blew from SR. or SSE. ; it afterwards veered to SW., and on the 

 cessation of the storm it was blowing- from NW. The veering to 

 SW. took place in Cornwall dnring the forenoon of the 27th ; it 

 took place in Dublin in the evening of that day. 



Heavy gusts came from a point due west, or rather to the north 

 of west, shortly before the cessation of the storm. Tliese were 

 felt in Cornwall in tlie afternoon of the 27lh ; they did not com- 

 mence at Pladda (off the coast of Ayrshire) till tiie night of the 

 2&h November. 



Fi'om those and otiier similar data, it v>as concluded, tliat the 

 storm moved progressively in a N.NE. direction, at the rate of 

 ten or eleven miles an hour. 



The progress of this storm from southern latitudes was next de- 

 scribed, by reference to various places both on sea and land, as far 

 south as Gibraltar, at all of wliich it bad been severely felt. On 

 the 22d and 23d, a storm from the S. was experienced at tlie 

 mouth of the Garonne. Off tiie N\V^ coast of Portugal, three ves- 

 sels were dismasted by a hurricane on the 22d ; at Gibraltar, thert; 

 was a storm on the 21st November. It was most probably one 

 and the same storm wliich passed over all these places, beginning 

 at Gibraltar on the 21st, and reaching tl-.o British islands on t!ie 

 26th November ; — seeing it would ariive tiiere at the very time 

 'hat the first storm begun in England, and had the same direction 

 and rate of movement. 



Some circumstances were stated, shev.ing that this storm had 

 probably a rotatory as well as a progressive motion. These were, 

 ( 1.) the great velocity of the wind in the storm, compared with the 

 .•'.ctual motion of the storm ; (2.) the veering of tlie wind in the 

 ."torm from SE. to N VV. ; (3.) the greater violence <if the gusts 

 from S. and SW., — the piogressive and rotatory motions then 

 coincided. 



II. The second storm begun on the SW. coast of Ireland about 

 •-' A. M. on the 2Sth ; at Cork, about 3 or 4 a. si. ; Cornwall, about 

 .") A. M. ; Plymouth, about 9 A.m.; and Fairnborougli (near L5ag- 

 s!iot), about 10 A. M. 



At all tliese places there was, during the previous night, a calm, 

 oi' light jiirs from the westward. 



This storm reached Dul)lin about 1 r. .m. on the 28th ; Glasgow, 

 about 3 P. M ; and Kirkaldy, between 4 and 6 p.m. It travelled 

 northward, tlierefore, at tiie rate of about twenty miles an hour. 



This inference was corroborated by tha periods r.t whicli, in dif- 

 r> rent places, the wind in the storm veered from SE. to S\A\ This 

 veering, which took place in Cornwall about noon on '2Sth, did not 

 toke place at Kirkaldy till the afternoon of the 29//^. 



A separate and still more striking confirmation is afforded by 

 i'ie period when the barometer reached its lowest point at different 

 p! ices. Its greatest depression in the Bristol Cliannel occurred at 

 lioon on the 28th ; in Edinburgh and Glasgow, at 12 h. IGm. on the 

 2';th ; in Kinfauns Castle (Perthshire), at 8^ p.m. on the 29th. 



That this storm had, like the previous one, a progressive motion
