the N. W. Provinces, the rainfall of this year was deficient. I may here 

 point to a parallelism between this case and that of the rainfall in cyclones, 

 in which it appears, by the common consent of observers, that the greatest 

 rainfall occurs in advance of the cyclone-centre. 



Now something similar to the above relation seems to be traceable in 

 other cases when the depression is less intense and the effect more extensive, 

 In 1873, although the fall was deficient in Bengal and the N. W. Provinces, 

 it was not so in the Punjab nor about Eoorkee and Agra, which lay to the 

 west or north-west of the abnormal depression in Oude ; that is to say, be- 

 yond the depression in the course followed by the vapour-bearing winds. It 

 was very copious also in Burmah, which lay beyond (to the north and north- 

 east of) the Nicobar depression, the monsoon-current here being from the 

 south west. In 1871, when there was an abnormal depression in the east 

 of the Bay, in Orissa, and about Jubbulpore ; (how far this last may have 

 extended east and west we do not know, in the absence of stations) ; the 

 rainfall was abundant in the Gangetic valley and Bengal, as well as the 

 Central Provinces. But on the other hand, we must not lose sight of the 

 fact, that in 1S72 and 1873, when the depression was as great or greater in 

 the Bay of Bengal and Orissa, the rainfall in Bengal as in Northern India 

 generally was light or very deficient. This fact warns us that we must not 

 push too far the conclusions drawn from our present imperfect data. 



The mean or normal values adopted as standards in the following tables 

 are those of all registers up to the end of 1874. The number of years in 

 each case is from 5 to 8. The table of these values is given at page 15 of 

 the Meteorological Report for Bengal for the year 1874.
