4. — Daily rate of Evaporation in Calcutta. 



On the chance of its proving serviceable to some speculator in meteo- 

 rology, we place on record the subjoined statement of the daily rate of 

 evaporation in Calcutta for the year 1845. The instrument employed 

 was that described in Volume XIV. page 213; it was freely exposed 

 in an open verandah to the influence of the atmosphere, sheltered, 

 however, from the direct rays of the sun.
