Palaeozoic series, the instrusive igneous rocks, the Carboniferous Series, 
Post-Carboniferous Changes, the Glacial Period, and the Post-Glacial 
Changes. There is no doubt that this book will be the guide to the geology 
of the district for some time to come. In a pocket at the end is a large 
coloured geological map by H. H. Thomas. There is an excellent index. 
The price seems rather high, but we suppose it’s due to this sanguinary 
war. 
Wild Flowers of the North American Mountains, by Julia W. Henshaw. 
Pp. xvil. and 383, tos. 6d. net. -McBride, Nast & Co., 1916. Mrs. 
Henshaw has written this book in the true spirit of the fiower lover, and 
the region from which she selects her treasures is well adapted to arouse 
one’s enthusiasm. The book is written for the traveller and general reader, 
bnt for the benefit of the botanist there is a general key to the familics. . 
For the convenience of the non-botanical reader the species described in 
the body of the work are classified according to colour. In each genus 
dealt with, one species is usually selected as a type and its character 
described, and the features of the remaining species referred to in popular 
language. English names are added, some of our familiar names being 
apphed to very different American species. Occasionally, as in her 
description of the flower of Parnassia, she goes astray, but on the whole 
the book is very readable, well printed and illustrated with 17 coloured 
and 64 uncoloured plates, most of which are beautifully reproduced. 
Plants in Health and Disease, being an Abstract of a Course of Lectures 
delivered in the University of Manchester during the Session, 1915-16.

Price 1s. 6d. In order to assist the gardeners and cultivators in the 
Manchester district to increase the productiveness of their holdings during 
the present crisis, a series of lectures was arranged and undertaken by 
the botanical and entomological staff of the Manchester University. 
Such was the success of this very laudable attempt to bring the acquired 
store of expert knowledge possessed by a great university down to the 
level of scientifically untrained minds, that it was decided to issue to each 
member of the various audiences a more permanent record in the form 
of short eight-page summaries. The present volume consists of a complete 
set of these. Lectures 1 to 7 deal with plants in health, 7.e., the general 
physiology of plant life, nutrition, vegetative and sexual reproduction, 
hy bridity, etc. This series was undertaken by F. E. Weiss, D.Sc., 
Harrison Professor of Botany. The remaining lectures treat mainly upon 
plants in disease. In lectures 8 to 12, Wilfrid Robinson, M.Sc., Lecturer 
in Economic Botany, describes the chief fungal diseases of plants, their 
life histories and methods of prevention, and includes the results of recent 
research work on some of the chief pests. The remaining of the seventeen 
tectures are concerned with injurious and beneficial animals, and were 
prepared by A, D. Imms, M.A., D.Sc., Reader in Agricultural Entomology. 
The work has certainly interest and value for a wider area than that for 
which it was specially produced, especially as it is well printed, arranged 
and indexed. It is, however, rather a pity that at least some of the 
diagrams, whereby the lectures were originally illustrated, could not have 
been reproduced. 
Lincolnshire. By J.C. Cox, LL.D. (Methuen’s Little Guides Series. pp. 
354, 1916, 2/6)... One is scrry to have to animadvert somewhat severely 
upon a w ork looked forward to with great hopes; but this attempt will 
not do, in no-way supplant Murray’s Handbook of 1896; and is in many 
ways worse than up-to-date:; With the Natural history section (pp.12-18) 
only The Naturalist is, of course, concerned ; but if we are to judge of the 
rest by it, confusion is indeed confounded. ‘Acknowledgements are made 
(p. vil. vill.) to Mr. Jeans (author of the Murray), and Dr. Sympson, and 
others, but help in other departments has apparently not been sought in 
the right quarters. Inaccurate and antiquated indeed, is the account
