On Liquid Manure. 11 



The residue left on evaporation of 7000 grains of liquid 

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

 of nitrogen. 



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 1'49 of nitrogen. 



Mineral matters 60*21 



Consisting of 



Soluble silica 1*66 



Oxide of iron *11 



Lime 4*19 



Magnesia 2*55 



Potash 18*67 



Chloride of potassium 12*97 



Chloride of sodium .'. -.. 7*65 



Phosphoric acid 1*58 



Sulphuric acid .. .;./.;' 6*20 



Carbonic acid and loss 4*63 



100*00 



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 ulmate 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* 9u 



Consisting of 



Soluble silica 9*98 



Oxide of iron *68 



Lime 25*18 



Magnesia .. 15*33 



Potash 112*26 



Chloride of sodium 46*03 



Chloride of potassium 77*38 



Phosphoric acid 9*51 



Sulphuric acid 37*60 



Carbonic acid 27*95 



612*53 



On comparing the composition of the two samples from 

 Westonbirt and Badminton, it will be found that the latter con- 

 tains both more organic and mineral matters in solution. Not-
