The most intense hot winds were on the 21st February 

 and the 8th of December. On the former day the sky was 

 cloudless, but covered with a haze of a smoke-like appear- 

 ance, through which the sun shone with a lurid glare ; the 

 air at the same time being extremely oppressive and sultry, 

 and the wind in blasts as from a heated furnace. The 

 evaporation was enormous ; and a Thermometer, with its 

 bulb kept moistened with pure water, showed 67°, with the 

 surrounding air at 100°. The hot wind of 8th December 

 was equally intense in its character.
