" WEST YORKSHIRE." * Parts I. & II. 

 We hail" with pleasure the tardy appearance of this long promised 

 volume, and though not yet complete it is a welcome instalment. The 

 first 228 pages are devoted to the Geology of the District, by the pen 

 of Mr. Davis, illustrated by a number of diagrammatic drawings 

 of local sections, five geologically coloured plates of more general 

 sections across the country in various directions, and a map (4 inches 

 to the mile) exhibiting the area of the different formations and their 

 relative positions. The remainder of the volume, which is of joint 

 authorship, is devoted to . Physical Geograj^hy, and Botanical Topo- 

 graphy, illustrated by a map on the same scale as the geological one, 

 coloured to show the divisions of the river drainage ; these drainage 

 areas are divided into ten, viz : — the Lune, Ribble, Mersey, Ure, 

 Nidd, Wharfe, Aire, Calder, Don, and Trent. One chapter is devoted 

 to each of these areas, which after giving the leading details of the 

 physical geography, and remarks on the scenery of the district, contains 

 a list of the principal and more remarkable plants and mosses found 

 therein, and in many cases with critical remarks upon them. We 

 regret to have to notice one or two inaccuracies in this portion of the 

 work, as at p. 349 where the R. Ribourne is stated to run north-west 

 instead of N.E. : again the "Ivy-leaved Bell-flower" is in some 

 instances referred to as Campanula, and in others as WaJdeubergia 

 Jiederacea : some varieties are printed as if they were species, e.g. p. 354 

 Blindia tricliodes^ instead of B. acuta var. /3 tricJwdes ; Cardamine amara 

 is certainly not indigenous in Storthes Hall Woods, and surely Ceratodon 

 purpureiis is too common a moss to merit special mention. 



The geological portion is as complete and exhaustive as the space 

 will allow, and is indeed a production worthy of its author, who has 

 evidently spared no pains to render the subject as clear and compre- 

 hensive as possible. A most useful and interesting addition to it is, 

 the 40 pages devoted to the bibliography on the geology and physical 

 geography, commencing with A.D. 1674, arranged iii years, and con- 

 taining 491 references. We can cordially congratulate the authors on 

 the production of their first volume, and trust that the second, which 

 is to contain complete lists of the flowering plants, ferns, mosses, 

 lichens, and fungi, will speedily follow, and that before this year closes 

 we shall have that basis to work upon in botanical science which is so 

 great a desideratum with us at present.
