378 Nineteenth Memoir on the Law of Storms. [No. 5. 



rations that there really was a smaller precursor Cyclone in his wake 

 as he supposes, on the 21st and 22nd, and that it passed near to the 

 Hardwicke by the imperfect newspaper notice which I have obtained, 

 that ship being only 25 miles to the South a little East of the Futtle 

 Rozack. 



On the 23rd of April. — Taking the ships now from the Westward* 

 we see that the Deborah had on this day a small Cyclone centre crossing 

 her which is called a hurricane, and lasted for four hours only. It is 

 difficult to say from such scant information if this had any relation to 

 the next ship's hurricane, the Pemberton, which appears from Mr. 

 Meldrum's account to have had the centre of the Cyclone passing over 

 her not far from the spot of which he has given the Lat. and Long, 

 on the 22nd, but as we are quite in the dark as to whether she was 

 running or hove to ; and as the copy of his letter sent me from 

 Bombay differs from the newspaper report, we can merely take the 

 whole as a sort of confirmation, but nothing else. The shift given by 

 the newspaper report, N. N. W. to W. S. W. would also give a Cyclone 

 track to the S. E. like that of the Deborah; and as the Pemberton was 

 a cotton-laden ship bound to England, she probably ran on as long as 

 she could do so under the temptation of the fair wind from N. N. W. 

 I should take the Deborah's to be a separate Cyclone of small dimen- 

 sions, but it is scarcely possible to trust to these scant, and so frequently 

 erroneous newspaper notices. 



We have next the Log of the Lady Sale, but unfortunately her 

 positions are only given on the 21st and 24th, and the extract from 

 her log giving no distances run, or rate of drift, I cannot work up the 

 dead reckoning. We can only then estimate roughly that as her track 

 and drift cross that of the Cyclone, and as she was evidently hove to 

 close on the western verge of the centre at 4 p. m. on the 22nd, she 

 had probably run down about 200 miles from her position on the 21st 

 before she hove to ; which would place her at that time, i. e. 2 a. m. 

 23rd, in Lat. 9° 44' S. ; Long. 83° 43' East, when, as the wind is 

 marked due East in her log, she had the centre North from her, and 

 between this time and noon of the 23rd the centre, as we see from 



* Because from the shifts given in the notices of the Deborah, Pemberton and 

 others, N. E. to S. W., it is clear that their Cyclone was travelling to the S. East' 

 ward ! a very unusual track, but one fully shewn to be correct by all the Logs.
