1046 Third Memoir mith reference to [No. 106. 



The Tenasserim seems but just to have felt the first pufFs of the 

 storm on this day. 



It will be remarked in the table for this day, that the Ganges in 

 Lat. 7° 10' N. Long. 95° 18' E. was hove to from the day preceding, 

 in a heavy gale blowing "from SSW. to SW." The chart does not 

 admit my including her position, but if projected, it will be found that 

 if the circle of the storm was completed, she was abouj: on the opposite 

 side of it from the Nusserath Shaw ; and I have thus, with reference 

 to the rate of travelling of the centre of the storm, between the 2Hth 

 and 29thf assumed that it may have been about half way between 

 them, or 290 miles from each. This would give it a circle of 580 miles 

 on the first day, and we have no better authorities. The brief extract 

 from the log of the Clarissa which vessel it will be seen, could 

 not be far from the same latitude* on the 21 th; being on the 2^th 

 in 7° 1' N. but seven degrees further west; (her Long, being 87° 

 6Q' E.) gives us "blowing hard from West to WSW.," so that there 

 was probably, as in the gale of June, 1839, a Westerly and South- 

 westerly gale blowing across the mouth of the Bay, while the vortex 

 was forming and travelling over from the Andamans to Cuttack. 

 " The fine weather and SE. breezes" of the Flowers of Ugie and 

 Christopher Rawson are exactly what should occur on the northern 

 arm of a parabola formed by the deflection of a heavy SWesterly 

 monsoon, setting in from the Bay against the high land of the Ma- 

 lay Peninsula. 



For the 2Sth April. If we take the storm to have now travelled 

 at the rate of 7 miles an hour, its centre at noon may have been 

 about 15 to 25 miles SSE from the Nusserath Shaw; since this 

 ship had, at 3 p.m. the shift of wind from ENE. to SW. as shown 

 by her log ; so that the centre must have passed near her, to the 

 Southward, or even over her. The Tenasserim at 1 80 miles distance, 

 had the wind at SE. " a heavy gale" though if this was the hurricane, 

 she should by her position, which is nearly due north of the Nusserath 

 Shaw's^ have had the wind at East. As there can be no doubt 

 about the Nusserath Shaw having had the centre close to her 

 at noon, and that her position was not far wrong, I have taken the 



* Being bound from. Penang to Madras, she had to make a westerly course across 

 the Bay.
