After thirty-two years' strenuous work in the Museum Dr. Arthur 

 Smith Woodward still retains the same untiring energy which has 

 impelled him since his earliest years to study hard and to travel. 

 Few scientific men can lay claim to so large a share of solid work 

 in his own special department or to have done more individually 

 to advance geology and palaeontology, the sciences to which he has 

 devoted his life. 



His principal separate publications are : — 



1899-1901. Catalogue of the Fossil Fishes in the British Museum (Natural 



History), pts. i-iv. 

 1890. [With Charles Davies Sheeboen.] A Catalogue of British Fossil 



Vertebrata. 

 1898. Outlines of Vertebrate Paleontology for Students of Zoology. 

 1902-12. The Fossil Fishes of the English Chalk. Monograph of the 



Palseontographical Society. 



He has also contributed 230 separate papers to scientific journals 

 and proceedings of various societies at home and abroad, including 

 upwards of fifty papers to the Geological Magazine.

MATERIALS for the study of this very distinctive genus have 

 been accumulating for many years, and at last afford a firm 

 basis for certain definite conclusions. Some important matters remain 

 obscure, and the comparison of the Swedish material has been 

 hindered by the dangerous state of the North Sea, but further delay
