The rain of the 4th hist, having put a conclusion to a fine season of some 

 weeks' continuance, I availed myself of the opportunity of a journey made 

 immediately after it, to ascertain, as far as I could, its extent. 1 found that 

 it had rained from morning to night on that day all the way between London 

 and York, also (by information from other travellers) as far north a-, the 

 Tyne, and over the narrow part of the Maud, from Cheshire to Northumber- 

 land. It having been likewise a very wet clay on the south coast, I conclude 

 that probably the whole of England was, on this occasion, irrigated at once 

 from an Atlantic current, which during the prevalence of the easterly breeze 

 ju?t bef«re, hail taken possession of the higher atuiosphere, and which on that 

 day arrived, in its progress of subsidence, near enough to the earth to part 

 with its electricity, and displace the lower stream of air.
