[Ready in April]This i s an indispensable work of reference for chemists and for all whowish to know the meaning of chemical terms and facts about well-knownchemical substances and drugs. It contains biographical notes on manypast and living chemists and articles which give the most up-to-dateinformation about chemical theories and problems of the day as well asthe recent developments in Biochemistry and Chemical Engineering.Sofar as we know, there i s no other work in existence which contains ina handy form so much accurate information about the modern conceptionsof theoretical and physical chemistry, about inorganic and organicchemistry and biochemistry. An important point i s that the informationi s up to date, i.e., to the year 1939.A TEXT-BOOK OF QUANTITATIVEINORGANIC ANALYSIS:Theory and Practice.By ARTHUR 1.

There i s no doubt that this book will be widelyadopted as a text book in English speaking Colleges and Universitiesthroughout ths world.”-journaf of the institute of Chemistry.iTHE INSTITUTE OF CHEMISTRYOF GREAT BRITAIN AND IRELANDThe Institute of Chemistry was established in 1877 to providethe Government and the public with the means of recognis-ing those who have been properly trained and proved to becompetent to practise chemistry as a profession. In 1885 theInstitute was granted a Royal Charter with authority to grantcertificates of competency, and to register persons qualifiedto practise.The aims of the Institute include the elevationof the profession of chemistry and the maintenance of theefficiency, integrity and usefulness of persons practising thesame, by compelling the observance of strict rules ofmembership, and by setting up a high standard of scientificand practical efficiency.Particulars of the Regulations and Examinations of theInstitute can be obtained (free) on application.All communications to be addressed to the RPgisirar,THE INSTITUTE OF CHEMISTRY30 Russell Square, W.C.1C H E M I C A L S O C I E T YMEMORIAL LECTURES(Suitable for presen f a fion as school prizes)VOLUME I, 1893-1900.
