In Table II are given the averages for the twenty years at 

 both stations, and in Table III, the differences in the average 

 values at the two stations, those at the lower station being taken 

 as the standard of comparison, and the + and signs indicating 

 that the values at the higher station were higher or lower, 

 respectively, than those at the lower station. These differences 

 have been worked out to one place further than the values 

 entered in Tables I and II.

wet and dry bulb thermometers for determining the humidity 

 of the air read at 9 a.m. every day were fixed in Stevenson's 

 screens, 4 feet above the ground : the earth temperature (E.T.), 

 likewise read at 9 a.m., was determined at 6 inches below the 

 surface, and the minimum radiation thermometers were 4 inches 

 above the surface of the bare earth. 



The rainfall for successive years, taking the year from November 

 to October, as well as the ordinary calendar year from January 

 to December, is given in Table IV. The rain gauge was a 

 five-inch gauge placed 8 inches above the surface of the soil.
