sent the percentage of decrease in dry weight of material. The 
last weighing in these cases unavoidably included the dry weight 
of fungus material formed, so that the figures are higher than they 
ought tobe. The differences in weight in these cases give only com- 
parative values of the amounts of material respired by the organ- 
isms. ‘The filter paper used was the best Swedish paper, and the 
cork was obtained by skinning steamed potatoes, scrubbing the 
skin thoroughly, boiling it for 48 hours in distilled water, extract- 
ing for 48 hours in ether, and then boiling again with water. All 
figures represent averages, the composition of these figures being 
Shown in tables VI and VII. In many cases there was a fair coin- 
cidence of the values, while in others a great disparity appeared. 
The averages probably would more nearly approximate the true 
value if a greater number of figures were available.
