800 Ninth Memoir on the Law of Storms in India. [No. 141. 



In reply to some enquiries, Mr. Branch Pilot Sharling favours me 

 with the following Note relative to the Westerly set which prevails 

 in these Gales. 



The reason that the rate of current was left out in the logs, is, that 

 I thought it would be of no use, but as you wish for it, the set run 

 to W. N. W. on the flood, and on the ebb to W. S. W. from 3 to 3£ 

 knots. 



The et Megna" has no Barometer on board. 



SUMMARY. 



/ now proceed to state the grounds on which I have laid down the 

 track assigned to these Storms on the Chart. 



On the 1st October. — Commencing from the Southward, we find by 

 our tables that the Lion in 13° N. had nothing but a strong W. S. W. 

 monsoon, but the Essex in 16° N., longitude 83° 50' E. at noon had a 

 falling Barometer from 29.836 to 29.586 at midnight with the wind 

 increasing to a N. N. E. gale at that time. At Pooree and Cuttack 

 the storm commences also "at night" on the 1st, with strong breeze 

 from the North, and the Eliza standing to sea, was at midnight in 18° 

 30'* N., longitude 89° 0' E. with her gale commencing also at N. N. E. 



Of these data, the Lion's breeze was doubtless the monsoon, and the 

 variable squalls of the Essex from W. S. W. to N. N. E. at midnight, 

 the first effects of the storms, which as the ship was only 80 miles from 

 the high land of Vizagapatam and the ranges of hills close to and at 

 the back of that part, were probably deflected to a N. N. E. instead of 



* I take this latitude as set down, but it seems to me at least 20 miles too far to the 

 Southward, for the Eliza on 30th September, at 7 p. m. had the Light Vessel bearing 

 North, let us say at most 15 miles. She had then to midnight light baffling airs from 

 North to South alternately, when she could not have made more than 10 miles more 

 of Southing, or 25 miles from the Light Vessel in all. On the 1st, she had an increasing 

 breeze of about 5 knots to 3 p. m. when she hove to, calling this 15 hours' run and 

 at 6 knots it is but 90 miles, in all 115 miles. From 3 p. M. to midnight she was hove to, 

 and allowing her to have made 2 miles per hour of Southing, or say 18 miles, this is 

 but 133 miles in all, and part of it on a S. S. E. course. Now from the outer Light 

 Vessel in lat. 21° OV to Lat. 18° 30' there is a difference of 154 miles of latitude ; while 

 as above, we can make at the most but 133. 1 think this must have been an error 

 of the copyist, but have taken it as set down, being always unwilling to assume 

 errors in documents, unless they are evidently against common sense.
