660 A Sixth Memoir on the Law of Storms in India. [No. 127. 



this disturbance preceded the tyfoon, not at least by so great an interval 

 of time as from ten to twelve hours.* 



Upon the whole, then, I should be inclined to suppose, that there 

 were two storms, of which the centre of that of the ships at sea, bore 

 North from the Charles Grant and Lady Melville, at 1 a. m. on 

 the 9th, and as it was not severe, and not felt at Lintin, it was pro- 

 bably of small extent. I have then marked a conjectural track for 

 it in No. XIV., from S. 78° E. to the N. 78° W., and those who 

 study the subject, will agree with, or dissent from my views as they 

 please. I have laid down the Lintin storm as coming from East, the 

 height of it appearing to have been about noon, when the centre would 

 have borne S. S. W. from the ships ; but this is almost conjectural, for 

 amongst high rocky islands like those at the entrance of Canton river, 

 the wind may have been modified in many ways. The storm of the 

 ships at sea I have laid down as passing from the E. S. E. to the 

 W. N. W., though from the absence of any registry of the Barometer, 

 except at noon, we cannot say when the storm fairly began or ended ; 

 but with due allowance for the run of the ships in the interim, 

 I think it may be taken as far to the Southward as this. 



The Waterloo's Storm. 



Document from the East India House — Mr. Packman. 



26th August, 1829. — The H. C. S. Waterloo appears also to have 

 been within the range of one of those E. S. Easterly storms, about a 

 degree farther to the Southward, than the ships in the former article. 

 The following is the memorandum sent me, but I have not marked a 

 conjectural track from it, as no other document has been obtained 

 relative to this storm, which indeed we could scarcely notice as one, 

 but for the remarkable fall of the Barometer. 



H. C. S. Waterloo, in the China Sea. 

 26th August, 1829. — A brisk monsoon in the first and middle parts 

 with squalls and rain, in the latter variable from the N. W., and 



* Even supposing the storm to have come from the N. E. still it cannot be recon- 

 ciled, as to distances from the centre and intensity, with the times, so that all things 

 considered, two separate storms is the most probable supposition.
