66 Eleventh Memoir on the Law of Storms in India. [No. 157. 



dering the reports from Madras and Ceylon, for the 1st and 2d to- 

 gether. 



First, in reference to the general effects of the storm on the Coast: 

 we shall observe on inspecting the chart, that there are at least two 

 storms on this day, the Mary Imrie, Niagara and Fyzulbarry's being 

 one, and the Candahar's another, travelling up on a N. Westerly 

 course more or less curving, apparently to the Westward, as 

 they approach each other,* and this bending by the way is a 

 very remarkable feature. The average distance of the centres of the 

 two storms from the coast we may call about 3J degrees. The Can- 

 dahar's storm we know to have been of very small extent (taking 

 her position on this day as correct) as it is determined by the Vernon's 

 which is certainly exact within the trifling distance arising from 

 the defects of all observations in bad weather. The Mary Imrie's 

 storm we have admitted to be the Niagara's on this day, and we shall 

 find that this projected will bring the circumference of her storm 

 to within two degrees of the North end of Ceylon, and that the joint 

 effect of both vorticse would be to create a Northerly, and N. West- 

 erly wind, stream, or gale if their influence extended so far; and they 

 ought moreover to create a Northerly and N. Easterly stream at 

 Madras. Now we know that at Madras which is as far to the N. W. 

 as Kay to and Paumbum are to the West, and W. S. W. of the centres 

 of the 1st and 2d, there were also the indications of an approaching 

 storm in the increasing surf and slight fall of the Bar.t as well as the 

 North current, (see remarks on Capt. Biden's report,) and that the 

 wind was from the North and North East on the 2d, and to 4 a. m. 

 on the 3rd, changing afterwards to S. E. From the effects of the ranges 

 of hills (and even mountains) between Madras and the north end of 

 Ceylon, it is impossible to go farther than to indicate generally what 

 the average effects of a storm would be, as every separate spur and 

 range would produce necessarily some local effect. On the coast we 

 have the effects of the storm current in the " North current," and we 

 have finally within these three days : 



* The Colonel Burney's storm may have been a third for anything we know, and 

 it may be to it, that the Logs of the Carena and Bittern relate. 



1 1 should consider this slight fall of the Bar. as some evidence in favor of the 

 relation of the two storms and their bending to the Westward which I have sup- 

 posed.
