According jto Wenzel 122,66 grains of Hmc take up 240 of 

 his ftrongeft acid, confcquently 100 of lime would take up 195,64 

 offuchacid, but this quantity is equivalent to only 1^9 of my 

 real acid, this difference I cannot account for.

Nitrated Magnesia. 



By my experiment 100 parts mere magnefia require 210 of real 

 nitrous acid for their faturation. 



And I bo grains real nitrous acid take up 47,64 of mere magnefia. 

 100 grains cryftallized nitrated magnefia contain 46 real acid, 22^- 

 magnefia, and 3a of water, as I found. 



According to Wenzel 77 grains of the magnefia he employed 

 contained but 32,13 mere earth, and yet required 240 of his fp. of 

 nitre for their faturation, which fp. of nitre, by my calculation, 

 contained but 67,2 real acid, and confequently 100 grains mere 

 magnefia would require 209 real nitrous acid ; by his own calcula- 

 tion 240 of his fp. of nitre contained 82,5 of his ftrongeft nitrous 

 acid, and confequently 100 grains mere magnefia fhould take up 

 256 of fuch acid, = 207,87 of my real acid.
