first period, and we shall therefore use chiefly the data of that period in 

 the discussion. 



During the first period extending from the 1st to the 4th the mini- 

 mum temperature was on every night several degrees higher at the hill 

 stations than at the adjacent plain stations. The minimum temperature 

 on the night of the 3rd for example was 12^° higher at Murree than at 

 Rawalpindi, 3° higher at Simla than at Ludhiana, 5° higher at Mussooree 

 than at Roorkee, and 10° higher at Ranikhet than at Bareilly. 



The following method of stating the facts will shew that the in- 

 version of the temperature relations was not confined to the neighbour- 

 hood of the hills only. On the night of the 3rd (or early morning of the 

 4th) the minimum temperature at Murree,- Simla, Ranikhet, and Mussoo- 

 ree was higher than at all the plain stations in the Punjab, North- Western 

 Provinces (except Jhansi), Rajputana, Sind, Central India, and the greater 

 part of Behar and Bengal and the Central Provinces. 



The following statement gives exact data for representative stations 

 in each province.
