CHEMICAL DISINFECTION AND 

 STERILIZATION. 



By S. RIDEAL, D.Sc., F.I.C., and E. K. RIDEAL, M.A., 



D.Sc., F.I.C. 

 One Volume. Demy 8vo. 2 is. net. 



Owing to the cessation of German imports during the Great 

 War many new Disinfectants were placed on the market which, 

 while being similar to the German articles previously used, 

 appeared under different proprietary names. During this same 

 period, in consequence of military requirements, much research 

 on the use of new substances as disinfectants was carried out, 

 and consequently many new disinfectants came into use. The 

 present time is, therefore, singularly appropriate for the publica- 

 tion of a book on this subject, and the authors have collected a 

 mass of material which is scattered through numerous scientific 

 journals, and have given a connected and comprehensive account 

 of this important branch of scientific knowledge. 



The subject-matter may be divided roughly into three parts : 

 firstly there are chapters dealing with disinfection and steriliza- 

 tion for specific purposes, such as disinfection of public vehicles, 

 preservation of food and sterilization of water; secondly, the 

 disinfectants are described according to their chemical structure 

 and the class of compounds to which they belong ; and, finally, the 

 methods of testing disinfectants are given. As the authors are 

 well-known authorities on disinfection, the Rideal- Walker Test 

 being one of the standard tests adopted in this branch of scientific 

 work, it cannot be doubted that the book will become the 

 standard work on the subject and will have a large circulation 

 amongst those who are concerned in the maintenance of public 

 health.

Dr. Lister's book will prove useful to the many medical men 

 who undertake examinations on behalf of Life Insurance 

 Companies, a part of the work of the general practitioner which 

 involves some variations from ordinary method corresponding 

 with the special object with which such examinations are made.
