DICKS0N1A ANTARCTICA. 127 



I may here remark that there exists a very fine collection 

 of Ferns at Wentworth, under the able management of Mr. 

 Joseph Henderson, a gentleman who, for many years has made 

 this branch of Cryptogamic botany his favourite study, and who 

 is noted for his kindness to those who feel a desire to see the 

 collection, or who wish for information on any subject connected 

 with it. I myself am especially obligated for much valuable 

 information, as well as many plants and fronds: indeed, the 

 present work is largely indebted to Mr. Henderson, for the 

 kind assistance he has rendered from time to time. 



For a plant and fronds my thanks are due to Mr. Joseph 

 Henderson, of Wentworth. 



It may be procured from Messrs. Veitch, of Chelsea; Sim, 

 of Foot's Cray; Rollisson, of Tooting; E. G. Henderson, of 

 St. John's Wood; A. Henderson, of Pine-apple Place; Stansfield, 

 of Todmorden; Booth, of Hamburg; and Cooling, of Derby. 



The illustration is from Mr. Henderson's fronds.
