1845.] Eleventh Memoir of the Law of Storms in India. 67 



1st, 2d and 3rd Nov. — The Bar. first falling, then about stationary, 

 and lastly rising again to its former level as if it had just felt the 

 storm, but no more. The indications at Ceylon on the 2d are clear- 

 ly those of a storm passing over the South extremity of the Peninsula, 

 and probably, if we had any reports from Tranquebar or between it, 

 and point Calymere we shall find that there really was a shift there- 

 abouts, while the rapid veering at the station of Paumbum was taking 

 place. It is possible that the tendency of the whole aerial impulse, 

 like a storm or tide wave, was as usual, to force its way through the 

 Paulgatcherry pass, as shewn in my eighth Memoir. 



I must not conclude this part of the summary without noticing the 

 remarkable fact of the Mary Imrie's Bar. remaining so high, though 

 fluctuating greatly, in the first storm ; and in the second falling to 29° 

 25. It will be noticed and for the present I should suppose this is the 

 cause of this anomaly, that she was at the time her Bar. stood so high, 

 in the N. West quadrant (having the wind at N. N. E.) of her first 

 storm, and she had thus both the effect of the verge of the coming storm 

 which sometimes and perhaps always, raises the Bar.* and also that of 

 the monsoon from the N. Eastern part of the Bay. The Ariel's storm 

 in my sixth Memoir, Vol. p. 686 of Journal is another instance in which 

 this seems to have occurred with two storms coming up in different 

 directions and both at a considerable angle to the monsoon. We find 

 from the Vernon's log that it was blowing a fresh monsoon from the 

 N. N. E. on this day. The oscillation I have frequently remarked 

 upon, and if Capt. Boyd had had a Sympiesometer on board, no 

 doubt the warning would have been still more distinctly given. 



Extract from the Log of the Ship Emily, Captain Anderson from 

 Shields to Calcutta, reduced to Civil Time. 



The following log reached me after the chart was lithographed; 

 it will be seen by it that the Emily was skirting the Fyzulbarry's 

 storm to the Eastward on the 27th and 28th, as the Winifred was to 

 the Westward. From the heights of the Emily's Bar. we may infer 

 that she had really no part of the vortex but rather a heavy monsoon
