the muriatic acid combining with the vegetable 

 alkali, forms fal digeftivum fylvii, which remains 

 diffolved. 



b. By the addition of the mercurial folution 

 (c) yellowim clouds will immediately be formed, 

 and in time a precipitate of the fame colour will 

 be depofited. The mercury, leaving the nitrous 

 acid, unites with the vitriolic, forming turpith 

 mineral, which is infoluble in water, though a 

 part of the vitriolic acid and mercury remain 

 diffolved along with nitre, formed by the nitrous 

 acid uniting with the vegetable alkali. 



c. The addition of the folution of fugar of 

 lead in water feparates a white precipitate, as 

 mentioned page 49. c. The vitriolic acid unites 

 with the lead, while the acetous acid combines 

 with the vegetable alkali, forming diuretic fait, 

 which continues diffolved. 



d. By adding an equal quantity of highly 

 rectified fpirits of wine, the mixture will become 

 turbid, and by degrees fmall chryftals of vitriol- 

 ated tartar will be formed at the bottom, for rea^ 

 fons afligned page 50. d. 



( c) Mercury combined with nitrous acid by the affiftance of 

 heat.
