in the economy of the animal have been rejected. The 

 animal has used some of the digested matter to build up 

 its tissue, to make bone, etc., while the remainder is found 

 in the urine. The quantity of urine voided will depend 

 on the quantity of water consumed, but again, the more 

 produced the poorer it will be. 



The following analyses will give some idea of the 

 composition of the urine of different animals (Stockhart).*

It will be seen from the foregoing, (a) that the urine 

 shows considerable variations, is rich in nitrogen, and 

 contains notable quantities of alkalies (potash), (/>) that 

 it is extremely poor in phosphoric acid, (c) that the urine 

 of the sheep is, weight for weigKt the most valuable and (d ) 

 that the urines of the sheep and horse are more valuable than 

 that of the bovine tribe. The animals in this case were 

 fed on more or less drv food. The percentage of water 

 in the urine of bullocks often amounts to 95 per cent, but 

 sometimes falls to 88. The nitrogen is also often less 

 than that indicated while sometimes it exceeds it. The
