It follows from the last table that the exponent of the funo 
tion of height varies as the temperature of the season, or

The whole may therefore be put under the form d — p h lw 
and the value of the coefficient p may be determined from the 
following table:

The last column shows how nearly the value of the coefficient 
p is represented by a function of the temperature of the season. 
By using a constant the agreement becomes very close,
