The Forests of India, by E. P. Stebbing. London : John Lane, 
The Bodley Head, xv‘. +548 pp., 42s. net. Professor Stebbing has had 
considerable experience in connection with Forestry in India, having 
been for many years in the Indian Forestry Service. This practical 
knowledge, together with exceptional ability to present that knowledge 
in an entertaining fashion, results in this substantial book of 550 closely 
printed pages being especially readable. There can be no question that 
a careful study of the various forest questions in the Indian Empire adds 
considerably to the wealth of that important area. Professor Stebbing 
appears to have made himself familiar with the trees in various parts 
of that great country, and his chapters dealing with this subject must be 
of tremendous value not only to the Government but to all who are 
interested in Forestry in various parts of the world. The author's 
scientific training stands him in good stead and makes his book much 
more reliable than is usually the case. 
Petrographic Methods and Calculations, by Arthur Holmes. 
London : T. Murby & Co., xviii.q-515 pp., 31s. 6d. net. Messrs. 
Murby are specialising in this class of literature and certainly their latest 
production is one of their best. Just now, when so much attention is 
being devoted to the mineralogical constituents of the rocks, the appear- 
ance of this magnificent volume, with its carefully prepared chapters 
dealing with Petrology : Its Scope, Aims, and Applications ; The 
Specific Gravity of Minerals and Rocks ; Separation of Minerals ; Optical 
Examination of Crushed and Detrital Minerals ; Examination of Detrital 
Sediments ; Preparation of Thin Sections ; Microchemical and Staining 
Methods ; Textures and Structures of Igneous and Metamorphic Rocks ; 
Chemical Analysis and their Interpretation ; and Graphical Repre- 
sentation of Chemical Analysis ; is most appropriate. The author is 
well known, and we predict a successful career for the volume. At the 
end are several plates with rock sections and careful descriptions 
thereof. 
The Naturalisation of Animals and Plants in New Zealand, by 
The Hon. G. M. Thomson. Cambridge University Press, 607 pp., 
42s. net. For the first time, with the aid of the house of Macmillan and 
the author, we are in a position to form an idea of the extraordinary 
Flora and Fauna of New Zealand. In this substantial volume the author 
has gathered together a detailed description of the Fauna from the highest 
to the lowest orders, and the Flora is similarly perfect and complete. 
The author’s chapter on the Interaction of Endemic and Introduced 
Faunas is a remarkable contribution to the distribution of animal and 
plant life, albeit that the author considers that the effect of foreign animals 
and plants into the land have been so far-reaching and so complex that 
it is impossible to present any summary of them, and all that can be 
done is to show various aspects of the question and to consider facts in 
detail. The author acknowledges the help of various specialists he has 
consulted, and there is a good Bibliography and an index to the animals 
and plants. 
Vol. I., No. 1, of The Bulletin of the Hill Museum : a Magazine 
of Lepidopterology, by Messrs. J. J. Joicey and G. Talbot (200 
pages, 30/- net) is to hand. We must admit that we received a surprise 
on examining this lavish publication, with its wealth of half-tone illus- 
trations and plates. From the photographs reproduced of the staff at 
the Museum, as well as the Museum itself, it would seem that this par- 
ticular institution is one of an altogether remarkable character. We 
only hope that the sale of this publication will recompense, to some 
extent, the enormous outlay which has obviously been necessary to 
produce it, and that the particular source of income will long be forth- 
coming in order to publish future Bulletins. The Bulletin contains : 
Introduction ; Bibliography of Previous Publications of the Hill 
Museum ; Euploeines Forming Mimetic Groups in the Islands Key, Aru,
