a ‘platform’ at 1,000 feet above sea-level. In my paper on the 
Arran Granite (Trans. Geol. Soc. Glas., vol. x, p. 216) I notice 
the immense denudation that had taken place in Arran when the sea 
worked at 600 to 1,300 feet above present sea-level, and give sections. 
I also note the fact that all the glens (with one notable exception) 
occur in synclines of the granite slabs, and all the mountains have 
the slabs arranged as anticlines or quaquaversal dips (with one 
exception). J have also shown by a diagram that the slabs dip 
all round the granite area (which is nearly circular) at from 15° to 
45° towards the slate, and give what I consider to be an explanation 
of these features. I also note the principal glacial phenomena, the 
thickness and quality of the Boulder Drift, moraines, etc., and how 
the drift had been carried all round the granite area on to the slate. 
I may say here that I saw no boulders foreign to the island on the 
granitic area, which is about 41 square miles. I do not, of course, 
suppose that all the immense denudation noted above took place 
during the Glacial Period—probably only a very small part of it. 
It is my firm opinion that the slate partly filled what are now the 
valleys at one time, and being more easily denuded than the granite 
this gave the original direction to the valleys or glens. In other 
papers I have shown that there is no Arran Granite in Ayrshire, 
except small bits along the shore which may have been brought as 
ballast.

7tH Battarion Royat Dusiin Fusiniers, GEOLOGIST ON THE 
GroLocicaL SurvEY or IRELAND. 
BoRN APRIL 16, 1890. DIED APRIL 30, 1916. 
Lizvr. R. L. Vatenrine, of the 7th Battalion Royal Dublin Fusiliers, 
who died from wounds in France on April 30, 1916, was born on 
April 16, 1890, at Portora School, near Enniskillen, where his father 
was classical master. He was educated at the High School, Dublin, 
and gained a scholarship in the Royal College of Science for Ireland, 
receiving the Associateship of the College in 1912. He especially 
devoted himself to natural history and geology, and was engaged on 
a research in 1913-14 as to the horizon of the lowest Avonian strata 
at Hook Head, co. Wexford. He obtained by competition the post 
of Geologist on the Geological Survey of Ireland, and completed the 
Civil Service qualifying examination while in military training at the 
_ outbreak of the War. He gave high promise of becoming prominent 
amongst scientific men in Ireland, and his unfailing cheerfulness and 
readiness of resource endeared him to those who looked forward to 
working with him as a colleague.
