[No. 4, 



the rainfall at Cherrapoonjee. Owing, probably, to the indraught which 

 these Central Asian storms cause up the Brahmaputra valley, there has 

 been in all cases which I have examined, an increase, at times a very 

 great increase of rainfall at Cherrapoonjee. I do not wish it to be un- 

 derstood that in the occurrence of such heavy rainfall there is proof of a 

 disturbance in Central Asia, but when the rainfall cannot be accounted for 

 by any changes proceeding over India, and the other characters of Hima- 

 layan storms can be traced, the rainfall affords a valuable item of evi- 

 dence. I give in a table below the rainfall for June and July, from which 

 it can be easily seen that there were, during that period, six occasions of 

 increased rainfall, the most noticeable being the falls of 24 and 21 inches 

 on the 9th and 10th July, with the storm I have described above. The 

 other dates approximately were June 10th, June 16th, June 22nd, June 

 29th, and July 20th.
