The residue left on evaporation of 7000 grains of liquid 

 manure, burnt with soda-lime, was found to contain -898 grains 

 of nitroge,n. 



Another 7000 grains of the same liquid, evaporated with 

 hydrochloric acid, gave a residue which, burnt with soda-lime, 

 yielded 1-838 of nitrogen. 



The solid matter left on evaporation consequently contained : — 



Organic matters 39-79 



Containing I "49 of nitrogen. 



Mineral matters 60-21 



Consisting of — 



Soluble silica 1-66 



Oxide of iron -11

The specific gravity of the liquid at 62^ Fahr. was 1-007. 

 According to these determinations a gallon of liquid manure from 

 Badminton contained : — 



Ammonia (chiefly as ulmatc and humate of ammonia) 11-41 



* Organic matters 239-22 



* Containing 8-98 of nitrogen. 

 Which is equal to 10*90 of ammonia. 



Inorganic matters (ash) 361-90 



Consisting of —
