398 A Twenty -four tli Memoir on the Law of Storms. [No. 5. 



Barometer is irregular, as it rose a little from midnight to 5 a. m., 

 when it should have been falling, and has been falling ever since, 

 when it should have been rising. We may therefore consider the 

 weather as somewhat suspicious, but the Sea continues remarkably 

 smooth and the surf is moderate ; however for the purpose of induc- 

 ing all due care and precaution I have made the signal — ' "Weather 

 is suspicious.' " 



Ship Eneas, Capt. Wright, from the Mauritius to Calcutta. 



Wednesday, \\ih May, 1852.— Lat. 9° 28' North; Long. 84o 4' East; 

 Bar.* 29.89; Symp. 28.80; Aneroid 29.74; Ther. 85°. Wind shifted 

 from S. W., thick squally weather, to W, b. N. ; fresh breeze and cloudy 

 to the Westward over the land ; at night much lightning, not so much 

 during the day, overcast appearance passing fast to the Northward. 



\2th.— Lat. 12o 39' N.; Long. 84° 40' E.; Bar. 29.85; Symp. 29.80; 

 Aneroid 29.75 ; Ther. 8/°. Wind between West and N. W. W. fresh 

 breeze with a peculiar white overcast appearance, but fine ; sun and stars 

 visible at intervals. 



13^.— Lat. 15° 38' N. ; Long. 85° 42' East; Bar. 29.75 ; Symp. 29.72 ; 

 Aneroid 29.65 : Ther. 87°. Wind variable between W. b. S. aud W. N. W. 

 overcast, sun obscured, swell Westerly,f much lightning all round, parti- 

 cularly to S. E. Easterly, and a thick squally appearance in that direction 

 which passed to North, several stars seen during the night. 



\Uh.— Lat. 17° 49' North; Long. 87° 5' East ; Bar. a. m. 29.62; r. m. 

 29.55 ; Symp. 29.66 ; p. m. 29.55 ; Aneroid a. m. 29 55 ; p. m. 29.45 ; Ther. 

 85°. These observations were taken at 10 a. m. and 10 p. m. ; at 9 p. m. 

 felt a short sea from N. Eastward for the first time, scarcely perceptible ; 

 the upper dense clouds appeared to move very slow to North or N. b. W. 

 the lower clouds with the wind ; stood on our course till lh. a. m. 



\5th. — Sea increasing very fast, ship running at nine miles per hour 

 overcast appearance more dense and black, stars seen at intervals, wind 

 between W. b. N. to N. W. variable. Judging from the whole being so 

 steady between W. b. N. and N. W. all the way up from Ceylon, more 

 from W. N. W. than N. W. that the Cyclone was making a Northerly 

 course and my Bar. not being very low, that it was some distance from me, 

 I stood to East Southerly about sixty miles. At 1 a. m. on the 15th, sea 

 increasing very much ; during this time much lightning all round, com- 



* Observations made at 10 a. m.
