Award or the Lyell Medal. 



The President then presented the Lyell Medal to Dr. Arthur 

 Vaughan, B.A., addressing him in the following words : — 



Dr. Vaughan, — 



The lyell Medal is awarded to yon in recognition of yonr distin- 

 guished services to Geology, especially in establishing the order of 

 the Faunal Succession in the Lower Carboniferous rocks of Britain. 



In your earlier studies of the Jurassic zones with their teeming 

 fossils, you acquired a mastery over the investigation of the known 

 which enabled you to venture with confidence into unexplored 

 regions. Thanks to your researches, the Avon Gorge, once famous 

 for its beauty, has now become no less famous as a scale of geological 

 time. 



From all sides — Wales, Ireland, France, Belgium, Germany, and 

 remote parts of Britain — geologists, attracted by this long-desired 

 means of correlation, have hastened on pilgrimage to Clifton, where, 

 under your illuminating teaching, they have been made familiar 

 in all its details with the new standard of reference. 



How fortunate have been the results the pages of our Journal bear 

 witness ; our kuowlcdge of the stratified crust has been enriched 

 by a whole chapter, and the method of William Smith has once 

 more achieved a triumph. 



Of your power to instruct I speak with experience, for I was your 

 pupil when last I visited the Avon section ; this recollection adds 

 to the pleasure with which, in the name of the Council, I hand you 

 this award. 



Dr. Vaughan replied as follows : — 

 Mr. President, — 



Nothing could have given me greater delight, or have come at 

 a more opportune moment, than the news of the award to me of 

 the Lyell Medal. 



With the zest for fresh labours partly dulled by a long illness, 

 this eagerly desired prize came as a welcome spur, restoring self- 

 confidence by assuring me of the sympathy of brother geologists. 

 As yet, Sir, I can only hope that, some day, I may have done more 

 to deserve this great honour and the kind words with which you 

 have so generously accompanied its bestowal. 



My thanks are rendered heartily and, in very truth, humbly to
