wyn ; the former is much higher than Sketty, more exposed, and 

 four miles further inland, the latter is in nearly the same situation 

 as Sketty. 



From Singleton, near Swansea, Mr. Vivian states, that the 

 lowest degree of cold experienced in that neighbourhood was on 

 the morning of the 20th, when Fahrenheit's thermometer stood at 

 15° soon after day break. The depth of snow at no time exceeded 

 2 inches, and during the severest weather there was no snow on 

 the ground. 



Near Liverpool, the frost was much less intense than around 

 London ; Mr. Walker states, that, in the neighbourhood of that 

 town, gardens suffered far less than in places to the East and 

 South, especially in Yorkshire, Derbyshire and Nottinghamshire. 

 Calderstone, Mr. Walker's residence, is from 100 to 150 feet 

 above the sea ; the register thermometer did not fall below 9° on 

 the morning of the 20th, nor could he learn that it had been 

 lower in his vicinity. The greatest depth to which the frost pene- 

 trated the soil was found to have been from 12 to 18 inches, 

 accordingly as the ground was covered with grass or otherwise. 

 Very few of his extensive collection of evergreen trees and shrubs 

 were entirely destroyed. It was here, and elsewhere, remarked 

 that the double Ulex europaeus was more hardy than the wild 

 species, and that Ulex strictus, the Irish furze, suffered more than 

 either. 



In Ireland, as is usual, the winter was much less severe ; 

 Mr. Mackay reports the lowest temperature in Trinity College 

 Garden, Dublin, to have been only 20°. Mr. Robertson, in 

 the Gardener's Magazine, speaks of the cold of Kilkenny as having 

 also been 20°, at the distance of 40 miles from the sea, and at the 

 computed elevation of 500 feet. 



In the Glasnevin Botanic Garden, the thermometer is stated by 

 Mr. Niven not to have fallen below 15° above zero. In this station
