A Second Memoir with reference to the Theory of the Law of 

 Storms in India ; being, Researches relating to the Storm of 

 the \9th to the 2\st September at the head of the Bay of 

 Bengal; to the Great Hurricane at Coringa on the 16th Novem- 

 ber, 1839 ; and to another off the Island ofPreparis on the 22d 

 November. By Henry Piddington. 



PART I. 



My first Memoir on this subject, published in the Journal 

 of the Asiatic Society for July and August 1839,, was occupied 

 with the Gale and Hurricane of 3rd to 5th June of 1839, with 

 some theoretical and practical deductions. In the present, I 

 propose to consider the tempests which occurred in the Bay 

 of Bengal, between that epoch and the close of the same year. 

 The first of these is the Gale of 19th to 21st September 1839. 



The authorities from which my information respecting it is 

 derived, are the logs and reports of about fourteen ships, Pilot, 

 and Light Vessels, and 10 or 12 reports from inland stations, 

 which have reached me through the Secretary to Government, 

 pursuant to the notice published in the newspapers on 11th 

 September, 1839. 



I proceed, as in the first Memoir, to place upon record the 

 materials, abridging them when necessary ; after which I shall 

 arrange them in a tabular form for each day, so as to afford 

 thereby at a glance, as well as by the chart, a synoptical view 

 of the progress of the storm.
