ift, 760 grains of nitrated vol-alkali contain, by my account, 57 per 

 cent, nitrous acid, 23 percent, vol-alkali, and 20 per cent, water. 



Confequently of acid 433j2 



vol-alkali 174,8 

 water 1 5 2,00 



760 



Again, 54 grains nitre contain, by my account, 23,76 real acid, 

 and thefe, fubllraded from 433,2, leave 409,24 to form water and 

 the rudimental nitrous air. 



Hencb 760 — 23,76 = 736,24 grains form the quantity to be 

 accounted for; we mufl alfo affign the reafon why rudimental ni- 

 trous air, and not mere nitrous air, was left. 



2dly, Of the 281 grains of water, found by Berthollet, 152 

 pre-exifted by my theory, confequently the formation of 129, and 

 of the additional quantity loft, muft be accounted for. To efFedl 

 this we are to obferve, 



3dly, That according to Berthollet's analyfis 100 grains vol-alkali 

 confift of 19,34 of hydrogen, and 80,66 of mephite, confequently 

 that 178,4 grains of vol-alkali contain 33,8 of hydrogen. 



4thly, 100 grains water, by the moft exacfl experiment, re- 

 quire for their compolkion 14,338 grains of hydrogen, confe- 

 quently 129 grains of water require 18,4.97 of hydrogen, 9 Ann.
