quently contained (at the rate of 33,59 per cent.) 134,36 real acid,. 

 The 136 grains Carrara marble contained (at the rate of 55 per 

 cent.) 74,8 of lime. 



Consequently 100 parts lime take np 179,5 of real nitrous 

 acid, and 100 parts real nitrous acid take up 55,7 of lime. 



Lavosier diffolved 972 grains of flacked lime, dried in a heat 

 of about 600^, in 3456 grains of nitrous acid, whofe fp. grav. was 

 1,2989, and confequently contained (at the rate of 36,7 per cent.) 

 126S grains real acid ; from the 972 grains lim.e we muft dedud 

 (at the rate of 28,7 per cent, water abforbed. in the flacking) 

 268,9 of water, and alfo 35 grains of fixed air, abforbed while 

 flacking and drying, there remain then 668 of mere lime, and thefe 

 took up 1268 of real acid, then 100 grains of lime would take up 

 190 of real acid, i Lavofier, 198. Perhaps the difference arifes 

 from my computing the quantity of real acid from a fpecific gra- 

 vity taken at 60'', whereas his might have been taken at a higher 

 degree. 



Bergman found 100 grains of nitrated lime, ivell dritd (that is 

 dried in air) to contain 32 of lime ; by the above analogy the pro- 

 portion of the other two ingredients may be found, for fincc 100 

 parts lime take 179,5 ^^ ^^^^ acxA, 32 fhould take 57,44, confe- 

 qucntly the remainder, viz. 10,56 are water; if the nitrated lime 

 could be perfedly dried, it would contain about 36 per cent, of 

 lime and 64 of real acid.
