by Miss Andrews at Portstewart and at Kilkeel, by Mr. H. J. 

 Seymour, F.G.S., away down at Waterford and Youghal, and

 at Whiting Bay and other Cork localities. 4 



Its absence from 10 of our localities is worth analysing, as 

 in some cases this seems to tally with other circumstances sug- 

 gesting a special period for these deposits. Although none was 

 found at No. II., a drift-filled valley on Fair Head, fragments 

 occur as loose drift half a mile away. Gleno, VI., Cave Hill, 

 XV., and Divis, XIX., are small deposits of very local rocks ; 

 Wolfhill, XVIII., and Dungannon, XXX., have not been fully 

 investigated, and Killough, XXXIII., and Bloody Bridge, 

 XXXV., have special features suggesting that they may be the 

 product of later local glaciations. Although none was found in 

 Castle Espie, XXVIII., boulder clay, fragments are frequent as 

 loose erratics on the shore of Strangford Lough, XXIX., and 

 Mr. J. O. Campbell found an isolated morsel on Spinkwee moun- 

 tain in the Mourne range. In spite of careful search, Mr. Bell 

 never found any west of the Bann until this year, when he 

 picked up a solitary piece on the shore of Lough Neagh, near 

 Moyola River. 



Passing southward to No. III., the esker ridges about 

 Killagan and Glarryford, we have another very important sign 

 of an unsuspected icefiow to the N.N.W., in the frequent occur- 

 rence of Templepatrick rhyolite, the ]atter place lying some five 

 and twenty miles S.S.E. We found rhyolites also at Bally- 

 mena, IV., near Cookstown Junction, IX., in boulder clay at 

 Macedon, on the western shores of Strangford Lough, and away 

 down at Newry, XXXIV. 



Turning for a moment from, the rhyolite fragments in 

 Killagan eskers, let us read an extract from Mr. Maxwell Close's
