14 On Liquid Manure. 



The following is the composition of the solid substances in this 

 sample of liquid manure : 



Organic matters 38-94 



Containing 2 504 of nitrogen. 

 Which is equal to 3-040 of ammonia. 

 * Inorganic matters (ash) 61'06 



100-00 

 * Consisting of 



Silica -95 



Lime 10*75 



Magnesia 1 37 



Chloride of sodium 14-25 



Chloride of potassium 6 36 



Potash 11*08 



Phosphoric acid .. .. .. 1*91 



Sulphuric acid 2*81 



Carbonic acid and loss 1 1 58 



According to these analytical data the liquid manure drawn 

 in 1857 from the tank on the College farm, Cirencester, had the 

 following composition : 



An imperial gallon contained: 



Water and volatile ammoniacal compounds .. 69878*900 

 Solid residue (dried at 212) matter 121-100 



70000-000 

 A gallon contained : 



Ammonia (volatilized on heating, and present chiefly \ oo.q4 



as carbonate and humate of ammonia / 



Organic matters 47*157 



Containing 3-033 of nitrogen. 

 Equal to 3*683 of ammonia. 



Mineral matters (ash) 73-943 



Consisting of 



Silica 1-154 



Lime 13-011 



Magnesia 1-660 



Potash 13-411 



Chloride of potassium 7*712 



Chloride of sodium 17-258 



Phoshoric acid 2-304 



Sulphuric acid " 3-408 



Carbonic acid and loss . 14-025 



144-064 



There is a very marked difference in the composition of this 

 liquid and that from Badminton or Westonbirt. In the first 

 place, it will be noticed that the proportion of solid matter in the 

 Cirencester liquid is very much smaller than in the other two.
