a positive increment for the total experiment was obtained of 4 grams. 

 The greatest increment in heat production was in the first period, with 

 variations above or below basal thereafter. The influence of this 

 amount of milk upon the metabolism of the subject was therefore 

 relatively slight. The urine was collected but once for the experiment, 

 and showed an average excretion of 0.86 gram of nitrogen per 2 hours.

A. L. L., March 22, 1906. The details of the experiment are given 

 in table 232. The subject drank 598 grams of milk, combined with 

 9 grams of lime-water, with a fuel value of 382 calories. In the experi-
