Experiment III. July 5th to July 17th. 



This was in reality two experiments in one, and must be considered 

 in two separate periods, viz., from July 6th to July 12th inclusive, and 

 from July 6th to July 17th inclusive. 



1st Period. 



The Nitrogen. — Again an unmistakable increase in the nitrogen 

 discharge is to be noticed. The daily average after the work exceeds 

 the average before the work by 1'26 grams ; the reserve of nitrogen 

 was reduced from 11*62 grams to 10*41 grams, a loss of 1*21 grams, 

 which was more than made up the next day. The close correspon- 

 dence with the diminution occurring in Experiments I and II is 

 worthy of note. 



The Phosphoric Anhydride. — The increased discharge after the work 

 is very marked, but the total quantity ingested in the time is by no 

 means accounted for, as the following figures show : —
