34 John Eliot — On the occasional Inversion of the Temperature [No. 1, 



Bengal, the maximum temperature was considerably below the normal in 

 Upper India (the deficiency being most marked at the hill stations), 

 and was much above the average in Bengal, Behar, and the greater part 

 of the North-Western Provinces. In the hill districts the maximum 

 temperature was lowest on the last day of the storm and rapidly in- 

 creased during the next few days, so that at Simla on the 5th, when 

 the snow was nearly all melted except in sheltered spots, the maximum 

 was slightly above the average. The most important fact is that the 

 lowest day temperatures in the plains were not recorded during the 

 passage of the cloudy weather of the storm, but on the first two days of 

 cloudless skies and fine dry weather which followed the storm. The 

 greatest depression of day temperature occurred at Lahore and Roorkee 

 on the 2nd, at Lucknow on the 3rd, at Burdwan and Calcutta on the 4th 

 and 5th. This transmission of the cold wave corresponds to the rate 

 of transmission of the storm itself, which roughly averaged from 250 to 

 300 miles per diem, or 10 to 12 miles an hour.

 ture. (The data are of the night preceding 8 A. m. of the day named.)
