rests, at different points, on fine red sand, gravel, or fine red clay ; but before 

 we have reached low-water level, we come upon the coarse Boulder Clay with 

 pebbles, which at this place is therefore some ninety feet higher than in the 

 Lagan Valley a mile to the westward, as shown by the King Street borings. 



This concludes my brief notice of the Post-pliocene deposits of the Lagan 

 Estuary. The Belfast beds have now been pretty well examined, and our 

 knowledge of them is tolerably complete ; but there is still an ample field for 

 research in the similar clays which are to be found in almost all our loughs and 

 bays ; and it is to be hoped that other members of our Club will devote some of 

 their time and attention to these interesting deposits— the latest page of the 

 great mysterious volume of geological history. The clay at Magheramorne is 

 famous for the profusion of Foraminifera, some of them of great rarity, which 

 it yields,* and its richness in large fossils is apparent from the fact that during 

 one visit— my only visit to it — no less than seventy-one species of fossils were 

 noted, Microzoa excluded. Further examination of this deposit will without 

 doubt result in considerable additions to this number.
