surface on this day beyond a strong remnant of the monsoon. I 

 say here "at the earth's surface" because I think it quite probable 

 that the Cyclone may have been formed and in action overhead, and 

 not far from the Ararat's position, though it had not yet descended. 



On the list Oct. — We have the Ararat bearing up at 5 a. m. 

 with the wind at South, and running up to the N. N. W. with a fine 

 breeze at Noon, when she again had it S. S. W. and by sunset it in- 

 creased to hard squalls ; at midnight it was a hard gale with which 

 she was running 10 knots, being then at midnight in 18° 35' N. and 

 Long. 87° 23' East with the wind about S. b. W. veering to South 

 at 3 a. m. on the 22nd. "We have also for this day the LucJcnow's log, 

 which ship on the 21st, at noon had a heavy gale which had veered 

 from N. E. to W. N. W. as she ran down and hove to, showing that 

 she was on the Western side of her Cyclone, while the Lord Petre 

 in nearly the same latitude but 130 miles to the Eastward of her, 

 was hove to with a heavy Southerly gale showing that she was on 

 the Eastern side of it. To the Northward, the Georgina just leaving 

 her pilot, found the weather becoming worse, with more suspicious 

 appearances as she stood to the S. W., her Barometer being unsteady 

 and the sea coming up from the S. East. The Pilot vessel Tavoy 

 and the ship Scour field, at the pilot station had it blowing fresh, and 

 with the Tavoy hard, from E. S. E. to S. East, though the Tavoy' s 

 Barometer was yet 29.84 to 29.80. 



From this it appears clear that there were two Cyclones formed on 

 the 21st, both travelling up on tracks between North and N. N. W. 

 the Western one of which passed over the Light House at Ealse 

 Point; at 8 A. m. on the 22nd, being at Noon on the 21st between 

 the Ararat and the shore ; its centre lying then in about Lat. 17° 

 30' N. and nearly on the meridian of the Light House at 176 miles 

 distant from it, and this Cyclone we may, to distinguish it, call the 

 Light House Cyclone. The other, or Eastern one, I consider to have 

 its centre between the tracks of the Lucknow and the Lord Petre 

 or between the meridians of 88° and 90°, its centre being at Noon, 

 also on the 21st, in about 19° 12' North and, say, 118 miles S. S. E. 

 of the Moating Light Vessel station. The heavy Southerly gales of 

 the Ararat may, it is true, have been, for a time at least, the remainder 

 of the monsoon, but there seems no reason to doubt that, if not
