354 Dr. Parkes — Further Experiments on the [Mar. 2, 



On the 8th day there was a large stool, showing previous accumulation. 

 Taking the weight of all the stools during the two sections of 10 days, and 

 using the percentage composition of nitrogen of the one day in each series, 

 the mean daily excretion of nitrogen was 1*807 gramme in the 1st section, 

 and 1'766 gramme in the 2nd section of 10 days. 



The pulse and the temperature of the axilla were taken every two hours 

 from 6 a.m. to 10 p.m. The temperature is in Fahr. degrees : —

The effect on the pulse of the exercise from 6 to 8 in the 2nd period was 

 interesting. The exercise brought up the pulse 16 beats at 8 o'clock over 

 the corresponding period ; but the pulse afterwards fell below the beats of 

 the 1st period, and the result was a perfect balance of the day's work, so 

 that the mean pulse of the day was the same in both periods. This shows 

 how completely the heart, if called on for exertion, compensates itself by 

 subsequent rest. The exercise made little difference in the temperature 

 of axilla or rectum ; there was a slight rise at 8 a.m. corresponding with 

 the pulse after exercise in both axilla and rectum, but the mean of the day 

 was the same. 



Second Series. 

 Prepared concentrated food. 

 It was proposed to give prepared food of uniform composition, so that 

 the daily ingress of nitrogen would be absolutely constant. I was unable 

 to obtain the "pea-sausage" which the German troops are now using in 

 the Field, and used instead a concentrated food which had been sent by an 

 inventor to Sir Galbraith Logan, and by him sent to Netley for report.
