Society has permitted us to reproduce. Other plantsexamined and 
figured are Bluebell (Scz//z), Hair Grass (Deschampsia flexuosa), 
Yorkshire Fog (Holcus mollis), Hogweed (Heracleum), Dog’s 
Mercury (Mercurialis perennts), and Yellow Dead Nettle 
(Lamtum Galeobdolon). These figures indicate that while most 
species of plants occur in definite plant associations, and are 
limited to certain conditions of erial and soil conditions, 
they have considerable powers of adaptation to change of en- 
vironment. This fact cannot be lost sight of in ecological 
botany, and the details shown by Dr. Woodhead emphasise 
the importance of careful examination. 
The bibliography appended to this paper is a long one, and 
is well worth careful perusal, if only to gather some idea of the 
complex nature of these ecological studies. 
The paper as a whole is an excellent example of the results 
which may be expected from careful ecological survey, although 
the author himself states that much still remains to be investi- 
gated regarding the relation of plants to their environment. 
Under the guidance of the painstaking and careful author of 
this paper, these more exact studies are in progress, and the 
results will be looked for with keen interest.—W. G. S. 
The Science Year Book: Diary, Directory, and Scientific Summary. 
King, Sell, and Olding. Price 5/- net. 
This indespensable volume increases in usefulness each year. No 
working scientific man can afford to be without it. The present issue 
has many improvements. To astronomers particularly is it invaluable, 
and contains much information. There is a review of ‘Science in 
1906,’ in which the more important discoveries, etc., are enumerated; a 
useful but apalling glossary of scientific terms that have been recently 
introduced; a directory of Periodicals, Public Institutions, Societies, 
Universities, etc.; a Biographical Directory, and a daily diary. As a 
frontispiece is a portrait of Lord Rayleigh. An abridged edition, without 
the diary, but containing all the articles, is on sale at 3/-.

This is a companion to ‘The Romance of Plant Life,’ noticed in these 
columns for December last. It is a substantial book, and has a gaily coloured 
cover. This volume, too, is for the young naturalist, and contains much 
interesting information. The fact that it is a ‘Romance’ prevents criticism 
so far as scientific accuracy is concerned. The sub-title perhaps explains 
its scope ‘being an interesting [!] account of the spinning, weaving, 
sewing, manufacture of paper and pottery, aéronautics, raft-building, road- 
making, and various other industries of wild life.’ The animals are classified 
according to whether they are ‘excavators and miners,’ ‘makers of mounds,’ 
‘masons,’ ‘carpenters,’ ‘ trappers,’ ‘harvesters,’ etc., etc. ; and the authors 
have been able to gather together quite a wonderful series of stories which 
should not fail to instruct the individual who is so handsomely catered for 
now-a-days—‘ the young naturalist.’ The book is cheap, and is indexed.
