fully, 



VII. Some bodies can be diflblved in 

 liquors of very different qualities, but in 

 different proportions, with different helps, 

 appearances, and effedls. 



Common fulphur or its flowers dif^ 

 folve in any oil, but more eafily, and in 

 greater quantity, in a thick, mild, ex- 

 prelTed oil, than in a thin, hot, aromatic, 

 diftilled oil. When flowers of fulphur 

 are digeiled with oil of olives, or lint- 

 feed, it becomes a thick balfam : Three 

 ounv-res of oil will diffolve one ounce of 



fulphur ^
