in large measure buried under a continuous mantle of ice which 

 moved outward in all directions towards the sea. Some of the 

 earlier papers which helped forward the adoption of this explanation 

 of the phenomena were published in our Quarterly Journal ; those 

 of A. C. Ramsay ^ and T. F. Jamieson ^ were specially effective. 



While we may reflect with no little pleasure that the Geological 

 Society can claim to have had a conspicuous share in starting the 

 active study of the glaciation of Britain, not less satisfaction may be 

 derived from the part taken by the Society in the great subsequent 

 development of the subject. The growth of Pleistocene literature 

 during the latter half of last century has been one of the most 

 remarkable features in the modern advancement of geology, and a 

 large portion of this literature, including some of its best parts, has 

 been given to the world in the volumes of the Quarterly Journal. 

 Thus, in looking through these volumes, the geologist will find that 

 the march of the ice-sheet over the Shetland Isles has been followed 

 by Dr. Peach & Dr. Horne,^ and over the Outer Hebrides by Prof. 

 James Geikie.* The later stages of the Ice-Age in IS'orthern Scotland 

 have been traced by Mr. Jamieson. The relics of some of the last 

 glaciers in the Southern Uplands have been described by the late 

 Prof. John Young.^ The glaciation of the Eden Yalley and the west 

 part of Yorkshire has been explored by the late J. G. Goodchild ^ ; 

 that of the Lake District by the late J. C. Ward ^ and D. Mackintosh.^ 

 Mr. Mellard Reade has furnished papers on the Drift of the north- 

 western counties and of the Yale of Clwyd,^ while Mr. Tiddeman 

 has given an account of the traces left by the ice-sheet from York- 

 shire through North Lancashire into Westmorland.^" Dr. Strahan 

 has discussed the glaciation of South Lancashire and the Welsh 

 border ^^; Dr. Dwerryhouse that of Teesdale, Weardale, and the 

 Tyne Yalley.^^ Prof. Kendall has drawn a suggestive picture
