Or according to another estimate, a cow consuming 26.41 ibs. 

 of grass daily, emits in shape of dung 11.13 Ibs.; and con 

 sumes, in the support of its body, 15.28 Ibs. 100 parts of 

 fresh fallen cow-dung will afford 0.614 or five-eighths of a 

 pound of pure ammonia, or about 2 Ibs. 2 oz. of carbonate of 

 ammonia (sal volatile) of the shops. (S. L. Dana.)
