BIBLIOGRAPHICAL NOTICES. 



The Tourisfs Flora : a descriptive Catalogue of the Flowering Plants 

 and Ferns of the British Islands, France, Germany, Switzerland, 

 Italy, and the Italian Islands. By Joseph Woods, F.A.S., 

 F.L.S., F.G.S. Reeves, London. 8vo. Pp. Ixxxii. 505. 



The appearance of this book has been long expected by us, and 

 we can justly state that it has quite fulfilled all our expectations and 

 well supports the high reputation of its author. 



Mr. Woods is known to have spent many years in collecting and 

 arranging the materials for the present work, with a view to which he 

 has, we believe, visited all the m6re interesting localities mentioned 

 in it. This amount of labour, combined with extensive botanical 

 knowledge, has enabled him to produce a volume such as few if any 

 other botanists were capable of writing. 



" The intention of the present work is to enable the lover of botany 

 to determine the names of any wild plants he may meet with, when 

 journeying in the British Islands, France, Germany, Switzerland, and 

 Italy," thus including in one book the plants of a far larger part of 

 Europe than has been done by any preceding author ; for Reichen- 

 bach's * Flora Excursoria* omits Britain, France, and the greater 

 part of Italy, but includes Hungary ; and we are not acquainted with 

 any other work of similar scope. 



" To accomplish this object, I had," says the author, " to keep in 

 view two important particulars, — to make the descriptions clear and 

 distinctive, and at the same time to condense the whole as much as 

 possible, so that the work might be comprised in a single volume, of 

 a bulk not inconvenient for the use of the traveller." In both these 

 objects he seems to have been pretty successful ; although we do not 

 always find the " difiference at least sufficient to discriminate the plant 

 from all the others contained in this work," to which he refers ; yet 

 in most cases it is well pointed out. The system of condensation 

 appears, as far as the author was concerned, to have been carried to 

 its extreme limits, but he has not been well seconded by his printer. 

 We suspect a wish was present, perhaps unknowingly, to the printer
