880 Fourteenth Memoir on the Law of Storms in India. [No. 168. 



Ship Caledonia, Captain Burn. 



I have fortunately two abstracts of this ship's Log : fortunately, 

 because in the one there is evidently some grave oversight as to the ship's 

 place, which on the 29th, is made 49', and on the 30th, when she was 

 becalmed at the centre of the hurricane, 68' miles ! to the Eastward of 

 the one now printed ; which being in Capt. Burn's hand writing, I take 

 to be the correct one. It has also the advantage of having the barome- 

 trical observations. 



Extract from Ship Caledonia's Log Book; Bay of Bengal. Reduced to 

 civil time. Forwarded by the Chamber of Commerce, Bombay. 



Saturday, 29M November, 1845. — Throughout a moderate breeze, from 

 Southward and SE. with passing squalls, and constant rain. Latitude 

 by account 6° 50' North, longitude 88° 30' East ; barometer 29.70 ; ship 

 under double-reefed top -sails, and reefed courses, as the weather looked 

 threatening. The two previous days we had much rain, and vivid 

 lightning from the Northward and NW., and a heavy swell the last day 

 from SW. 



From noon till midnight, a fresh breeze from South and SSE., with 

 heavy rain at times, swell increasing. Barometer 29.70. Distance run 

 from noon to midnight ninety miles. Course West.

meter 29.50.

South to SE., and back again ; a very heavy swell from 

 SW. Barometer 29.50. 

 „ 7 a. m. Wind suddenly shifted to East, and increased to a 



very heavy gale, which obliged us to cut away the sails 

 we had set, and lay the ship to, with her head to the 

 Southward. Barometer 29.50. 

 8-30 a. m. Gale at its height. Barometer 29.50.

 len to 29.40.
