1842.] A Sixth Memoir on the Law of Storms in India. 679 



Experienced a very severe gale commencing at N. W., and veering 

 round to the E., and then abating in violence. It blew so hard while 

 it lasted, that it brought us under a close reefed storm mizen try-sail, 

 being compelled to take in the storm main and mizen stay-sail. The 

 Barometer fell during the gale to 29.42 at 8. p.m. Shortly after which 

 the gale moderated, and the Barometer gradually rose to 29.69. At 

 noon on the 13th October, Thermometer 84°. 



The Lowther Castle's storm, though apparently of small extent 

 and of short duration, is a very remarkable one, both for the fall 

 of the Barometer and the peculiar veering of the wind from N. W. 

 to East, which, with allowance for drift, will give a track of about 

 from N. 12° E. to the S. 12° W., which is much nearer the meridian 

 than any we have yet found coming from the N. E. The memoran- 

 dum is scanty enough, but I have thought it proper, on account of 

 its probably peculiar nature, to mark a conjectural track for it, as 

 serving to warn the seaman at this season of the year, that such small 

 storms may arise. It seems certain enough, that we have rotatory 

 storms of all sizes, and the only question in my mind is, If the very 

 small ones obey the same laws as the large ones, at sea and on 

 shore ? or if not, where the difference begins ? what is the law 

 for the smaller ones ? and what the cause of the difference ? These 

 questions I propose to investigate on a future day, and to do more than 

 to advert to them here, would be somewhat foreign to our present 

 subject.*

The Trough ton's Tyfoon, July 1835. 



Two severe Tyfoons occurred in the China seas in this year, during 

 the height of the N. W. Monsoon, being those of the Troughton and 

 the well-known one of the Raleigh ; as the first occurring, I give that 

 of the Troughton. 



* As an analogous instance of a small storm of great violence, but in travelling 

 about/rom SbE. to NbW. see Second Memoir on the Law of Storms, Jour. As. Soc,
