*'Afair idea of the general composition both of the 

 solid excrement and of the urine is given by the follow- 

 ing table:

*'The extreme richness of the urine, both in ash con- 

 stituents and nitrogen, is very evident. In the case of 

 highly-fed oxen (and cows) the dry matter of the urine 

 is seen to contain over twenty per cent of nitrogen. 

 Urine readily undergoes fermentation, the urea being 

 transformed into carbonate of ammonium. As this is a 

 volatile substance, a loss of a part of the nitrogen voided 

 may easily occur, especially if an insufficient amount of 

 litter is employed. 



** The relative value of the manure produced by differ- 

 ent foods is determined by the relative richness of the 

 foods in nitrogen and ash constituents, but chiefly by the 

 amount of nitrogen, this being the most costly ingredient 

 of purchased manure. The average amount of nitrogen 

 and of the two most imjDortant ash constituents con- 

 tained in the ordinary foods is shown in the following 

 table:
