Special interest attaches to the Stream Tin and "Wolfram Deposits, 

 and we wonder why the illustrations of these deposits, of so much 

 practical as well as general interest, are not reproduced from the paper 

 communicated to the Geological Society in 1908 by Mr. Barrow. To 

 the greater number of residents it is probable that the subject would 

 be more attractive than the petrographical descriptions (important as 

 they are) which occupy nearly half the memoir. 



In the chapter on Economics there are accounts of the famous slates 

 of De la Bole, of the Cataclews rock (proterobase), the De Lank granite, 

 and the China, clay, the metal-raining, and water-supply. 



Reference is made to the ancient British cemetery at Harlyn Bay, 

 and mention might appropriately have been made, in a footnote, of 

 the pamphlet by the Rev. R. Ashington Bullen on " Harlyn Bay and 

 the discoveries of its Prehistoric Remains ", 2nd ed., 1902. 



IV. — English Provincial and Scottish Geological Societies. 



Liverpool Geological Society. — The Proceedings .of this Society 

 (vol. xi, pt. i, 1910) contain a brief account of the celebration of 

 the Society's Jubilee, and the Address which Professor J. W. Judd 

 delivered on that occasion on " The Triumph of Evolution : a retrospect 

 of Fifty Years". This subject has been more fully dealt with by 

 him in a recently published work entitled The Coming of Evolution. 

 Mr. T. H. Cope writes " On the Recognition of an Agglomerate " ; and 

 Mr. C. B. Travis gives particulars of some borings carried through 

 Glacial Drift into Keuper and Bunter Sandstones near Burscough, 

 north of Ormskirk. He draws attention to the evidence of a buried 

 pie-Glacial valley. In one boring the Drift was 240 feet thick. 



Liverpool Geological Association. — In the part of the Proceedings 

 (New Series, No. 4, 1910) which contains records of the sessions 

 1907-9, Mr. C. B. Travis gives some useful hints on "Field Work 

 among Igneous Rocks " ; Mr. J. G. Learoyd deals with " Pressure in 

 relation to Thickness of Ice " ; Mr. T. A. Jones discusses the " Augite 

 Porphyrite ; ' of Scarlett Stack, Isle of Man, a rock which he regards 

 as a decomposed basalt and the remnant of a lava-sheet ; and 

 Mr. H. W. Greenwood considers " Some Problems in Bock Genesis 

 aud Metasomatism". 



Yorkshire Geological Society. — In the well-illustrated Proceedings 

 of this Society (n.s., vol. xvii, pt. ii, 1911) Dr. Wheelton Hind describes 

 four new species of Nautiloicls, including one new genus, Cyclonautilus,

 ferous rocks of Yorkshire and Lancashire ; Mr. Frank W. White 

 gives a detailed account of the complex of igneous rocks at Oatland, 

 Santon, Isle of Man, with micro-sections of the rocks; Mr. E. A. 

 Newell Arber contributes an article on the Fossil Flora of the Coal- 

 field in North Derbyshire and Nottinghamshire, illustrated by eight 

 excellent plates of fossil plants; and Mr. G. W. Lamplugh has 

 written obituary m-emoirs (with portraits) of C. Fox-Strangways 

 and J. 11. Dakyns.
