G. W. Lamplugh. East Yorkshire. 



Report on the buried Cliff at Sewerby, near Bridlington [this valuable 

 report is divided thus : — Introduction ; an ancient shore ; the old sea-beach ; 

 the old land-surface; the blown sands; the fossils; age of the beds; con- 

 cluding notes]. Proc. Yorks. Geol. and Pol. Soc, vol. ix. part iii. (1S87), 

 pp. 381-392, with plate. 

 R. Law and J. Horsfall. West Yorkshire. 



On the Discovery of Carboniferous Fossils in a Conglomerate at 



Moughton Fell, near Settle, Yorkshire [giving section and list of fossils ; 



abstract of paper read at Brit. Assoc. Meeting at Manchester]. Geol. Mag., 



Jan. 18S7, dec. iii. vol. v. p. 30 ; Rep. Brit. Assoc, for 18S7, p. 690. 



G. A. Lehour. West Yorkshire. 



Note on a Deposit of Lacustrine Marl in West Yorkshire [occupying the 

 bottom of the Crummock Valley between Moughton Fell and Norber ; the 

 marl was pure white, like crumbly chalk, and was almost entirely made up of 

 fresh-water shells, chiefly of the genera Litmiaa and Cyclas ; a thin layer of 

 peaty vegetable matter divides the white marl]. Nat., Aug. 18S4, pp. 16-17. 

 G. A. Lebour. Durham. 



Note on an Abnormal Deposit of Drift Coal in North Durham [at a small 

 sandpit near the working-shaft of St. Andrew's Colliery, worked for a fine 

 brown sand which rests upon boulder clay, is a much false-bedded mass of 

 sand and gravel of various degrees of coarseness ; on one side of this sand-pit 

 was a bed of rolled coal of more than two feet in thickness, dipping steadily 

 S.E. ; the coal pebbles contained were exceptional in size and unlike any 

 coal-measure coal known in the district ; analysis of coal given : — Volatile 

 matter i7 - o,Red Ash 17-4, Fixed Carbon 65-6]. Nat.,Mch. 1885, pp. 179- 1S0. 



G. A. Lebour. Durham and North- East Yorkshire. 



On the Stratigraphical Position of the Salt Measures of South Durham 



[abstract of paper read before British Association, 1S86 ; gives classification 

 of strata from base of Permian to Rhastic ; the salt measures are considered 

 to represent probably the Upper Permian or Ranchwackc of Germany]. Geol. 

 Mag., Jan. 1887, dec. iii. vol. iv. p. 39. Brit. Assoc. Rep. for 1886, p. 673. 



G. A. Lebour. Northumberland, Durham, N.E. York. 



Outlines of the Geology of Northumberland and Durham [the geological 

 formations are treated in order from above downwards ; special attention 

 is given to the Carboniferous system, chapters being devoted to the Coal 

 Measures, the Canister and Millstone Grit series, the Bernician rocks, and 

 the Tuedian series ; the small inliers of Silurian beds in Northumberland 

 and Teesdale are described ; the Igneous rocks of the district are duly 

 noticed, including the dykes, the Whin Sill, and the granites and felsites of 

 the Cheviots : extensive lists of Carboniferous fossils are given]. Svo, cloth, 

 156 pp. and 5 plates, including maps of Northumberland and Durham, and 

 part of Cleveland ; see Review in Nat., Sep. 1887, p. 28S. 



G. A. Lebour. Northumberland and Durham. 



Sketch of the Geology of Northumberland [describing the physical features of 

 the county, the inliers of Silurian, the Cheviot ' porphy rites,' the whole 

 Carboniferous system, with the Whin Sill, the Permians of Durham, and the 

 superficial deposits; a map and sections are given]. Proc. Geol. Assoc, 

 vol. ix. pp. 555-575, 1887.

of the Humber, forming a lake which extended westward to the Pennines and
