SCIENCE A 
“ INDUSTRIAL CHEMISTRY.” 
A SERIES OF MONOGRAPHS, Edited by Samuel Rideal, D.Se., FEC. 
(London: Bailliere Tindall & Cox, 1918.) 
One great result of the war has been the revolutionary changes in all branches 
of Technology, brought about by the rapid developments in applied chemistry, 
engineering, sanitation, aeronautics, &e. The present series of monographs 
aims at giving a general survey of applied chemistry treated from the chemical 
rather than from the engineering stand-point. Each volume is complete in 
itself, and is divided into sections, each of which is also a complete article on 
the subject it contains. A selected bibliography is attached to each section, and 
a general bibliography of the whole industry is provided, which, it is hoped, will 
serve as a guide to the standard literature of the whole subject. 
Present tendencies and possible future developments are indicated. The 
volumes are written by specialists connected with the various industries, who 
thus supply the link which has been so much praised in Germany’s industrial 
organization. 
The Editor establishes a difficult ideal to be realized when be endeavours, at 
one and the same time, to cater for the needs of— 
1. The man of affairs having no special technical knowledge; 4 
2. The advanced student whose mind, crammed with chemical facts, is 
unable to realize the industry as a whole; and 
3. Those actually engaged in the industry who have specialized in_ rather 
narrow limits, and who desire a little more knowledge of their 
subject generally. 
Messrs. Angus and Robertson, Sydney, have supplied copies of five volumes 
already issued, viz.:— 
(1) The Alkali Industry, by J. R. Partington, M.Se., Assistant in the 
Chemical Department, University of Manchester. (Pp. XVI. + 304, 
with 63 text figures. February, 1918.) 
(2) Coal Tar Dyes and Intermediates, by K. de Barry Barnett, B.Se. 
(London), A.C. (Pp. XVIII. + 218. January, 1919.) 
(3) Dyeing with Coal Tar Dyestuff, by C. M. Whittaker, B.Se. (Pp. 
XII. + 214. June, 1918.) 
(4) Industrial Electro-Metallurgy, including Electrolytic and Electro- 
thermal Processes, by Erie K. Rideal, M.A. (Cant.), PhD, F.C. 
(Pp. XII + 247. June, 1918.) 
(5) Plant. Products and Chemical Fertilizers, by S. Hoare Collins, M.Sc. 
F.LC. (Pp. XVI. + 236. February, 1918.) 
(1) Probably the first thing that strikes one’s attention is the inclusion of 
sulphuric and nitric acid and chlorine in the alkali industry. These together 
oceupy nearly one-third of the book, with the result that other subjects become 
crowded out. The relative amounts of space appear to have been irregularly 
allotted. One idea of treating chemistry and other science subjects in compact, 
monographie series, is that the volumes can be kept up-to-date better than a 
large text book, and that small books are much more conyenient to handle. 
We hope to see in the future more space devoted to electrolytic processes (8 
pages), bleaching powder (4 pages), magnesium and its salts (2 pages), and 
some other sources of potash, which vitally concern agriculture throughout the
