VI TBEFACE. 



We are fortunate in possessing many of Mantell's 

 original specimens of Wealden plants, but, although his- 

 torically of great interest, they are largely superseded 

 by those recently obtained by Mr. P. Eufford, whose fine 

 collection has lately been acquired for the National 

 Museum. 



It is satisfactory to know that in this country the 

 long-neglected study of the Mesozoic plants is now being 

 taken up by so able a Botanist as Mr. Albert Seward, 

 and that the first instalment of his Catalogue is now 

 complete. 



It is expected that the Wealden plants will occupy two 

 fasciculi, and that the Oolitic plants of Yorkshire, of 

 which the Museum possesses exceptionally fine materials 

 obtained by the late Mr. Bean, by Dr. Murray of 

 Scarborough, and other well-known collectors, may be 

 similarly treated by Mr. Seward.
