2/8 Seventeenth Memoir on the Law of Storms. [March, 



shifts experienced by the first division, remembering that they were in 



different parts of the central calm space, from 1 5 to 20 miles or more in 



diameter, since the calm lasted about two hours. 



We have then the different ships as follows, viz. 



Wind at f Shifted at about 2"j Shewing a 



Noon J p. m. after a lull I track to the 

 Ship Cuffnells, N. E. ] to W. b. N. veering f W. b. N. 



L rapidly to S. S. E.J 



Buccleugh, North S. W. W. N. W. 



Taunton Castle, N. N. E. S. S. W. W. N. W. 



which will give a track of about N. 71° 15' West, but as we find that 

 the wind veered with the second division but slowly to the E. S. E. and 

 S. E. we may allow the track to have been a little more to the North- 

 ward, and I estimate it to have been really about N. 65° W. 



In the Log of the Buccleugh occurs a remarkable notice of the 

 curious phenomenon, the red sky, which is evidently here, as in the 

 China Sea and in the Southern Indian Ocean, a precursory sign of the 

 Cyclones.* The passage occurs in Mr. Lynn's notes, as follows : — 



" At sunset the clouds predicted another severe tyfoon ; the appearance was 

 that of remarkably large and dense clouds surrounding the horizon at an altitude 

 of about 10 to 15 degrees, having their edges tinged with a deep crimson border, 

 or if bound with a ribbon of that colour, and reflecting an awful redness on the 

 sails, which appearance had also preceded the former gales, and which I shall 

 ever conceive are certain indications of their approach ; made every thing as snug 

 as possible before night." 



Track X. 



The Buccleugh experienced a fourth Tyfoon, from the 1 6th to the 

 18th of July, which is entered as follows in Mr. Lynn's remarks : — 



"On the 16th at Noon the Cuffnells made signal that the Bar. was again 

 falling ; immediately prepared for another tyfoon, which commencing in the N. N. 

 E. and veering in the same way exactly as the former ones to North N. N. W., 

 N. W. and West, from thence to W. S., W. S. W. and South, when after two 

 days' continuance of severe blowing it moderated. And we then observed in Lat. 

 17° 1G' North ; Long. 128° 14' East." 



* While writing this I learn also that it is so too for the Bay of Bengal, and more- 

 over, that it has occurred in two instances (Cyclone of October 1848, with the ship 

 Ear ham, and Cylone of Oct. 1832 with the ship Albion) at night by moonlight !
