and, it is supposed, lignite at one place. These overlie the basalt, which 

 spreads over a large area to the north and west around Portadown &c., 

 with isolated patches near Markethill, and at Pointspass to the south- 

 west. It is in general hard, dark grey and finely crystalline, very 

 amygdaloidal and zeolitic, and weathers in spheroids. Prof. Hull gives 

 " Microscopic Notes " of that near Ballyleny, which consists of a sub- 

 crystalhne augitic base, with many prisms of triclinic felspar (Labra- 

 dorite) ; magnetite or titano-ferrite, olivine, and chlorite also are present. 

 It is a fair sample of the basalts of the north-east of Ireland. 



Mr. Baily furnishes *' Paloeontological Notes," with list of fossils, 

 and fossil localities. He notices the absence of Goniatites, as weU as 

 Orthoceratites, in the Carboniferous Limestone — also the abundance of 

 fish-remains in the Armagh marble, being for the most part palatal 

 teeth and defence-spines of fish allied to sharks and rays, in general 

 character corresponding to the fish-remains of the Carboniferous Lime- 

 stone near Bristol and at Farlow. The memoir contains a " Detailed 

 Description " of all the foregoing, and a short notice of the Drift. This 

 consists of Lower Boulder Clay, with overlying sands and gravels ; the 

 latter contain occasionally fragments of shells and pieces of silicified 

 wood. E. T. H. 



Ellis, J. W. Note on the Stump-Cross Caverns at Greenhow, near 

 Pately Bridge. Eep. Brit. Assoc, for 1873, Sections, p. 80. 



These caverns were discovered in 1860 by miners searching for lead, 

 at a depth of 9 fathoms from the surface. They are remarkable for 

 the great beauty of their stalactites. W. T. 



Etheridge, R. On the Geology of Coal and Coal Deposits in the 

 British Islands. Beport of Proceedings 11th Annual Meeting, 

 British Association of Gas Managers, pp. 84-109. 



Describes the range of Carboniferous rocks of Western Europe, and 

 then refers in more detail to the British Coal-fields, giving for each area 

 the results of the Coal-Commission Report, statistics of produce, quan- 

 tity still remaining, &c. The " concealed Coalfields " are referred to, 

 and the possibility of the existence of Coal Measures beneath the S.E. 

 of England is discussed. The paper concludes with notes on the Flora 

 of the Coal. W. T. 



Etheridge, R., jun. Description of a Section of the Burdiehouse 

 Limestone and connected Strata at Grange Quarry, Burntisland. 

 Trans. Edin. Geol. Soc. vol. ii. part iii. pp. 273-270. 



Describes a new exposure of the Burdiehouse Limestone at the Grange 

 Quarry near Burntisland. The measures consist, in descending order, 

 of: — 1. A thick sandstone with fragmentary remains oi Le^idodemlron 

 and Stiffmaria ; 2. Two beds of flaggy shales, separated by a thin course 

 of black friable shale and containing species of Lepidodendron, Eury- 

 notiis crenatits, PalcBoniscuSf sp., Leperditia Scoto-hurdigalensisj Beyrichia 

 (U'cnata, and Kirkhya annectens ; 3. Friable black shales with Sphe- 

 nopteris affinis ] 4. Limestone, 12-14 feet in thickness, with Leperditia 

 Scoto-burdiyalemis and iStiymaria-rooilGts. H. A. N.
