xlvi PKOCEEDINGS OE THE GEOLOGICAL SOCIETr. [Jlllie I912,- 



Tees and other northern rivers, I got the impression that it was a 

 model of scientific exposition, an opinion confirmed when I saw 

 it in print. Bnt this represents only a part of the service that you 

 have rendered to the Glacial Geology of the I^orth and Midlands of 

 England and of the J^orth of Ireland. In each locality you have 

 discovered something new and something throwing fresh light 

 upon the conditions that prevailed during the Glacial Epoch. But 

 you have also been able to pursue enquiries along other lines; for 

 instance, the circulation of underground waters, the origin of caves,, 

 and the weathering of rocks ; while in your Presidential addresses 

 to the Liverpool Geological Society you have dealt with far larger 

 geological problems. As a contributor to the ' Glacialists' Magazine,' 

 as Secretary for several years of Section C of the British Association, 

 and as a member of the Committee on Erratic Blocks, you have 

 discharged other duties to your Science. In your papers on the 

 Eskdale Granite and its metamorphism, you have approached a 

 difficult petrographical problem, and made an important contribution 

 to its solution. Finally, your recent work on geological maps will 

 be of great help in educating students to deal in the laboratory with 

 geological problems which they will have later to face in the field. 

 I have the pleasure to hand you a moiety of the Balance of the 

 Proceeds of the Lyell Geological Fund. 



The Pkesident then presented the other moiety of the Balance 

 of the Proceeds of the Lyell Geological Fund to Robeet Heeox 

 Rastall, M.A., addressing him as follows : — 



Mr. Eastall, — 



It is fitting that both authors of so novel and important a work 

 as ' Lake and Rastall's Textbook ' should receive awards from the- 

 Geological Society on the same occasion. In making this award,, 

 however, the Council had in mind not only that work, but the labour 

 which you have for many years devoted to your Science in original 

 research. You have been attracted most strongly by petrogra- 

 phical problems, as is indicated by your contributions to Dr. Hatch's- 

 w^ork on that subject, and by your papers on the igneous rocks of 

 Buttermere and Enuerdale, on the inclusions in the Mount-Sorrel 

 granite, on the Skiddaw granite, on the rocks surrounding the 

 Kimberley diamond pipes, and on the dedoloraitization of marble 

 at Port Shepstone. One might perhaps even venture to think that
