1842.] A Sixth Memoir on the Law of Storms in India. 715 



now proceed to shew how far we have, as it appears to me, done 

 this. 



I should state here, that I have as carefully looked for contradictions 

 as for confirmations of the usual law, and for tracks of storms from the 

 Westward as well as from the Eastward ; but in no instance have I been 

 able to find data which would admit of this supposition, while all are, 

 as it seems to me, easily and simply accounted for by assuming the 

 rotation from left to right in the Northern hemisphere and tracks 

 from some point to the Eastward of the meridian. Of the progression 

 again, though we have not in the confined space and track which the 

 China Sea affords, such direct evidence of it as we have in the Bay of 

 Bengal, yet we have some, as in the case of the Magicienne and St. 

 Paul, and the Raleigh which are direct enough, and we have again 

 and again, which is perhaps of more importance, the increasing 

 strength, varying direction, sudden changes, contrary shifts, and de- 

 creasing violence of the storms, which are exactly what should occur 

 with a progressive whirlwind. The Raleigh's storm, so ably ana- 

 lysed by Mr. Redfield, and the Manilla and Panama's first storm are 

 clear instances of well-ascertained progression, and the use of the 

 hurricane card will shew that in every instance in which the direct 

 evidence of ships in different positions is wanting, the indirect evidence 

 which this demonstration furnishes, is almost equal to it, for it can be 

 accounted for in no other way. 



A third kind of proof may be deduced from those cases, (as that of 

 the Elphinstone,) in which vessels, by bearing up, have evidently 

 chased and ran into the more violent parts of their storms again, while 

 others by lying to a little longer, have allowed it to leave them. 



A fourth kind of proof is also worthy of notice. It will be seen by 

 the log of the Glatton, p. 644, which ship was on the southern verge of 

 H. M. S. Theban's Storm Track, No. VII., and was standing on, so as 

 to cross the wake of it a few hours after the Theban and other vessels 

 had been dismasted, that she crossed the ''confused sea" which the 

 passage of the vortex had left. This is always described as creating 

 the awful " pyramidal" sea, a state of the elements of which no man 

 who has not witnessed it can form any conception, and no doubt this 

 confused sea is the remains of it. The same occurred, and most re- 

 markably, to the London Thetis, as described in Captain Cass' very
