VI PREFACE. 



Brongniart, Lindley, Hutton, Saporta, and other Paleeo- 

 botanists of note, and it is very gratifying to find that so 

 accomplished a botanist as Mr. A. 0. Seward has now 

 undertaken to Catalogue the Collection in the Geological 

 Department which has remained for so long a time without 

 a historian.
