1851.] A Twentieth Memoir on the Law of Storms. 201 



But there were evidently at this time (noon 26th) two Cyclones, 

 for we find that the Atalanta, 150 miles to the S. S. W. of the Neer- 

 landsch Indie, had at 11 a. m. of this day, "a sudden shift to the 

 Westward" with tremendous fury, carrying away the three topmasts, 

 mainmast head, &c. Now, this ship had been running down to the 

 S. S. W. with the wind gradually increasing and veering from E. N. 

 E. at p. m. of the 25th, till this time, so that it would appear that 

 this may have been at first a part of the original Cyclone wind, but we 

 cannot say when the separation commenced. The Ardaseer, 140 miles 

 to the Westward of the Atalanta, had but a strong N. W. b. W. 

 breeze with gloomy weather and heavy swells from the Eastward and 

 S. Eastward, and the Iskunder Shah at 150 miles to the N. b. W. of 

 her had as already noted, only threatening appearances up to midnight. 

 La Meuse also before noted, which ship was only 47 miles East of 

 the Iskunder Shah, had evidently part of the original Cyclone, for she 

 had the wind from N. E. to N. N. E. : at noon and p.. m. at North 

 veering rapidly to N. N. W. and blowing a hurricane at 7 p. m., and 

 gradually veering to West at 5 a. m. of the 27th when it reached to the 

 meridian of her position at that time. It would then appear that the 

 North West wind of the South Western quadrant of the main Cyclone, 

 and the S. Easterly wind of the N. East quadrant of the Atalanta' s 

 Cyclone, must have neutralized or overlaid each other, so as to prevent 

 the main Cyclone's extending so far as the position of the Iskunder 

 Shah. The vicinity of the Coast also probably affected the Cyclones 

 in some degree, as it always appears to do. 



On the 27th April. — Taking first the Atalanta 1 s small Cyclone, we 

 find it on this day at about 7 a. m. dismasting in one furious burst 

 the Iskunder Shah, and continuing till midnight a severe hurricane, 

 before it began to break ; but it was not of any great extent, for by 

 noon on this day it was fine with the Ardaseer though only 60 miles 

 South of the position which Capt. Shire assigns to the Iskunder Shah. 



Returning now to the principal Cyclone, we find that the Krishna, 

 Joseph Manook, Tavoy and Beacon Light Vessel, had all on this day 

 from midnight, severe gales from East and E. S. E. to S. E. : S. S. E. 

 and S. S. W. moderating in the afternoon and evening according to 

 their positions, being all more or less from 100 to 110 miles to the 

 North Eastward and E. N. Eastward of False Point.
