period, shows a rise in the rate in favor of the B’ and BC’ 
sprayed plants, followed again by day intervals in which the 
normal is approached. It was this series in particular, which 
was conducted prior to series B, which suggested so definitely 
the importance of conditions in modifying the amount of the 
transpiration quantities after spraying. In the preceding
