Robert Young, Esq., C.E., read a Paper on 



SOME NOTES ON THE UPPER BOULDER CLAY 



NEAR BELFAST. 



Mr. Young prefaced his paper by referring to his paper of last 

 session describing the sections at the Greencastle Water 

 Reservoir, where the remains of a yew tree forest in the boulder 

 clay was exposed. Above this there is a thin bed of vegetable 

 matter, which is succeeded by a covering of upper boulder 

 clay. This locality is 200 feet over sea level. Since then, he 

 stated, he has found at Ligoniel what he believes is another 

 patch of the boulder clay referred to, in which a portion of a 

 small yew tree was also discovered. The interesting point is that 

 at this place there is no lower boulder clay or intervening 

 vegetable bed, but the upper clay rests directly on the surface of 

 the keuper marl beds. The paper was illustrated by diagrams, 

 and by various objects found in the excavations. 



Mr. William Gray, M.R.I.A., offered some criticisms. 



H. Pearce, Esq., read 

 NOTES ON A COLLECTION OF BUTTERFLIES. 



Of the sixty-six varieties of Butterflies contained in the 

 collection, forty are to be found in Ireland. Mr. Pearce gave 

 a description of the different varieties of Butterflies which 

 he presented to the Museum. The paper was illustrated by 

 diagrams and limelight views. 



The Rev. John Bristow, in criticising the paper, stated that 

 he had found last summer, at Ballycastle, several specimens of 

 the moth Nyssia zonaria, which was thought to be exclusively 

 confined to the district of the Mersey, in England. He 

 mentioned that he has in his collection a specimen of the 

 Camberwell Beauty (V. Antiope), which was taken on a wall 

 near Parkmount, Belfast.
