40G A Twenty-fourth Memoir on the Law of Storms. [No. 5. 



Eastward. Vivid lightning to the Northward and Southward. Wind 

 light from Northward and Westward. Swell rather decreasing. Ship 

 pitching very heavily, occasionally a few stars visible. Steering N. E. 

 by N. got a glimpse of the planet Venus, which gave us a Longitude 

 86° 30'. This worked back to Noon, gives a set to the Eastward of 65 

 miles from the previous Noon ! 



9 p. m. Bar. 29.70 ; Symp. 29.54; Aneroid 29.64; Ther. 85°. A tre- 

 mendous squall struck us from the N. W. with heavy rain. It veered to 

 West and S. W. blowing very hard, lightning very vivid, and sky all round 

 as black as ink. Thinking it possible that this might be the first breeze of 

 a Cyclone, I put the ships head to the Southward and reduced speed to 

 about 6 knots.* Observed a small meteor playing about the main top-gal- 

 lant mast head which disappeared in a few minutes. 



10 p. m. Bar. 29.70 ; Symp. 29.54; Aneroid 29.64; Ther. 85°. Dark 

 threatening appearance. Wind moderating at S. W. Midnight very vivid 

 lightning to the Southward with black threatening appearance. Wind 

 from S. W. and S. S. W. blowing a fresh gale at times with rain. 

 Barometers, &c. pretty stationary, still steering South and going slow. 



\hth May— a. m. Bar. 29.70; Symp. 29.60; Aneroid 29.63; Ther. 

 84°. Dark angry appearance all round. Strong S. S. Westerly wind 

 with rain, much less sea and swell, lightning less vivid. Put the ship's 

 head round to N. Eastward again, going quite slow. 



6 a. m. Bar. 29.71 ; Symp. 29.63 ; Aneroid 29.65 ; Ther. 85°. Gloomy 

 looking weather with moderate S. Westerly breeze. Swell moderate from 

 S. Eastward. Weather appearing more settled. Went on full speed for 

 the Pilot's Eidge Station. 



8, Bar. 29.68 ; Symp. 29.61 ; Aneroid .29 ; Ther. 84°. Noon Bar. 29.75 ; 

 Symp. 29.62 ; Ther. 86°. Lat. 19° 31' N, j Long. 87° 10' ; Pilot's Eidge 

 Station N. 12° E. 84'. 



American Ship Angelo. 



This ship was on the 12th May, in Lat. 13° 37' North ; Long. 82 d 

 3' East, and on the 15th, in 18 d 39' North ; Long. 86° 2' East with 

 variable winds from W. to S. East and S. W. a long heavy S. W. 

 swell all day, is the only remark on the 15th, and this continues on 

 the 16th. The Captain observed very threatening appearances . to 

 the N. East on the 14th, when in Lat. 17° 12' North ; 84° ltf 

 East; (Bar. fallen to 29.65 from 29.80 on the 13th,) but the sick- 

 ness on board prevented him from making notes.
