IV. — Hampstead Hill: Its Structure, Materials, and Sculp- 

 turing. By J. Logan Lobley. With Chapters on the 

 Natural History of the District by H. T. Wharton, F. A. 

 Walker, and J. E. Harting. 8vo. pp. 100. With Nine Plates. 

 (London, 1889.) 



A USEFUL and readable companion to this interesting bit of 

 country which is carefully described and well illustrated. After 

 describing the geological structure of the Heath in detail, the author 

 reprints a series of well-sections from Mr. Whitaker's " London 

 Basin," gives a list of fossils which surprises by its fulness, and 

 appends a useful bibliography, to which, howevei - , may be added : 

 John Bliss, Experiments and Observations on the Medicinal Waters 

 of Hampstead and Kilburn. 4to. London, 1802, pp. 58, — a 

 pamphlet which seems to have escaped bibliographers in general. 

 There is also a mistake in the date of Goodwin's account of the 

 Saline Waters ; this interesting little book was published in 1804, 

 the author apologizing for the delay in publication in his preface. 

 Goodwin also adds a view of Pond Street in 1803 and gives a careful 

 and accurate map of " Hampstead with some of the adjacent villages, 

 and surrounding rides, 1803." Dr. H. T. Wharton contributes a 

 list of the Plants, the Eev. F. A. Walker, one of the Insects, etc., 

 and Mr. J. E. Harting writes on the Birds, giving notes of dates of 

 appearance of the rarer visitors and accurate information as to 

 their nesting places. Professor Lobley has wisely reproduced, by 

 permission of the Council of the Geologists' Association, the late 

 Mr. Caleb Evans' geological sketch map of Hampstead. C.D.S. 



V. — Mount Vesuvius : A Descriptive Histobical and Geo- 

 logical Account of the Volcano and its Surroundings. By 

 J. Logan Lobley. 8vo. With Maps and Illustrations. (London, 

 1889.) 



THIS new and revised edition of Professor Lobley's book fills up 

 a gap in the literature of Vesuvius. The most recent memoirs 

 on the subject have been laid under contribution, and the book is 

 both readable and comprehensive.

" On the Crystalline Schists and their Belation to the Mesozoic 

 Eocks in the Lepontine Alps." By Professor T. G. Bonney, D.Sc, 

 LL.D., F.E.S., F.G.S. 



In the debate upon the paper " On two Traverses of the Crystal- 

 line Eocks of the Alps " (read Dec. 5, 1888) it was stated that rocks 

 had been asserted on good authority to exist in the Lepontine Alps, 

 which contained Mesozoic fossils, together with garnets, staurolites, 

 etc., and thus were undistinguishable from crystalline schists re-
