Great Britain, and stated that he was engaged in working out 

 the distribution of these valleys in the Counties of Antrim and 

 Down, and hoped to be able to lay the results of his work before 

 the Club at a later date. The last lecture of the season was an 

 extremely interesting one, on " Limestone," by Mr. William 'Gray, 

 M.R.I. A., illustrated with numerous specimens. 



Our Committee forwarded, at the request of Dr. Dwerryhouse, 

 a report of their recent glacial work to the British Association 

 " Erratic Blocks" Committee. Particulars were sent of "erratics" 

 found in Co. Armagh, Co. Tyrone, Co. Down, Co. Antrim, and 

 Co. Londonderry. The extension of Ailsa Craig riebeckite-eurite 

 to Coleraine was noted, and the occurrence of granite, probably 

 from Barnesmore Gap (Co. Donegal) in the Sandhills at Port- 

 stewart, recorded. A note of Mr. Robert Bell's discovery of 

 Lithostrolion Portlockii in boulder-clay overlain with about 7 feet 

 of peat, at Sluggan Bog, Drumsough, was also forwarded. 



The Committee desire to acknowledge with thanks, a kind 

 donation of Victorian zeolites from the Director of the National 

 Museum, Melbourne, also a fine collection of rock specimens, 

 fossils and flint implements from Mr. W. F. de Y. Kane, D.L. 

 This collection includes fossils from the shale and Carboniferous 

 sandstone of Ballycastle, from the Carboniferous limestone of 

 Co. Monaghan, and from the Oolite near Bristol ; also flint 

 scrapers and knives from Les Eyzies, South France. The thanks of 

 the Committee are due to Mr. M 'Henry, M.R.I. A., and to Professor 

 Seymour, B. A., F.G.S., for their kindness in determining erratics; also 

 to Madame Christen for investigating boulder-clay at Ballywalter. 

 The following continuation of the Section's glacial work during 

 the past year is appended. XLVTIIa. Armagh* — Esker S.W. of
