 The cows received a nitrogenous diet of hay, cake and 

 corn ; no roots were given. The average yield of milk 

 was 22*8 lbs. per day. 



The immense loss of nitrogen and potash which 

 must occur when the urine is not preserved is strikingly

Some idea of the general composition of the solid 

 excrement, and of the urine of various animals, receiving
