character. We have mentioned that the plants here investigated 
are those whose internal structure has been preserved, either silici- 
fied or calcified ; and thus it arises that the methods of anatomic 
observation are well adapted to the prosecution of this branch of 
research. 
Where praise is due in no unstinted measure it may seem un- 
gracious to note a small blemish; but the question suggests itself, 
Why should the author continue to write Lyginodendron Oldhamium 
with a capital letter? The form Oldhamium is due to earlier 
writers (instead of the more correct form oldhamense) ; but we find 
other instances, such as Chetrostrobus Pettycurensis, when the same 
author has correctly written Medullosa anglica. These trifling 
departures from the common usage of botanists do not, of course, 
really detract from the usefulness of the book, which, regarded from 
every point of view, is worthy of the author and of his subject. 
First Records of British Flowering Plants. Compiled by Wittram A. 
Cuarke. Second Edition, Revised and Corrected. London: 
West, Newman, & Co., 1900. Pp. xvi, 194. 
Tue first draft of this volume appeared in the ‘ Journal of Botany’ 
for 1892-96, and it was republished as a separate work in 1897, 
with additions and corrections and a note on nomenclature. But 
this edition did not satisfy the author, who has again revised the 
work, added the actual names used by the old authors cited, and 
has brought it out in a form which is a great improvement on the 
last edition. 
The work being thus well known to the majority of British 
botanists, it hardly needs detailed description ; but we may cordially 
welcome its reappearance in its new shape.

On the Dates of Publication of the ‘ Histoire naturelle générale et 
particuliére des Mollusques terrestres et fluviatiles’ and the 
‘ Tableaux systématiques des Animaux mollusques, by the Barons 
Férussac and G. P. Deshayes. By C. Davizs Saerzorn, F.Z.S. &c., 
and B. B. Woopwarp, F.L.S. &e. 
Tur exact dates of publication of the parts of these remarkable 
twin works have long been a source of difficulty for malacologists, 
and though we have not been able to completely solve the problem, 
we think that enough information has been brought together to 
justify publication of the results attained. 
The two works were issued together in 42 livr., which appeared 
between 1819 and 1851, while some portions of the text appear to 
have been issued in early livraisons of the companion work by the 
younger Féruesac and Alcide d’Orbigny—the ‘ Hist. nat..... des
