20 A Twentieth Memoir on the Law of Storms. [No. 8. 



Tuesday, 23rd April. — a. m. light breeze and hazy weather, to Noon moderate 

 breeze at E. N. E. and hazy weather. Lat. Obs. 15° 18'; Long. 89° 26'; 

 Bar. 30.00 7 ; Simp. 29.75'; Ther. 86°. p. m. light breezes and cloudy weather, 

 wind E. N. E. to N. E. sky at sunset similar to the previous evening. 



%4th April. — a. m. fresh breezes and squally at times, wind N. E. Noon 

 strong breezes and continued rain ; double reefed the topsails ; breeze increas- 

 ing fast. Lat. by Acct. 13° 8'; Long. 88° 49'; Bar. 29.90; Simp. 29.60; 

 Ther. 83o, wind N. N. E. At 1 p. m. gale increasing fast with a close 

 threatening sky and continued rain. Bar. 29.85; Simp. 29.56; Ther. 83°. 

 Securing for bad weather, I judged now that we were in the left hand semi- 

 circle of a Cyclone coming from the S. Eastward, the centre bearing from 

 us E. by S. to E. S. E. and that a S. W. by S. course was the best to be 

 adopted, determined to carry all possible sail so as to run across the track of 

 the storm before the centre could overtake us. At 4 p. m. the gale increasing, 

 close reefed the fore and main topsails and furled the mizen topsail. Bar. 

 29.80; Simp. 29.50; Ther. 83°; heavy squalls at times with incessant rain 

 with a heavy sea from E. S. Eastward, wind at North. 6 p. m. wind inclining 

 to Westward of North. Bar. 29.76 ; Simp. 29.46 ; Ther. 84<>. At 8 p. m. 

 gale still increasing; Bar. 29.80; Simp. 29.50; Ther. 84°. At 10 p. m. 

 strong gale with hard squalls, assuming a very threatening appearance, heavy 

 Northerly sea with a deep cross sea from E. S. Eastward, Bar. 29.79; Simp. 

 29.47; Ther. 84°. Midnight wind from N. W. to N. W. by N. blowing a heavy 

 gale and the squalls still harder with continued rain (had several flashes of light- 

 ning from 10 P. m. to Midnight, to E. S. Eastward) Bar. 29.78 ; Simp. 29.43 ; 

 Ther. 84°. 



25th April.— At 1 a. m. squalls very severe with a tremendous sea ; took in the 

 fore and main topsails and scudded under the foresail and fore topmast staysail, 

 wind being now at N. W. At 2 a. m. it cleared up a little and became more moder- 

 ate. Bar. 29.72 ; Simp. 29.40 ; Ther. 84° ; the ship now scudding nicely under 

 foresail, wind being at N. W. by W. At 6 a. m. the weather moderating and 

 the sky looking much more settled, set the fore and main topsails. Bar. 29.78; 

 Ther. 84°, wind VV. by N. At 8 a. m. the weather continuing moderate made 

 sail. Bar. 29.90; Simp. 29.60; Ther. 84° ; the wind at West a North. At 

 Noon moderate breezes, the wind at West. Bar. 29.90 ; Simp. 29.60 ; Ther. 

 84°; Lat. by Obs. 10° 47' N. ; Long, by Chr. 86° 51' E. which gives 75 miles 

 current setting to N. W. by W. on the two last days' work, as calculated by 

 dead reckoning. A heavy sea following us from N. by W. At 5 p. m. passed 



jective colour from the effects of the red clouds ; but these accurate observations 

 are of high value as shewing the care of the observers.
