The Data on which we have to depend 



estimate of 8-41 inclies as the average watershed for Eng- 

 land, and by correcting this amount for the difterence ot 

 tempei ature, I conchided that four and a half inches would 

 represent an approximation to the watershed ot the i lenty 

 basin.

 Proportion of the Kain evaporated, and the Watershed and tlie 

 Evaporation from Water in the different months in England, accord-
