ratios oresentel in the rest to the last line of the talole 

 are obtained. iSach ratio represents the iTiagnitude of th-: 

 range of variationy of the olinatic index that it represents 

 for the eight stations in question. The average ratio value 

 for these periods is given in the last li.ne . It thus appears 

 that the geographical range of variation in the temperature 

 efficiency index is marl-edly less than is the corresrionning 

 range of variation in the index of either sunshine or evapo- 

 ration. This relation holds generally througho;:t the season. 

 In short, the temperature efficiency values exhibit a smaller 

 degree of geographical or Iceal variation than is exhibited 

 by the index for sunshine and the evaporating power of the 

 air .
