Hygrometrical Observations made at Bancoorah in Beng'al. 

 By George Macritchie, Esq. Communicated by the 

 Author. 



Sir, 



In the communication I had the honour of transmitting to you 

 on the 12th March 1832, I mentioned that I had kept no regis- 

 ter of the hygrometer at Bancoorah. But I find a connected 

 series of hygrometrical observations for a twelvemonth at that 

 place, which I now feel pleasure in sending to you. 



Table. 



, April 1828 was parching weather throughout ; but unfortu- 

 nately I did not remark the hygrometer before the last day of 

 that month, when at noon the dew point was 76°.50, the tem- 

 perature of the room being 91°.50, shewing a difference of 13% 

 the greatest I ever observed. 



The average monthly range of the thermometer and of the 

 barometer, whilst I kept a, register at Bancoorah at the hours of 

 observation, is subjoined as under.
