424f Reduction of Meteorological Tables in the Doab. 



Thermometer displayed is suspended against the cross wall of the 

 northern verandah of the Canal bungalow, and except in so far as an 

 easily permeable chick door may interfere, is freely exposed to the 

 atmosphere. 



As in the case of the Kulsea observations, I propose discussing the 

 Thermometric observations first, and afterwards the Pluviometric 

 series, with the state of the weather, &c. I regret it is not in my 

 power to apply some necessary corrections to the first mentioned 

 class ; but as I may probably yet have an opportunity of ascertaining 

 the precise amount of these, I will now confine myself solely to 

 the registered results.
