This therefore would have been the quantity of pure 
vegetable alkali, faturated by 4 ounces of the marine 
acid contained inthe receiver C, had it not been 
mixed with vitriolic acid; but we have already feen 
that thefe 4 ounces contained 104 gers. of the vitrio- 
lic ftandard ; and fince 100 parts vitriolic ftandard 
take 108,7 of mere vegetable alkali, 104 grs. of this 
ftandard fhould take - - - - 113,04 
Confequently there remained to take up the marine 
acid only 794,35—113,04 - - - = 681,31 
And fince 100 grs. pure vegetable alkali require to 
faturate them 59,3 of the ftrongeft or real marine 
acid, 681 require _ = - - - 404. 
Therefore 4 ounces of the fpirit of falt in the receiver 
C contained 404 ers. of the ftrongeft marine acid ; but 
the receiver C contains in all 11 1b. 10 0z.=186 oz. 
of this fpirit of falt; and fince 4 ounces contained 
404, 186 oz. muft have contained - - 18786 
Again, the 4 ounces of condenfed vapors, that is to 
fay as much water as contained 4 ounces of thofe 
vapors, faturated 38 of the alkaline folution, which 
38 ounces muft, from what has been above faid, 
have contained of pure alkali - - - 2414 
And fince 100 grs. mere alkali take 59,3 of the 
ftrongeft marine acid, 2414 muft have taken - 1631
