 On some Post-glacial Ravines in the Chalk-Wolds of Lincolnshire. [Geol. 

 See, December 5th, 1883.] Geol. Mag., January, p. 45 ; and Science Gossip, 

 April, pp. 93-94. 



Describes Post-glacial deposits in Swaby Yale, the valleys near Louth, and 

 near Caistor, stating too that these valleys are among the most remarkable 

 instances of river erosion to be met with in England. Notes where the modern 

 watercourses, after flowing for some distance along the line of an ancient (pre 

 boulder-clay) valley, suddenly deserts that valley and passes through a 

 ravine excavated entirely out of the chalk.

 the Eskdale granite ; the Ennerdale syenitic-granite ; and the Carrock Fell 

 hypersthenite. Mineral veins and their geological distribution, their direction 

 and hade, length, breadth, and depth, and their inner nature. List of minerals

 On a Eecent Exposure of the Shelly Patches in the Boulder- CI ay at 

 Bridlington. Quart. J. Geol. Soc, xl. 312-328, with woodcut; Geol. Mag., 

 April, p. 185 ; and Ann. and Mag. Nat. Hist., April, p. 297. Abstract in 

 Proc. Geol. Soc, February 20th, 1884. 



Description of the 'Basement Boulder-Clay' thus exposed, with theory as to 

 the origin of the shelly patches contained. Details of fossils discovered 

 (number of Mollusca raised from 67 to loi, five of them being new). This 

 paper is to prove that the shelly patches are not in place, but are remnants of 

 beds which once existed on the spot, ploughed up and destroyed by the 

 passage of ice over them, or else they have been far transported and here 

 abandoned by the ice in its progress.

 Board on the sanitary condition of the district, folio (Blue Book).

G. A. Lebour. Durham. 

 On the Breccia-gashes of the Durham Coast and some recent Earth-shakes at 

 Sunderland. Proc N. of Eng. Inst, of Mining and Mech. Engineers, vol. 

 xxxiii. 1884, pp. 165-174, and plates xii., xiii. 



This paper draws special attention to one of the strangest and most striking 

 of the developments of the Magnesian Limestone, as displayed in Marsden Bay. 

 The breccias are exposed on the cliff face between walls of ordinarily bedded 

 Mag. Limestone, and present many peculiarities which are noted in detail, and 

 their varieties also illustrated by diagrammatic sketches. Their origin and 

 their connection with the recent earth-shakes at Sunderland are discussed at 

 length. 



G. A. Lebour. Northumberland. 

 On a Great Fault at Annstead, in North Northumberland. Proc. of N. of 

 Eng. Inst, of Mining and Mech. Engineers, 1884. 



This paper draws attention to and describes one of the most complete 

 natural sections, and one of the greatest dislocations in Northumberland. 

 The probable throw of the Annstead Fault is 980 feet. The beds described 

 are Upper Bernician or Yoredale. A detailed section of the strata from Ebba's 

 Snook to Annstead Burn given.
