nally proposed by Mr. Berkeley but relinquished by that eminent 

 algologist as " frustrated by Kiitzing's genus Sirosyphon," which 

 Mr. Hassall remarks (p. 231), " I cannot think it is." 



We have not S2)ace to allow of our noticing Mr. Hassall's peculiar 

 views upon the cytoblast and its uses as a " laboratory or stomach 

 in which the materials necessary for the growth and vitality of the 

 cell and its contents are received and digested " (p. 5), or as an or- 

 gan of fertilization (p. 6), or on the " vegetable structure which se- 

 cretes the raphides ;" but this is of less consequence, as they have 

 been remarked upon in rather strong terms of reprobation in the 

 'Botan. Zeitung ' for Aug. 25, 1843 ; that reviewer considers them 

 to be made up of " phantasies and absurdities." 



In conclusion, we would again remind our readers, that although 

 we have found much to censure, that in a much greater number of 

 instances praise is due. It is unfortunately our duty to point out the 

 errors rather than the beauties of such a work as the present, which 

 with all its faults is an acquisition to the British botanist. 



British Libellulinse or Dragon-flies. By W. F. Evans, M.E.S. 

 8,vo. London, 1845. 



A little book containing characteristic figures of all the known 

 British species of Libellulm, but devoid of that artistical beauty to 

 which we are accustomed in entomological works. The figures seem 

 sufficient by which to identify the species and are apparently very 

 accurate. The letter-press is very little more than an explanation of 

 the plates, not containing the generic and specific characters — a very 

 great omission. Neither do we see any reference to the labours of 

 M. Selys de Longchamps in this tribe of insects. 



A Flora of Tunhridge Wells, being a List of Indigenous Plants within 

 a radius of fifteen miles around that place. By Edw. Jenner, A.L.S. 

 Svo. Tunbridge Wells, 1845. 



The most perfect local flora that we have seen, if we take that term 

 as describing a mere list of plants. It is very full in the department 

 of flowering plants, but pecuharly so in that of the cryptogamic tribes. 

 Mr. Jenner's well-known acquaintance with those obscurer tribes had 

 led us to expect a very valuable list, and we have not been disap- 

 pointed. 



Circumstances over which the author had no control have de- 

 layed the publication of this volume so as to make some of the 

 earlier pages appear rather obsolete ; this will not however be found 

 so much the case as to affect the convenient use of the book, which 

 we can strongly recommend.
