hence 96,5 parts of this ftrong acid are equivalent to 100 of 
ftandard. 
Hence it alfo follows that 100 parts pure volatile alkali take 
up 316 of this ftrong nitrous acid, equivalent to 327,4 of ftan- 
dard, and fhould afford 416 of cryftallized nitrous ammoniac. 
adly, 100 parts nitrous ammoniac contain 24 of alkali and 76 
of the ftrongeft nitrous acid, equivalent to 78,75 of ftandard. 
Yet I muft obferve, that as the nitrous ammoniac employed 
in the teft folution was not purified by a fecond cryftallization, 
and contained fome excefs of acid, there probably is a flight 
inaccuracy in this experiment; but I form no doubt but this falt 
contains above 70 per cent. of the ftrongeft acid, and at moft 28 
of alkali. 
Accorpinc to Mr. Bergman, 100 parts pure volatile alkali 
take up 132 of the ftrongeft nitrous acid *; but this contradiéts 
the rule he himfelf lays down, that bafes that have a weaker 
attraction for a given acid, take up more of that acid than an 
equal quantity of a bafis that has a ftronger attraction to it 
can take up. Now by his own experiments, I00 parts pure 
mineral alkali take up 135,5 of the ftrongeft nitrous acid, there- 
fore 100 parts pure volatile alkali fhould take up much more.
