-MALAXIS PALUDOSA L. IN CHESHIRE. 
ARTHUR BENNETT, 
Croydon. 
In the ‘ Flora of Cheshire’ (1899) p. 304, there is a note that 
“The late Mr. W. Wilson has entered ‘“ Cheshire’”’ opposite to 
this plant in his copy of Watson’s “ Outlines,’’* now belonging 
to Mr. B. D. Jackson. It is most likely he was mistaken in 
the boundary of our county, and gathered it on Yorkshire 
ground.’ 
But there is no doubt he knew where it had been found 
as shown by Mr. Cash’s interesting account of Mr. Wilson.f 
“In July, 1831, he visited a place called Sinks Moss, near 
Knutsford, in order to gather MWalaxis paludosa, but returned 
home unsuccessful. The place was partly enclosed and 
cultivated.’ This extract answers the query.

South African Geology, by Prof. E. H. L. Schwarz. London: Blackie 
& Son, 200 pp. 3s. 6d. net.—Professor Schwarz’s work on the geology 
of South Africa is well known, and we are glad that he has brought 
together a concise summary of the main geological features of that inter- 
esting area. From both scientific and economical points of view a keen 
interest is being taken in the geology of our flourishing colony, conse- 
quently there will no doubt be a good demand for this book. It is well 
arranged, well written, and well illustrated. 
Cryst llography and Practical Crystal Measurement, by A. E. H. Tutton, 
D.Sc., M.A., F.R.S., etc., pp. xiv. + 946 (London: Macmillan & Co., 
Ltd., 1911. Price 30s. net). So great are the strides that have been 
taken by the science of crystallography during recent years that such a 
book- as the present has become a crying necessity. The setting-forth 
of the latest discoveries in this science could not have been placed in 
more capable hands than those of Dr. Tutton, whose brilliant researches 
in a field of work he has made peculiarly his own are of world-wide fame. 
In addition to being a clear exposition of the theoretical portion of the 
subject, most of which can be read with interest and profit by the layman, 
the book is essentially practical, enabling the student by its aid to carry 
out for himself the examination of crystals and their forms. It is difficult 
to say to whom the book will be of greatest service—to the chemist, 
physicist, or mineralogist—but it can safely be said that it is essential 
to each. The book is well arranged and contains 720 illustrations, and 
is got up in the thorough manner characteristic of the text-books issued 
by Messrs. Macmillan & Co. Some books on crystallography are for- 
bidding, but this work is not so. The author is obviously enthusiastic 
over his subject, and the book has thereby that appealing human interest 
that is as essential to the success of scientific memoirs as to works of a 
lighter nature. With the author we believe that there zs a great future 
before this subject, we feel confident that the book will ‘ help forward the 
progress of crystallography,’ and we trust as a result of his labours there 
may be attracted to this important subject ‘ an increasing number of 
earnest spirits seeking for a field of tascinating and richly rewarding 
research) —— B.A
