Observations upon the effects of Frost, 



was killed in the midland and northern counties, but not in 

 the southern ; at Dropmore, a plant growing against a south 

 wall, was found quite dead ; but Mr. Forbes reports from 

 Woburn, that his plant is only injured at the extremity of 

 the young shoots. In the Society's Garden, and at Owston, 

 this species would not have died had not the stock of Arbutus 

 Unedo, upon which it was grafted, been killed. 



Asparagus scandens was killed to the ground in the garden of 

 the Society, but pushed up again vigorously. 



Atriplex portulacoides, a British plant, was killed in the Society's 

 Garden. 



Buxus balearica was uninjured at Sketty, at Penllargare, at Owston, 

 and about London. 



Bumelia tenax was killed in the Society's Garden ; but not in- 

 jured at Abbotsbury. 



Bupleurum fruticosum was scarcely affected near London, and to 

 the south, but at Cambridge it was killed, and it is well 

 known to be a tender plant in the midland counties. At 

 Owston it was much injured. 



Cistuses were killed in almost all places, with the exception 

 of the gum cistus, which occasionally escaped; in the 

 Society's Garden the whole collection, among which were 

 many plants 8 or 10 years old, were destroyed. C. lauri- 

 folius was uninjured at Spolforth; at Singleton, Mr. Vivian 

 lost all but laurifolius and corboricnsis ; at Sketty, laurifolius 

 was the only species that remained entirely unhurt, and next 

 to that species corboriensis was least injured ; at Abbots- 

 bury C. salvifolius and purpureus perished, but C. villosus, 

 laurifolius, cyprius, and creticus were uninjured ; in Norfolk, 

 in Hampshire, in Kent, and the neighbouring counties, the 

 collections of this genus were almost annihilated. 



Celtis orientalis was killed on a south wall in the Society's 

 Garden, where it had lived many years.
