Whereas with N. there is a lack of uniformity in the respiratory 

 quotient, a gradual decrease is to be noted on v. H.'s alcohol days; 

 in the afternoon however the original value returns. 



Since the experimental evidence here reported goes to show that 

 alcohol exalts the economy of muscular activity, at least at the 

 outset, and since, as stated heretofore, it appeared from our previously 

 published experiments that a high temperature renders muscular 

 work less economical, we have endeavoured to ascertain whether 

 this unfavourable influence could perhaps be arrested or lessened by 

 alcohol, in other words we have tried to solve the question as to 

 whether alcohol has any action on respiratory exchange during 

 muscular exercise and at a high temperature. 



These experiments were in every respect conducted as described 

 above. Particular attention was given to keeping the room-temperature 

 well above the limit found by us heretofore (21.5°) and also to 

 keeping the relative humidity approximately constant and corre- 

 sponding to that of the lower temperatures of from 50° — 60°. 



The following averages were found: 

 N. at a mean temperature of 28° C.
