Our endeavours to detect any influence of the seasons on the 
carbon-dioxide elimination, the tidal air, and the number of respi- 
rations per minute proved as fruitless as they had been in ascer- 
taining such influence on the oxygen-consumption. 
B. Respiratory Gas-erchange during muscular exercise. 
Little has been written as yet about the influence of muscular 
work on the respiratory exchange in the several seasons.
