* Exclusive of the protein contained in the mUk, which varied but 

 slightly. 



We observe that after tlie quantity of protein digested reached 

 150 grams daily there was practically no further increase in the 

 protein stored up in the body, even though the amount in the 

 food was still further augmei^ted. 



That an exclusive protein diet will not produce body tissue is 

 well illustrated in the so-called '^ Banting cure" for obesity, 

 where the patient is put on a meat and fruit diet, especially the 

 former, with no potatoes, butter, or bread. 



Pfliigeri has shown that a hard- worked dog fed on ''almost 

 fat-free" meat diet can live on that food alone for seven months, 

 and on the basis of this experiment concludes, contrary to the 

 views of Voit and other authorities, that nitrogenous compounds 

 may sustain life for an indefinite period. 



65. Influence of previous feeding. — Beside the supply of pro- 

 tein in the food, the protein consumption in the body is dependent 

 upon another factor, viz., the condition of the body of the animal 

 as a result of previous feeding. It clearly appears from experi- 

 ments made in this line* that when a change in diet occurs the 

 consumption of protein will increase or decrease according to the
