fore reat 85,142 grs.; the quantity of pure alkali was 
50,05 —14=36,05 grs.; the quantity of ftandard acid was 66,7, 
the fum of both =102,75. But of this quantity only 85,142 
entered into the combination of the falt, therefore the remaining 
17,608 were mere water loft by the ftandard acid. And if 66,7 
parts ftandard lofe 17,6 parts water, in combining with mineral 
alkali, 100 fhould lofe 26,38. And confequently 73,62 parts of 
this ftrong acid are equivalent to 100 of the nitrous ftandard, or 
100 of this ftrong acid to 135,8 of the nitrous ftandard. 
HENcE 36 parts alkali took up 49 of the ftrongeft acid, con- 
fequently too parts pure alkali fhould take up’ 136, equivalent 
to 171 ftandard, and afford 271 parts cryftallized cubic nitre. 
SECONDLY. 100 parts cubic nitre contain 42,35 of alkali, 
and 57,65 of the ftrongeft nitrous acid, equivalent to 78,33 of 
_ ftandard nearly. 
Mr. Bergman’s determination varies confiderably from the 
refults of fucceeding experimenters. By his ftatement 100 parts 
cubic nitre contains 32 of alkali, 43 of acid, and 25 of water *. 
Hence 100 parts pure mineral alkali fhould take up 134,4 of 
the ftrongeft nitrous acid, or 135,5, as he elfewhere ftates it 
(which does not differ much from my account) and afford 312 
of cubic nitre.
