So that the rain in this part of Cornwall exceeded that at Carlisle almost half 

 an inch. 



It is some amusement to compare the journal of the weather in one part with 

 the accounts in the papers of storms, heats, and drought, and their contraries, 

 in another. On the 1 1th of August, there was at Brussels a most dreadful storm 

 of thunder, lightning, and hail: at Ludgvan only misty rain and showers. On 

 the 19th of the same month, when one of the most violent hurricanes ever known 

 scourged some parts of Kent, from the w. and s.w., it was calm, hazy, and sun- 

 shine, and the wind at n.e. in Mount's Bay, in the morning; in the evening 

 s.s.E. On the 2d of this month of October, there was a most violent storm on 

 the eastern coasts of Britain, from Yarmouth to Edinburgh; wind from the n.e. 

 andE.N.E.; many ships distressed, many wrecked. What is remarkable, at the 

 same time a like violent storm blew in the western channel, along the coasts of 

 Cumberland, Lancashire, and Wales, but the wind from the west. In Mount's 

 bay the wind was somewhat stormy and showery in the morning, the wind at 

 west half north; in the afternoon windy and showery and sun-shine, west half 

 south. Thus we see how different, nay opposite, the winds, even in their ex- 

 tremest violence, are on the eastern and western coasts, where they have nothing 

 between them but a narrow ridge of land. The cause of this remarkable oppo- 

 sition, Mr. B. would be glad to see well explained. It must certainly, he thinks, 

 have lain in the middle between the two forces; and it might contribute some- 

 what to the discovery, to know whence, and to what degree, the wind blew on 

 the mountains in Scotland, and as far south as Derbyshire, from Sunday morn- 

 ing to Monday noon.
