subdivisions of the Devonian strata and to determine their natural 

 sequence, and with this help you were able to demonstrate the 

 existence of important overthi-usts in that area. The peculiar 

 features of the ' pillow-lavas ' intercalated in the Upper Devonian 

 also engaged your attention, and your paper on the ' spilitic series,' 

 written in collaboration with Dr. Flett, has proved a valuable 

 contribution to Petrology. Of not less consequence, of another 

 kind, were your paper on the Eaised Beach of North Devon and 

 that which you read before this Society a year ago on the Origin 

 of River- Gorges in Cornwall and Devon. Your removal from the 

 West of England to the Thames A^alley introduced you to new 

 problems, to which you have brought the same zeal and insight, 

 and it is our hope that you will find in the present Award an 

 incentive to fui-ther investigations in the field of G-eology.
