PERCENTAGE COMPOSITION OF SOLID AND LIQUID EXCREMENT. 

 SHEEP FED ON HAY. 



OXEN WITH NITROGENOUS DIET. 



Both the solid and liquid excrements of the sheep are 

 far drier, and therefore more concentrated, than those 

 of the ox, whose food includes a much larger quantity of 

 water. 



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

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

 the more highly-fed oxen, the dry matter of the urine is 

 seen to contain over 20 per cent, of nitrogen.
