Here, as in tbe Nilgberry Hills, tbe temperature of the earth, is ia 

 every month above that of the atmosphere, excepting in March. The 

 desorepancy, as in lower situations and higher latitudes, is in favour of 

 the earth being on the average warmer than the air, but more especially 

 so 'va. winter. They nearly coincide in March and August. 



VII. — Tempekatuee op the Eakth and op the Am in the Plains op Behsai. 



At Dacca, lat. 23° 50', and 72 feet above the level of the sea. Dr. Joseph 

 Hooker found the temperature of the earth at the depth. of two feet 

 seven inches was 84°, in the end of May ; and the mean temperature 

 of the air ranged at the same time from 75-3 to 95-5 ; its mean therefore 

 nearly corresponded with that of the earth. At ten stations in these 

 plains, varying from 72 to 131 feet, above the level of the sea, the 

 mean of the indications of the ground thermometer during May was 

 85-53 ; the approximate mean temperature of the air was 82-30 ; the 

 difference therefore was only 3-23.
