PROCEEDINGS OF THE GEOLOGICAL SOCIETY. [vol. lxxii, 



Dr. Lapworth, — 



The Balance of the Proceeds of the Murchison Fund has "been 

 awarded to Mr. G. W. Tyrrell in recognition of his contributions to 

 the petrology of South -Western Scotland. His keen petrographic 

 insight was first shown in his description of the quartz-dolerite sills 

 of Kilsyth. His results of most general interest to geologists are 

 those connected with the Palaeozoic alkaline rocks ; for his investiga- 

 tion of lugarite has added to petrology a peculiar rock-species and 

 important evidence in favour of the differentiation of igneous rocks 

 by the sinking of their heavier constituents. In several papers on 

 the Auchineden Hills he has described their igneous rocks and their 

 glacial and plrvsical features ; and, in his recent account of the 

 ravine known as the Whangie, he has advanced conclusive evidence 

 of its formation by earth -movements. As the Senior Assistant 

 in the Geological Department of Glasgow University, and later 

 also as Lecturer on Petrology there, he has done much towards the 

 development of that school of geology. 



The Council hopes that this award may encourage and assist him 

 in further research. 



Awards prom the Ltell Geological Fund. 



The President then presented a moiety of the Balance of the 

 Proceeds of the Lyell Geological Fund to Mr. Martin A. C. 

 Hinton, addressing him as follows 



Mr. Hinton, — 



The Council has awarded to jow a moiety of the Proceeds of 

 the Lyell Fund in recognition of your researches on the British 

 Pleistocene Mammalia, and as an incentive to further work of the 

 same kind. Under circumstances frequently discouraging, you 

 have for many years devoted yourself especially to the study of 

 the Rodentia and the Insectivora, and have obtained a remarkable 

 knowledge of the skeleton and teeth of certain groups Avhich are 

 most commonly met with among fossils. In this manner you 

 have made discoveries with an important bearing on many 

 problems of Pleistocene geology, which you have never failed to 

 recognize. As one who has followed your work with great interest 

 for several years, I have much pleasure in handing to you this 

 award.
