and Fossils belonging to the Geological Survey of Ireland,' 

 produced in collaboration with Prof. Watts in 1895 (new ed. 

 1898), comprises much more than its title implies, and constitutes, 

 in fact, an excellent general sketch of the geology of Ireland. 

 McHenry also participated in the later mapping of the Drifts in 

 the country around Dublin, Belfast, Cork, Limerick, and London- 

 derry (1901-1906), and contributed subsequently to the preparation 

 of a special memoir on the Interbasaltic Rocks (Iron-Ores & 

 Bauxites) of North-East Ireland (1912). 



Most of McHenry's work was published officially ; but, besides 

 his contribution (jointly with Mr. J. B. Kilroe) to our Journal in 

 1901 on ' Intrusive Tuff-like Igneous Bocks & Breccias,' a few 

 separate papers by him are contained in the Proceedings of the 

 Boyal Irish Academy, the ' Geological Magazine ' (1895), the Pro- 

 ceedings of the Geologists' Association (1895), and other journals. 

 Though of strong convictions in matters geological, McHenry was 

 endowed with a spirit of tolerance and humour which rendered 

 any argument delightful, and made him at all times the most 

 cheerful of comrades. Devoted to his family, kindly and affec- 

 tionate in every relationship with his fellows, he went through life 

 gently, and had the good- will of all. He died in Dublin, after a 

 short illness, on April 19th, 1919, in his 76th year. 



Some Features of the Pleistocene Glaciation 

 oe England. 



Introduction. 



I propose to use the present opportunity to review the changes 

 brought about in the surface-features of our country by the 

 Pleistocene glaciation, and incidentally to apply on a broad scale 

 some inferences respecting the origin of these features, which have 

 been deduced from the study of particular tracts. In what I have 

 to tell there will be little or nothing that has not been already told 

 somewhere or other in our voluminous Glacial literature ; but I 

 hope that a rearrangement and restatement of the scattered 

 material in fresh perspective may be found useful.
