On the Fossil Flora of Alum Bay. 



231 



further investigations are completed. The most striking fact, how- 

 ever, in connexion with the Alum Bay Flora that my work even at 

 this stage has brought out, is, that more than fifty of the species are 

 common to Sotzka and Haering, while a lesser number are common to 

 Sezanne, the Lignitic of America, and to other Floras. 



It is my pleasing duty to have again to acknowledge my thanks 

 for the very important help the Royal Society has afforded me. I 

 have also to acknowledge my indebtedness for advice and assistance 

 to Sir Joseph Hooker, Dr. Henry Woodward, Mr. William Carruthers, 

 Mr. T. G. Baker, Mr. R. Etheridge, jun., Professor T. M. K. Hughes, 

 and Mr. J. S. Gardner.
