434 Reduction of Meteorological Tables in the Doab. 



From the 8th to the 14th of February, it is stated, cloudy weather 

 accompanied by thunder and lightning without rain prevailed, but 

 it is to be regretted, that the same kind of observation has not been 

 again repeated. The electrical condition of the atmosphere, in so 

 far as that is indicated by the duration and intensity of thunder- 

 storms, is a point of much interest, and one that has occupied the 

 attention of Meteorological observers, far less than its importance 

 merits. The curious relations and analogies subsisting between heat 

 and electricity, lead us to anticipate that we may yet trace some 

 marked connections between the indications of the Thermometer 

 and those of the Electrometer, and it would be well worth the while 

 of observers to pay special attention to this subject, to enter in their 

 Registers the epochs and duration of thunder-storms during the year, 

 and to record all such particulars relative to them as in their opi- 

 nion would prove of interest and use. Theories on the distribution 

 of electricity throughout the atmosphere in Polar and Equatorial 

 regions have been broached, which cannot possibly be either esta- 

 blished or refuted, save by observations made throughout extensive 

 areas, and continued for considerable periods. These, India affords 

 peculiar facihties for making, and I yet trust to see them generally 

 and extensively in active progress.

The Southerly winds, including under this expression South 

 Easterly and Westerly, prevailed during the present year to a much 

 greater extent than during the preceding one, especially during the 

 rainy months of August and July, when out of 62 days, 37 had winds 

 of the above description. The proportion of rainy days to those 

 without rain increased also from 1.14 to 1.7, or double, and the quan- 

 tities of rain that fell were nearly as 1 to 3, that of 1838 being three
