Xii LETTEK OF TRANSMITTAL. 



Coast Survey, for the Smithsonian Institution. The specimens were sent 

 to me for determination, and I was allowed to give in volume VIII a short 

 description of the new species added to the Alaskan Flora already partly 

 known by the works of Heer. These new species have been figured in 

 the Proceedings of the National Museum, vol. v, pi. vi-x. 



It is not unnecessary to remark that all the plants described in vol- 

 ume VIII are considered in separate groups according to their relation to 

 the age of the formation which they determine. Comparisons are estab- 

 lished with the European Floras by tables of distribution, etc. 



I truly believe that this volume will prove to be a very valuable con- 

 tribution, not merely to the paleontology but also to the geology of this 

 country. 



Very truly and respectfully yours, 



LEO LESQUEREUX.
