598 REVIEWS. [July, 



to any advantage. Scientific classification proceeds from exactly the same 

 source, — the inability of the mind to receive a mass of unarranged parti- 

 culars." 



" Those who make foolish objections to systems of names as dry and 

 unprofitable, may be reminded that the most valuable discoveries in science, 

 and generally in philosophy, have been merely fresh combinations of facts 

 known before. If there be a distinction between the classification of science 

 and that necessary to every-day business, it is this, that in the latter the 

 distinctions are precise and the method symmetrical, while in the former 

 both are, for the most part, rough and arbitrary." 



A list of the plants, or rather of the rare plants, in the Craven 

 and south-west districts of Yorkshire, would be labour and cost 

 wasted. Lists of Ardenne and Lorraine plants may be of some 

 use to inform those who will never see M. Crepin's and Dr. 

 Godron's works, that plants grow in these provinces common to 

 both England and Belgium and France, and that there are many 

 plants to be found in these Continental countries which we have 

 not in the British Isles. But such lists would be quite super- 

 fluous here, because everybody who means to visit the places 

 above mentioned, and which have been familiar since the times 

 of Ray, Dr. Richardson, Th. Willisel, Mr. Lawson, Wm. Curtis, 

 Sir J. E. Smith, etc., will purchase this work, carry it in their 

 pocket, and wear it out by frequent consultation of its instructive 

 pages. 



The size of the book may be estimated from the fact that the 

 pages filled up with the Phsenogamous plants of the district are 

 just fifty-one, and the Cryptogams occupy thirty-seven. The latter 

 portion is, as above stated, by Dr. Carrington, who professes his 

 obligations to Mr. W. Wilson, Dr. Lindsay, Mr. Mudd, T. 

 Moore, Esq., F.L.S., Mr. Tom Stansfield, and other friends, who 

 aided the learned author " in the determination of species.''^ 



Special thanks are awarded to Mr. J. Nowell, of Todmorden, 

 in a separate article. 



Thanks are tendered to "the following gentlemen," who have 

 given the author " notes or lists of species :" — J. G. Baker, Esq., 

 L. Miall, Esq., Dr. Deighton, Mr. C. Hobkirk, Dr. Windsor, J. 

 Craraond, Esq., Rev. J. Finder, P. Inchbald, Esq., R. Clapham, 

 Esq., Mr. C. Eastwood, and the members of the Todmorden and 

 Thirsk Botanical Societies. 



Mr. Miall's obligations are " too many to be singly men-
