squalls. This would place the Cowasjee Family on the N. W. and the 

 Iron Gem on the S. West quadrant of a Cyclone at more than 300 

 miles distant from each other, the Iron Gem having drifted to the 

 Eastward, and the Cowasjee Family run up to the N. N. West in the 

 preceding 24 hours. But then these winds and consequent bearings 

 of the centre, would place it at upwards of 250 miles from the Cowasjee 

 Family to the S. Eastward and at 218 miles from the Iron Gem to the 

 N. E. b. E. though she had p. m. the wind veering to W. N. W. with 

 terrific squalls showing that if it was a Cyclone she was close to the 

 centre ; and the Cowasjee 's Barometer at Noon this day was still as 

 high as 29.76. I think then that although we might perhaps in 

 strictness say that we had but indifferent data on this day also to 

 assign any centre for a Cyclone, yet as we find it so closely following 

 up and increasing on the Cowasjee at midnight that she had then all 

 preparations for a hurricane made while standing to the N. Westward, 

 I have placed a centre for this day in 80° 42' North ; Long. 90° 28' 

 East, though this will require a large circle to include both ships.* 



On the 24th of April. — We have the Cowasjee Family, Duke 

 of Wellington and Eneas, nearly on a curved arc, of which the 

 chord lies from W. S. W. to the E. N. Eastward. Of these three 

 ships we find that the Cowasjee Family standing up to the N. West- 

 ward had the wind veering from N. E. at 4 a. m. ; to North at 10 



a. m. and Noon. It was also increasing in violence to " a perfect 

 hurricane" at 9 30 a. m., when, the ship lying to very badly, she very 

 properly bore up and scudded to the S. S. W. 



The next ship to the Cowasjee is the Wellington, at 43' to the N. E. 



b. N. of her, with a rapidly increasing gale at N. N. E., having had for 

 the preceding twenty-four hours some warnings from the sky, but the 

 Barometer having continued very high being at 30.00 at noon on the 

 23rd, and at 29.90 only on the 24th. The Nereid and Eneas the 

 next ships to the E. N. Eastward had still at noon on this day the 

 light baffling winds which so often precede a Cyclone. The Eneas 



* In former Memoirs (see Second Memoir, Journ. As. Soc. Vol. IX.) I have 

 found that Cyclones perfectly well traced and of moderate dimensions in the middle 

 of the Bay, and on the Coast of Coromandel, appear to commence near the Anda- 

 mans as large ones.
