mica-schist, chalk, flint, basalt, vein-quartz, red granite, red quartz- 
porphyry. 
Siream section below Drumnacoll (340 feet): Section consists of 
3. Coarse gravel (water worn). 
2. Current-bedded sand. = 100 feet. 
1. Red Boulder Clay. 
The bed (1) contains basalt, chalk, mica-schist, gneiss, vein-quartz, 
flint, and calcareous sandstone with lustre-mottling (Carboniferous). 
Near Retreat Station, Glen Ballyemon [Sheet 14]. Country Rock— 
Basalt: In boulder clay, flint, chalk, Old Red Sandstone, Old Red 
Sandstone conglomerate, quartzite, mica-schist and vein-quartz. 
Friar’s Glen, three miles N.N.W. of Soldierstown [Sheet 36] (100 
feet). Country Rock—Basalt: Hornblende diorite, quartzite, coarse 
red muscovite-granite, andesite. These are all from the district round 
Pomeroy. Also Carboniferous sandstone, flint, and vein-quartz. 
During the year thin sections of a number of Irish erratics have been 
prepared, and the Secretary has visited Arran and Bute with the object 
of ascertaining how far the rocks of those islands have contributed to the 
glacial deposits of the North of Treland, and has collected a number of 
specimens for purposes of comparison. Tt is hoped that the results of 
this investigation will be published in the next report of the Committee.

Committee to the series of questions submitted to them for consideration 
by the Chairman “and Secretary. These replies were codified and 
embodied in a circular letter which was sent in April to the members of 
the Committee and to a number of specialists in the paleontology of the 
various geological formations. 
The members of the Committee unanimously approved of the @eg- 
gestion that a small sub-committee of experienced teachers should be 
asked to draw up a list, in the first instance, for presentation to the 
Committee and the specialists. Some members, however, pointed out 
that the list of fossils adopted by the University of Cambridge, and 
which had stood the test of many years’ practical use, was in print, 
and suggested that this might very conveniently be adopted as the basis
