PROCEEDINGS OE THE GEOLOGICAL SOCIETY. [vol. lxxii, 



Vertebrata of the Fayum (Egypt), published by the Trustees of 

 the British Museum in 1906, began a new era in the history of 

 mammalian life. Your demonstration of the stages in the evolution 

 of the Proboscidea, and of the relationship between the Proboscidea 

 and the Sirenia ; your description and interpretation of the strange 

 Eocene genus Arsinoitherium ; and your recognition of the early 

 differentiation of the Hyracoids in Africa are especially funda- 

 mental contributions to biological and geological science. I would 

 further add that all your writings are characterized by remarkable 

 thoroughness and insight into the meaning of the facts described. 



As your colleague in the British Museum during the whole 

 period of your service, it gives me great pleasure to hand to you 

 this medal, which the Council of the Geological Society could not 

 have more worthily bestowed. 



Dr. Andrews replied in the following words : — 

 Mr. President, — 



I wish to express my most sincere thanks to the Council of the 

 Geologieal Society for the honour that it has done me in awarding 

 to me the Lyell Medal, and to you, Sir, for the too nattering terms 

 in which you have made the presentation. I am particularly 

 pleased to have received this medal from the hands of one with 

 whom I have been associated for so many years. You will 

 remember that, exactly twenty years ago, you yourself received 

 this award from Dr. Henry Woodward, and that at the same 

 time I received a moiety of the Balance of the Proceeds of the 

 Lyell Geological Fund. 



If I have been able to accomplish something in Vertebrate 

 Palaeontology, it is mainly due to the fortunate environment in 

 which I have found myself. An assistant in the British Museum 

 possesses quite exceptional advantages, having free access to the 

 great libraries and to the ever-increasing collections, and lastly, 

 but by no means least, having many opportunities of making the 

 personal acquaintance of workers interested in his subject. Having 

 enjoyed these privileges, I feel that I have somewhat fallen short 

 of what I ought to have accomplished ; but, although it is just 

 now uncertain what the future may have in store for us, I hope 

 that I may still have opportunities of doing further work such as 

 will justify this award.
