This inference was corroborated by tha periods at which, in dif- 

 ferent places, the wind in the stoiin veered from SE. to SW. This 

 veering, which took place in Cornwall ab(tut noon on 2Slh, did not 

 take place at Kirkaldy till the aflernoon of the 29//i. 



A separate and still more striking confirmation is afforded by 

 the period when the barometer reached its lowest point at different 

 places. Its greatest depression in the Bristol Channel occurred at 

 noon on the 28th ; in Edinburgh and Glasgow, at 12 h. 16 m. on the 

 29th ; in Kinfauns Castle (Perthshire), at 8^ P.M. on the 29th. 



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

 to N.NE., there can be no doubt; and from its moving in nearly 

 the same track, but travelling with twice the rapidity, it overtook 

 the first storm about the middle of Scotland ; in consequence of 

 which, the indications of two separate storms became indistinct in 

 these northern parts. 



There were many circumstances shewing that this second storm 

 had a rotatory as well as a progressive motion, and that the centre 

 of the stormy circle travelled along a path considerably to the west 

 of the British islands. (1.) One of these was the greater magni- 

 tude of the angle made by the wind in veering, and the greater 

 rapidity with which the veering was effected, in places situated 

 to the west, than in places situated to the east. At Limerick, the 

 wind veered 158" in 28| hours ; at Penzance, 112^ in 24 hours; 

 at Greenwich, 79^ in 24 hours ; at Kinfauns, 90^ in 24 hours. (2.) 

 When the storm ceased, the wind was blowing more from the 

 north in places situated to the west. On the west coast of Ireland, 

 it was blowing W. or VV.NW. ; in the south-west of Scotland, and 

 at Holyhead, it was blowing W.SW. or SW. (3.) The barome- 

 ter was lowest towards the west ; and by classing together those 

 places where the depression was the same, it appeared that these 

 places lay in lines or zones running in a N.NE. direction, in each 

 of which the barometer stood at a lower level in proportion as its 

 situation was toward the west. In London and Greenwich, the 

 barometer stood at its greatest depression at 28.70 ; at Lime- 

 rick, it stood at its greatest depression at 27.49, both observa- 

 tions being reduced for height. (4.) It was found that a storm 

 had traversed the eastern part of the Atlantic, moving in a N.NE. 

 direction, having been felt at the Garonne on the 27th, 28th, and 

 29th ; at Oporto, from the 24th to the 27th ; at Lisbon, on the 

 night of the 23d. It appeared that several vessels in the middle
