1851.] A Twentieth Memoir on the Law of Storms. 21 



the ship " Cowasjee Family" standing to the N. Westward, he communicated 

 to us by signals that he had experienced much bad weather. 



26th April.— a. m. moderate breezes at S. W. by W. and cloudy weather, 

 at Noon, ditto winds and clear weather the ship tumbling about with a heavy sea 

 from the Northward. Lat. Obs. 8° 56' ; Long, by Chr. 87° 34' ; Bar. 29.97 ; 

 Simp. 29.70; Ther. 85°. From hence we stood to the S. Eastward with 

 light breezes from S. Westward. 



Our position at Noon of the 24th was, by Acct. from the day previous, Lat. 

 13o 8' N. ; Long. 88° 49' E. But as we found we had been set to the West- 

 ward 60 miles at least, during the 24th and 25th (by the Noon Obs. of the latter 

 day), I allow 20 miles set to the West during the 24th, as during the greater 

 part of this day the weather was fine. Our position therefore on the 24th a t 

 noon would be Lat. 13° 8' N. ; Long. 88° 29' E. ; with the wind N. N. E. and 

 close continued rain — this would give the centre of the storm E. S. E. distant 

 say 150 miles: viz. the centre of its position would be Lat. 12° 14' N. ; Long. 

 90° 52' E. From Noon until 8 p. m. we ran S. W. by S. 60 miles, and from 

 8 p. m. to Midnight 35 miles, with a strong set to N. W. by W. I allow the 

 course made good to be S. W. \ S. 95 miles, from Noon until Midnight; the 

 wind was then N. W. making the centre to bear from us N. E. and somewhat 

 nearer than at Noon, as the wind had considerably increased and the squalls had 

 become much more severe ; say distant from us 120 to 130 miles. The centre 

 of the storm would now be in Lat. 13° 27'; Long. 89° 3' (only 37 miles to 

 the North East of the ship's position at Noon) — and it would have travelled N. 

 54° W. at the rate of 11 miles per hour; coming from the North end of the 

 Little Andaman in a direct line to Vizagapatam. 



At 1 a. m. the centre of the storm would be in its nearest approach to us as 

 the bearing of the centre from the ship's position then, formed a right angle 

 with the track on which the storm was travelling, in confirmation of which the 

 glasses were then at their lowest point and the squalls so severe, that I took the 

 topsails in, fearing the yards might give way. And I felt satisfied that the storm 

 was travelling to the North-westward, and was then at its nearest approach to 

 us, and that every mile it travelled and every mile we sailed was increasing the 

 distance between us, which proved to be correct; for by 2 a. m. the weather 

 cleared considerably and was more moderate. I had not left the deck from 

 Noon until this time, except when going down to note the glasses. I put a sheet 

 of paper and pencil in a convenient place at Noon, when I judged we had o-ot 

 into a Cyclone, so that what I have stated was noted by myself and when 

 observed ; the appearance of the sky I could not make much note of as we 

 had almost continued rain until towards midnight when it would clear a little. 

 Between the squalls the sky at that time assumed a very threatening appearance ;
