468 MR MILNE ON TWO STORMS WHICH SWEPT OVER 



ferent parts of the United Kingdom, that the sinking of the barometer on the 25th 

 November took place every where, and was therefore produced by no merely local 

 cause, but by one which affected the entire mass of the atmosphere in this part 

 of the globe. This table shews the time when the barometer began to sink in 

 different parts of the United Kingdom ; and as the places are chronologically ar- 

 ranged, we can pretty nearly determine in what quarter the sinking commenced, 

 and in what direction the tendency to sink was propagated. 



At Adare Abbey* (near Limerick) Barometer began to sink on 25th Nov. between 1 a. m. and 9 a. m. 



... Aberavon (near Bristol) 9 a. m. and 10 p. m. 



... Farnborough (near Brgshot)t 10 a. m. and 11 p. m. 



... London (Somerset House) 9 a. m. and 3 p. m. 



... Greenwich Observatory 3 p. j,. and 9 a. m. on 26th. 



...Liverpool noon and noon on 26th. 



... Sunderland 9 a. m. and 9 a. m. on 26th. 



... Abbey St Bathan's (Berwickshire) 10 a. m. and 3 p. m. 



... Castle Toward (Firth of Clyde) 9 a. m. and 6 p. m. 



... Edinburgh Observatory about 5 p. m. 



... Inchkeith, Bell Rock, Pladda ") 



9 A. M. and 9 p. m, 



} 



Mull of Kintyre, Isle of Man 



... Cameron House (Loch Lomond) 10 a.m. and 10 p.m. 



... Kingussie (Inverness-shire) about 7 p. m. 



... Kinfauns (Perthshire) 84 p. m. and 94 a. m. on 26th. 



... Kinnaird Head (Aberdeenshire) 9 p. m. and 9 a. m. on 26th. 



... Inverness 8i p. m. and 9i a. m. on 26th. 



This table, so far as it goes, shews that the sinking of the barometer, and conse- 

 quently the change in our atmosphere which produced that sinking, commenced 

 in the south, and that it was propagated towards the north or north-east at the 

 rate of from twelve to sixteen miles an hour. 



Thus it appears that, in Scotland, on the evening of the 25th, the barometer 

 began to sink ; and I may now add, that it continued to sink, except for a short 

 interval to be afterwards mentioned, till the 29th, when it reached the lowest 

 depression. Its fall on the 25th and 26th was every where rapid ; but notwith- 

 standing this, there still prevailed in the lower atmospheric regions of Britain, 

 on the 26th, and even on the morning of the 27th November, an easterly wind 

 and severe frost, the well known concomitants of a high and rising barometer, — 

 shewing clearly that the upper regions of the atmosphere were in a very different 

 state, from those parts contiguous to the earth's surface. 



* This register is kept by Viscount Adarr. From the 25th to the 30th November, observations 

 were made on the barometer, thermometer, and direction of the wind, several times during each day, 

 and on the 28th every half hour. 



f The observations at Farnborough were made by the Honourable and Reverend Charles Harris 

 (a son of Lord Malmesbury). They were sent by him to Professor Forbes, accompanied by an ex- 

 tract from the Adare register, and Professor Forbes obligingly put them into my hands.
