In one year the quantities were nearly alike in both places ; in the other years, the 
rain at Derry far exceeded that of Edinburgh. The quantity of rain that fell at 
Glasgow, on an average of thirty years, is marked at 29 inches in the same work.— 
Brewster’s Eneyclopedia. 
The average quantity of 51 inches, which Patterson attributed to England, is en- 
tirely too much.* Howard, in his work on the climate of London, states that the 
greatest quantity of rain during twenty-three years, fell in 1816 at London, and he 
gives the amotint as being 32 inches. He gives the general average for a period of 
twenty years at 25-179 inches, and the means taken on the ground.— Howard, Vol. 
IT. p. 185. 
Wakefield quotes Doctor Young, to show, that the average quantity of rain for 
England and Wales is 31 inches. 
The average quantity during eighteen years at Liverpool, which is not a very 
great distance from Kendal, was 34 inches.—Memoirs of the Lit. and Phil. Society 
of Manchester, Vol. LV. part 2, p. 575. 
Arthur Young observes—“ I have known gentlemen in Ireland deny their climate 
being moister than England ; but if they have eyes let them open them, and see the 
verdure that clothes theiy rocks, and compare it with ours in England, where the 
rocky soils are of a russet brown, however sweet the feed for the sheep.” 
In another place he remarks—* If as much rain fell upon the clays of England, as 
falls upon the rocks of her sister island, those lands could not be cultivated.’”— Tour 
in Ireland, Vol. 11. p. '74. 
The prevalence of winds which waft vapours to the island, is from an early date. 
The prevailing winds in the time of Camden, were the same in the time of Cam- 
brensis. Camden observes, that Giraldus said, not without reason=nature beheld the 
realm of zephyr, with an uncommonly favourable eye. 
Solinus described the Irish sea as being stormy‘‘ Mare quod Britanniam et Hi- 
berniam interluit, undosum et inquietum toto in anno, non nisi aestivis pauculis diebus 
est navigabile, navigant autem vimineis alveis quos circumdant ambitione tergorum 
bubulinorum— Solinus, c. 35. 
* Williams quotes Hales, who estimated the annual quantity of rain in England at 22 inches:i— 
Williams's Climate of Great Britain, p. 79.
