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 space 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 Libellulinze or Dragon-flies. By W. F. Evans, M.E.S. 
8vo. London, 1845. 
A little book containing characteristic figures of all the known 
British species of Libellule, 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 Tunbridge Wells, being a List of Indigenous Plants within 
a radius of fifteen miles around that place. By Edw. Jenner, A.L.S. 
8vo. 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 peculiarly 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.
