mentof glaciers, he does not seem to have accepted Forbes’s doctrine. 
His remarks on the various forms of stratification, and on their modifica- 
tion by internal and external influences, deserve perusal. We see for the 
first time the late Professor Kinahan’s sketches of Oldhamia and Histio- 
derina reproduced ; and from experience, can testify to their being capital 
representations of these peculiar Cambrian fossils. The palaeontological 
division of the volume has been handled in as masterly a manner as the 
other, and both are adorned with hosts of well-executed woodcuts. We 
heartily wish Mr. Jukes’s “ Manual ” every success. 
LOCAL FLORAS.* 
W E can never expect to get a thoroughly systematic “British Flora” 
till we possess accurate lists of the plants in each county, and 
properly drawn lines indicating their superficial and bathymetrical dis- 
tribution. In the two volumes lying on our table a very laudable endea- 
vour has been made to furnish the public with scientific catalogues of the 
plants found in Surrey and Marlborough. That which relates to the 
former county is the better of the two, but each is remarkably good of its 
kind. The “ Flora of Surrey,” we are informed, has been prepared from the 
manuscripts of the late J. D. Salmon, F.L.S., under the auspices of the 
Holmesdale Natural History Club. It is exceedingly systematic ; and were 
it not that its compilers have given admitted [varieties the rank of true 
species, we should have little to complain of. The tendency of present 
botanists- — of that school at whose head Bentham stands — is to reduce the 
number of so-called species very considerably. And we do not think we 
are going beyond the mark when we say, that the Surrey flora, as repre- 
sented by Mr. Brewer, contains a hundred more species than the county 
possesses; in other words, five score of Mr. Brewer’s species are mere 
varieties. Perhaps the best portion of the work, like the essence of a lady’s 
letter, is to be found in the appendix. This contains a tabular arrange- 
ment of the plants, showing their geological distribution, which is further 
indicated on a beautiful geological map attached to the volume, and pre- 
pared expressly for it by Mr. Prestwich. It is, on the whole, a book 
which must prove very acceptable to all London botanists. The “ Flora 
of Marlborough,” which includes a list of local birds, is a far less preten- 
tious volume, and, as its author states, was prepared for the members of 
the College, in order to induce them to take an interest in botanical 
science. Nevertheless, it has been well and creditably executed ; and, from 
the author’s modest expression of doubt as to its accuracy in some parti- 
culars, it is evident that he is a cautious and industrious botanist, and one 
well adapted for the labour he has undertaken. True science is almost 
always sceptical.
