and Westmoreland undoubtedly are, but Lough Shannagli maybe in part. 

 The others are probably formed by dams of boulder clay squeezed up 

 on the side of the ice-stream of the main valleys. A most interesting 

 feature is the rugged character of the hill-.tops generally in the British 

 Isles above a level of something about 2,500 feet, showing that the ice, 

 from whatever source derived, did not rise above that level. The sum- 

 mits of Sea Fell, Helvellyn, Ben Nevis, and Slieve Donard are all a mass 

 of large boulders apparently the result of sub-aerial weathering, the 

 lower hills have all been swept bare. In the course of the subsequent 

 discussion, Mr. J. O. CampbEI.1. mentioned finding Ailsa Craig eurite as 

 an erratic in the Spinkwee valley of the Mourne mountains, also an 

 apparently Antrim flint on the Aran Islands. A portion of the British 

 Association " Erratic Blocks " report, containing a reference to glacial 

 work done by the Club, was followed by a paper on the Silurian rocks of 

 Pomeroy, by Mr. R. Bei<I/, who also contributed erratics from boulder 

 clay at an elevation of 1,300 feet between Divis and Black Mountain, 

 including Ailsa and Tormamoney eurite. Rock specimens were pre- 

 sented by the Hon. Sec. 



November 30th.— The opening meeting of the new Botanical Sec- 

 tion of the Club was held in the Club Rooms at the Museum, on 

 Saturday afternoon. It was decided to meet on the last Saturday in 

 each month at four o'clock, and to devote the first hour to structural 

 botany and practical work with the microscope, and the remaining time 

 to the study of the natural orders of British plants. Some notes were 

 then given by Rev. C. H. Waddell, on protoplasm and chlorophyll. 

 Papers and short notes have been promised on " Sedges," " Hieracia," 

 " Alien plants," "Duckweeds," &c. The meetings are open to all who 

 are interested in botany, and the names of any persons who wish to 

 join should be sent in to the Secretary, Rev. C. H. Waddell, Saintfield. 



December 13th.— Microscopicai, SECTiON.—Dr. Lorrain Smith lec- 

 tured on " The Study of Bacteriology." 



December 17th. — The President (Mr. F. W. Lockwood) in the chair. 

 The President read a short note on the gravels at Lame, Co. Antrim, 

 which will appear in our next issue. 



Miss Nora Steen contributed a short paper on Craiganogh cave, 

 Co. Antrim, which we hope to publish shortly. 



Mr. Robert BE1.1. read a paper entitled "A Day among the Silurian 

 Shales of Pomeroy." The paper dealt with the results of a visit in last 

 July. These shales are very interesting, being the nearest place where 

 those characteristic Palaeozoic crustaceans, the trilobites, can be 

 obtained. Mr. Bell's experience in expending half the time at his dis- 

 posal in searching for the beds, in spite of full instructions kindly given 

 by Mr. M'Henry, M.R.I. A., is one common to many geologists. The 

 rough fossiliferous grits, with marks resembling sea-weeds and worm- 

 tubes, lie south of the granite hill at Bardahessiagh ; newer sandy beds 

 have been deposited uncomformably upon them. The trilobites occur 

 in a section cut by the river near Dickson's house and the slate quarry. 

 The fossils found were on view during the evening.
