1849.] Eighteenth Memoir on the Law of Storms. 827 



science, so distinctly indeed that I shall at the close of this Memoir 

 give a list of the whole of the vessels with a brief note to each, describ- 

 ing their management and what it should have been according to our 

 rules, which every sailor can verify upon the chart with the Log be- 

 fore him. This may probably offend some few individuals at first, but 

 I entreat them to recollect that it is only by pointing out their errors in 

 judgment that we can enforce, and so to say, justify our science to the 

 profession at large. They may be comforted too with the reflection 

 that fifteen years ago, had I then commanded a ship, I should myself 

 probably have been found in the list of the blunderers. 



The Cyclone cannot be said to have been felt as a heavy gale be- 

 yond Kedgeree and Saugor. At Calcutta we had nothing but the outer 

 and varying gusts of the storm circle on the 13th, 14th and 15th, and the 

 Barometer was not below 29.70, but there was quite enough to enable 

 me to announce correctly in the newspapers what had taken place in 

 the Bay, and this was soon amply confirmed by the arrival of numerous 

 dismasted vessels ; and the lessons these afforded, as contrasted with 

 those who could fairly claim credit for good management were, as will 

 be seen not few nor unimportant. 



Like the Cyclone which passed over Calcutta in June 1842, and which 

 forms the subject of the seventh of these Memoirs (J. A. S. Vol. XL) 

 the opportunity was not one to be neglected, and I have spared no pains 

 to collect every line of information which could be obtained, and I have 

 much pleasure in thanking the Public Officers of the Marine Depart- 

 ments, Merchants, Commanders and Officers of ships, all of whom with 

 the exception of two or three were most attentive to my requests, and 

 some of them most zealous in procuring from the unwilling, the dilatory, 

 or the diffident, copies of their logs and notes, or replies to what must, to 

 many I dare say, have appeared my troublesome or useless queries. I 

 have been however able to establish with confidence by the ample records 

 of this Cyclone many points of high importance to the mariner in his 

 approach to our dangerous river, so as to afford him at length a code of 

 practical directions how to manage on their approach, and to corroborate 

 much of which we had before rather inferential than direct evidence. 



In the arrangement of this Memoir as in the former ones I have first 

 given the various logs and notices, commencing with those from the 

 eastern side of the Bay in the Andaman sea and on the eastern and
