Cauvery's storm,) from the N. E., but it must have been of small ex- 

 tent, for it did not reach the Panthea, which vessel was about 90 

 miles due West of the Augustus at noon ; and hence we may also de- 

 duce, that the Easterly gale felt by the outer Light Vessel was also not 

 truly a part of it, but probably the combined effect of the Monsoon, 

 the disturbed weather felt in the middle of the bay by the John Wil- 

 liam Bare and Norfolk, &c, and of the outskirts of this small vortex 

 I have placed the centre of the Cauvery's storm in latitude 18° 20' N. 

 longitude 87° 53' E. ; but it may have been farther to the Southward, 

 for no log was kept of her run to sea, nor of her drift when hove to. It 

 was the 3d before she got back to sight the land off Ganjam. 



1st June.~—From midnight the Cauvery was still drifting to the 

 South, with a hurricane from North to N. N. W., which veered by 

 noon (as the centre passed to the Northward of her position,) to the 

 N. W. to W. at 8 p. m. and S. W. at midnight. This storm may have 

 exhausted itself before it reached the shore, though the Panthea felt 

 the N. E. gale of its N. W. quadrant ; but we have unfortunately no 

 account from Ganjam or Pondy, about, or to the South of which 

 places it would have reached the shore if its centre landed upon the 

 coast. At Pooree it was only felt as heavy rain on the 31st. 



The Augustus on this day had the wind veering from the E. by N. 

 to N. W. by N., confirming the evidence derived from the Cauvery's 

 log, of its having really been a small storm. I have therefore marked 

 a small circle for it, with the Cauvery's place at noon upon the 

 Chart. 



We may thus fairly allow that this was a separate storm of small 

 extent, preceding Hhat of which the centre passed over Calcutta, by 

 about 62 hours. Whether it also was the one which appears to 

 have been originating with the John William Dare, on the 30th of 

 May, or whether her storm of that date gave rise to both this and the 

 Calcutta storm, we do not know. I am inclined to think, that the 

 J. W. Dare's storm was the Cauvery's hurricane, because if its track 

 had been more Northerly, it would have brought the centre closer to 

 the John William Dare, than she seems to have had it. We have, 

 however, no right to conclude, that a rotatory storm does not at any 

 part of its progress separate into two or more storms, since (see Capt. 

 Tapley's report, 3rd Memoir, Journal of the Asiatic Society, Vol. X.
