Remarks.—This experiment, which represents the preliminary period of 
metabolism experiment No. 5, began with breakfast April 26, 1897. It differs 
from most of the digestion experiments in continuing eight days instead of four. 
The subject was engaged in his usual duties, which were not arduous. He 
might be considered in this case as having light muscular exercise. ‘The follow- 
ing table shows the income and outgo of nitrogen in this experiment:
