These results are sufficient to show how very inferior the absorp- 

 tion of nitrogen is from diets of a type in which the main source 

 of protein is the pulses i.e., diets in which the other constituents 

 being poor in protein, an effort is made to bring the diet up to 

 the normal protein standard by increasing the quantity of pulses 

 to an excessive degree. The effect of large quantities of pulse is 

 not only to cause a decrease in the percentage of protein absorp- 

 tion from the pulses themselves, but also to lessen the degree of 

 protein absorption from the other constituents of the diet. In 

 Agra Gaol the amount of pulses entering into the composition 

 of the diets experimented with was too high, practically never 

 less than 7 ounces, and often over 8 ounces ; this would account 

 for partially at least the lower coefficients of absorbability 

 obtained for the foodstuffs investigated in that gaol. On the 

 other hand, the wheat was of poor quality, containing a large 

 percentage of barley and other contaminating factors, so that a
