44 Fifteenth Memoir on the Law of Storms. [Jan. 



The following are the views and data upon, which I estimate the 

 places of the centres of the storm for the different days, as I have 

 placed them on the Chart. 



The first Logs we have are those for the 13th April, on which 

 day, or rather at midnight, between the 13th and 14th with the 

 East London a gale is stated to have fairly commenced, which by 4 

 a. m. is called a hurricane, from N. W.,* which by noon of the 14th 

 had veered to "W. N. W. 



Now, at noon of the 14th, this ship had the Buckinghamshire about 

 145 miles to the W. N. W. of her, with nothing more than a strong 

 breeze from N. W. b. N., and the Atiet Rohoman at anchor at Allep- 

 pee, 140 miles to the North Eastward, with an E. S. E. breeze, and 

 fine weather. If the East London's was at this time a rotatory storm, 

 we must then infer it to have been one of small extent, since its centre 

 would have been about N. E. from her, and have thus been at about 

 half the distance between her and Alleppee, if only 140 miles in dia- 

 meter ; but it evidently did not reach that anchorage. If we call it 

 then one of this class for this day, and suppose it the commencement 

 of that of the following days, it did not exceed, if it reached to 100 

 miles in diameter ; and indeed the only fair grounds we have for doing 

 so are the regularity of fall of the East London's Barometer, and the 

 gradual veering of the wind from N. W. to W. N. W. and W. S. "W. 

 on the 15th. 



On these grounds, then, I have marked for this day, the 14th, a small 

 dotted circle, (as being somewhat doubtful,) of 100 miles in diameter, 

 and which leaves still a space of 45 miles to the anchorage of Alleppee, 

 and of 1 1 miles to the position of the Buckinghamshire, which vessel 

 had but a strong breeze and cloudy weather, and her Barometer yet as 

 high as 29,72 at 1 p. m. Indeed, I am much inclined to take this 

 N. W., "W. N. W., and W. S. W. gale as nothing more than a strong 

 precursor of an early monsoon, the tendency to North "Westerly winds 

 in March and April on this part of the coast being well known, f and 



* This vessel was in much distress from leaks, and evidently was a bad sea boat, but 

 she lost only a foretopmast, with small spars and sails, and repeatedly, (as far as can be 

 inferred from her very incomplete log) hove to and bore up ; which shows that the 

 weather allowed her to remain quite manageable, and was by no means at hurricane 

 force.
