192 Ohihiary — Rev. J. E. Cross. 



the "General Committee" in 1862. During this period he com- 

 municated several papers: (1) "On the Action of Heat on certain 

 Sandstones of Yorksliire " (Proc. Geol. Assoc, vol. i, p. 50), when 

 he drew attention to the road-metal used near Huddersfield, and to 

 the custom of hardening the stone by the action of tire ; (2) " On 

 the Efflorescence which, succeeds the action of Heat on certain 

 Sandstones of Yorkshire" (ibid., p. 158); (3) "On the Plasticity 

 and Odour of Clay" (ibid., p. 237), in which he observed that clay 

 ceased to be plastic when deprived of its chemically combined water, 

 and that plasticity and other properties depend upon variations 

 in the attractive force of the molecules of matter according to the 

 distances apart of such molecules. The peculiar odour of clay 

 belonged only to impure clays, and chiefly to those containing 

 oxide of iron. H. B. W. 



THE REV. JOHN EDWARD CROSS., M.A., F.G.S. 



(Prebendary of Lincoln). 

 Born 1821. Died Febrtjaby 28, 1897. 



The Eev. J. E. Cross (brother of Viscount Cross) was educated at 

 Christ Church, Oxford, and was appointed to the curacy of Bolton- 

 le-Moors in 1846. Three years later he became curate of Appleby, 

 near Brigg, in Lincolnshire, and he was presented to the vicarage in 

 1866. In this quiet village he lived and laboured for thirty-five 

 years, retiring in 1891 to Grange-over-Sands. 



To geologists Mr. Ci'oss is known as the author of an excellent 

 paper on " The Geology of North- West Lincolnshire " (Quart. 

 Jonrn. Geol. Soc, vol. xxxi, pp. 115-130. Appendix by K. 

 Etheridge). In this work he described, for the first time in 

 detail, the Jurassic formations from the Lower Lias to the Corn- 

 brash, in the area bordering the south shore of the Humber between 

 the rivers Trent and Ancholme. It was, as he remarked, " a corner 

 of the land unknown to fame " until the discovery of the valuable 

 iron-ore in the Lower Lias at Frodingham. Long and diligently 

 had Mr. Cross worked, as shown by his careful record of facts, and 

 the numerous fossils he had collected. Several new species of 

 Mollusca were described by Mr. Etheridge. H. B. W.

Nkw Geological Survey Maps. — Attention was drawn in the 

 Geological Magazine for February, 1896, p. 96, to the General Map 

 of England and Wales (on the scale of four-miles to one inch), which 

 was in course of publication by the Geological Survey. We now 

 learn that the hand-coloured edition of this useful map is complete, 

 the fifteen sheets, including title and index of colours, all being 

 published. We called attention to the fact that Sheet 12 of this 

 map (London Basin and Wealden area) was issued last year at the 

 greatly reduced price of 2s. Gd., •printed in colours. We are glad to 

 announce that three other sheets have now been similarly pub- 

 lished, viz. : Sheet 6 (East Yorkshire), Sheet 9 (Eastern Counties), 

 and Sheet 15 (Sussex Coast). The price is uniformly 2s, Q)d.
