Alcohol and Exercise on the Body.

If we adopt the two last rest periods, which are nearly alike, as the 

 standard of the usual alvine excreta under this diet, the muscular work 

 (digging), hy acting mechanically on the bowels, caused a greater discharge 

 both of the solid parts of the excreta and of water ; much of the difference 

 of the nitrogen, and perhaps the whole, is thus accounted for. 



It was very remarkable how uniform the excreta were in the per- 

 centage of water when the means of the periods are taken, though from 

 day to day there was considerable variation. It will be seen how much 

 larger the excreta were than is usual in meat-eaters, and how much ni- 

 trogen passed from the bowels.

Acidity.

Phosphoric acid 



Free acidity (taken 1 

 as crystallized oxa- I 

 lie acid) J 



The phosphoric acid was not affected in the first exercise period ; it 

 was slightly increased in the alcoholic, but the difference may be too slight 

 to be material. The chlorine was rather lessened in both exercise periods : 

 the free acidity was slightly increased in the brandy period over the 

 exercise period on water ; but the change was so slight as to be within 

 the range of daily variation. Exercise on water exerted no marked in- 

 fluence on the free acidity as compared with the periods before and after. 



4. The Pulse*. 



The pulse was taken every two hours after the man had been in a 

 recumbent position for at least fifteen minutes. 



* The pulse and temperatures were taken with very great care by Serjeant Turner of 

 the Army Hospital Corps.
