falt contained in it was =128,881 grs. The quantity of pure 
alkali was 35,35 grs.; the quantity of ftandard 80,52 grs.; the 
fum of both=115,87; then the remainder of the 128,881 grs. of 
falt muft have been water, amounting to 13,011 grs. 
Hence 100 parts of pure volatile alkali take up 227,7 of the 
vitriolic ftandard, and, including water, fhould afford 364,6 of 
cryftallized vitriolic ammoniac. Secondly, 100 parts cryftallized 
vitriolic ammoniac contain 27,42 of mere alkali, 62,47 of ftandard 
acid, and 10,11 of water. . 
Mr. Wenzcl’s method of inveftigating the proportion of in- 
gredients in ammoniacal falt is very ingenious, but. obfcurely 
related, and does not feem to have fecured even his own con- 
fidence. 
Into half an ounce of bis fpirit of vitriol * he gradually 
dropped 160 grs. of dry concrete volatile alkali, and found the 
weight loft amount to 86 grs. and hence he concluded this 
quantity of alkali to contain 86 ers. of fixed air. This con-
