1 Determined for urine spilled. See p. 243. 



In the records of the nitrogen output during fast given in table 196, 

 aside from the uncorrected low figures of the Naples fast of Succi, the lowest 

 nitrogen excretion is 5.67 grams on the second day with " J." The observa- 

 tions during the earlier days of fasting of so low an amount of nitrogen 

 in the urine of the subjects " J " and " S. A. B." are strikingly exceptional. 

 Even with the fasting girl, Flora Tosca, presumably of smaller body-weight, the 

 nitrogen excretion is larger than in the two instances cited above. 



The largest amount of nitrogen excreted on any fasting day in the Middle- 

 town experiments is 15.04 grams on the third day of experiment No. 69.
