1078 A Seventh Memoir on the Law of Storms in India. [No. 131. 



ally a Southerly gale on the 31st, with a heavy cross sea ; her Barome- 

 ter falling from 29.50 on the 30th to 29.30 on the 31st, when she hove 

 to. If this was the beginning of the rotatory storm, which I have 

 called the Cauvery's storm, (see Chart,) as it may well have been, this 

 change of wind is exactly what should have occurred, and the fall of 

 the Barometer and heavy cross sea confirm the probability, that it 

 was the North Eastern part of the vortex which she met with. 

 The Norfolk, which was four degrees to the W. by S. of the John 

 William Dare, had also threatening weather, with wind from the N. 

 N. W. becoming N. W., as she ran to the Southward, she being on the 

 S. W. quadrant of the storm, if there was one. At the Sand Heads 

 and False Point, we find by the logs of the Pilot Vessels, that the 

 winds and weather were gloomy, squally, and threatening a gale from 

 the Eastward, with their Barometers falling (Coleroon and Beacon's), 

 while to the Southward we find the Algerine and Ariel with heavy 

 weather (or the monsoon ?) from the W. S. W. and S. S. W. This 

 state of winds and weather all over the Bay is also, it will be noted, 

 that which we might suppose to occur at the first part of a rotatory 

 motion occasioned perhaps by a struggle between the N. East and S. W. 

 monsoon, which last, as we see by the log of the John Craig, was appa- 

 rently blowing strongly up from latitude 6° N. We cannot assign any 

 place for the centre of the storm, but if there was one, it was doubtless 

 between the position of the John William Dare, Point Negrais, and 

 the Norfolk. 



21st May. — It was at noon blowing half a gale from N. E. by N. 

 to N., increasing to a gale from N. N. W., and to a hurricane at mid- 

 night, with the H. C. P. V. Cauvery, which stood to sea from her 

 station off False Point and to the S. E. of it, off Conjong Bay,* where 

 she hove to. With the Light Vessels also a gale had set in from 

 E. to E. N. E., though at Kedgeree, the weather was only threatening, 

 and at Calcutta there was nothing remarkable, as to the wind and 

 weather, to common observers; though the Barometer had fallen from 

 the average of 29.64. to 29.50. 



The ship Augustus had the commencement of this storm, (which as 

 felt most strongly by the False Point station vessel, we may call the
