was attained in the chamber in the shelter, and on August 27, 

 the same condition was reached in the glass box. The numerical 

 results of this series are given in table VI, which is essentially 

 uniform with the tables for the preceding series. 



Series V furnishes another case where it is strictly true that 

 the five main averages of soil moisture residue show an increase 

 with increasing atmospheric evaporating power. It can be readily

noted, however, that average (3) is relatively too low to be joined 

 with the others on a consistent curve. 



The detailed relations between the different quantities involved 

 in the results of this series are shown in the graph of figure 5, 

 which is plotted uniformly with the preceding graphs. 



The generalized cm've of figure 5 was derived from the log- 

 arithmic equation heretofore employed, with the constant ratio
