ENGLISH AND IRISH CAVES. 



The Netherworld of iVlendip: Explorations in the Great Caverns 

 of Somerset, Yorkshire, Derbyshire, and elsewhere. B}- ErnesT A. 

 Bakrr, ma., and HERBERT E. Batch. 8vo. Pp. 12 + 172. Man}- 

 illustrations. Clifton : J. Baker, 1907. 



Mr. Baker is well known as an intrepid cave-explorer, and as a writer 

 of breezy and picturesque descriptions of caverns, and of the often 

 exciting and dangerous work which attends their exploration. In the 

 present most readable volume he describes a number of the more famous 

 English caverns, and narrates the story of various attempts — sometimes 

 successful, sometimes unsuccessful — to penetrate their recesses In the 

 final chapter he deals with the famous cave of Mitchelstown, and gives 

 an account of his visit there in 1905, with results which he has already 

 reported in this Journal (/. Nat., vol. xv., pp. 29-36. Plate i ) The work 

 is profusely illustrated with subterranean photographs — some of which 

 are notably successful examples of a difficult brancli of cave work — and 

 can be confidently recommended both to the cave-explorer and to the 

 general reader.

The present is the fourth issue of this valuable annual, which cannot 

 fail to be useful to naturalists and to men of science generally, the ar- 

 rangement of the diary, engagement lists, and other practical details 

 being especially convenient. The information in the Directory still 

 needs revision ; although the staff of the Irish Geological vSurvey is now 

 given correcth\ Col. G. T. Plunkett still appears as Director of the Dublin 

 Museum, and the late T. H. Longfield as Art Keeper, while the name of 

 Prof A. Dendy has not yet been included among the scientific staff of 

 King's College, London, nor that of Prof Gregg Wilson in Queen's 

 College, Belfast.
