that the gales experienced were as muck owing to the monsoon as to 

 the local effects of the hurricane. In my first Memoir, I have given a 

 Chart fully explaining how this should occur, and really did occur on 

 these same days in 1839, (3rd to 7th June,) at the setting in 

 of the S. W. moonsoon of that year, which I find has been quoted 

 by Professor Dove of Berlin, as exactly tallying with his theory 

 of the causes of these atmospheric disturbances.* The object of 

 our present researches is not so much to trace out the causes of 

 storms, as to chronicle exactly the facts and other evidence; but 

 I allude to this as necessary to be held in remembrance by those who 

 may follow me in the attempts which I make to shew the causes of 

 apparent anomalies when they occur. 



Result. 



To those who may not have the time to go through the foregoing 

 details and summary of our evidence, the following brief notes of the 

 Results of our inquiries relative to this remarkable storm may be 

 acceptable. I have endeavoured to distinguish in them clearly the 

 degree of certainty to which I think each separate head is entitled. 

 It appears then that, 



1. From the 28th to the 31st May there seems to have been, in the 

 S. Eastern and Eastern parts of the Bay, some considerable atmos- 

 pheric disturbance, probably accompanying the setting in of the S. W. 

 monsoon ; but as far as we are informed, nothing which could be cer- 

 tainly called a rotatory storm, though it is highly probable that the 

 John William Dare experienced on the 30th May the Eastern qua- 

 drant of the Cauvery's storm noticed in the next paragraph. 



2. But on the 31st May, by which time the Barometer at Calcutta, 

 where the weather was fine, had already fallen 0.14 below the average, 

 the H. C. P. Vessel Cauvery had a true rotatory gale increasing to 

 a hurricane at midnight of between that day and the next, and 

 moderating at noon of the 1st June. This storm, which I have called
