of this Society on the 17th of February), the author quoted some 

 remarks from Captain Beechey's Journal, with regard to the frequent 

 occurrence of a luxuriant vegetation under the snow in the Arctic 

 regions. He more particularly adduced the instance of Saxift'aga 

 nivalis, stated by Linnaeus to flower in the regions of perpetual snow. 

 The author also offered some remarks on the modifications which the 

 specific characters of both plants and insects undergo, when exposed 

 to the influence of a change of climate. 



Dr. Hooker mentioned that when at Tierra del Fuego he had seen 

 Pernettya mucronata flowering in a spot from which the snow had 

 been accidentally removed. 



Mr. Pratt stated that at Chaumouni he had sought for plants in 

 flower under the snow, but without success ; and he looked upon the 

 circumstance mentioned by Mr. Curtis as an accidental occurrence. 



Read also a communication from Mr. J. Mottley, of Labuan, which 

 was accompanied by specimens of Borneo camphor, and of the tree 

 {Dryobalanoios Caniphora) by which it was produced. This camphor 

 is consumed chiefly in China, where it is greatly valued for its medi- 

 cinal qualities. The best specimens realize £b per pound. The oil 

 exuding from the tree is also used in medicine and as a varnish. With 

 the Borneo camphor are invariably mixed the red seeds of a plant, 

 which are added by the natives under the superstitious idea that the 

 Spirit of the camphor would fly off, unless some such inducement were 

 offered him to remain.

Introduction. 



Physical Geography and Botanical Divisions of the County. 



The county of Surrey is situated in the south-eastern part of Eng- 

 land. It is an inland county, bordered on the north by the river 

 Thames, which separates it from Middlesex and Buckinghamshire ; 

 on the east it is bounded by Kent ; on the south, by Sussex ; and on 

 the west, by Hampshire and Berkshire. 



The form or outline of the county is nearly that of an oblong quad- 

 rangle, deeply indented, however, on the north side by the winding 

 current of the Thames, and more slightly on the west, where a branch
