Influence of Inanition on Metabolism. 



The quantity of preformed creatinine on the contrary, is seen to diminish 

 as the fast progresses. In general, the diminution is quite regular for the first 

 4 days of the experiment and indeed, when the results for experiments Nos. 

 75 and 77 are compared, the agreement between the two experiments is remark- 

 able. On the fifth day of experiment No. 75, the lowest excretion of preformed 

 creatinine is observed. After this day, the excretion increases slightly until 

 the end of the experiment.

with and without food. 



1 In terms of creatinine. 



3 Does not include possible amount in urine lost. 



While the quantity of preformed creatinine gradually diminishes as the fast 

 progresses, the amount of creatine, which in normal urines is extremely small, 

 gradually increases, and on the sixth day of the fast (No. 75), there is excreted 

 0.585 gram of creatine (expressed in terms of creatinine).
