 Application of the Theory of | Electrolytic Dissociation | and the Law 

 of Mass Action | by | E. H. S. Bailey, Ph. D. | professor of chemistry 

 in the University of Kansas | and | Hamilton P. Cady, Ph. D. | pro- 

 fessor of chemistry in the University of Kansas | Eighth Edition | 

 revised by | Paul V. Faragher, Ph. D. | assistant professor of chemistry 

 in the University of Kansas | in collaboration with the authors |

 right, 1916. Cloth pp. i-x+ 1-294. Price $1.50. 



The eighth edition of Professors Bailey and Cady's book, re- 

 vised by Assistant Professor Faragher, is essentially the same as 

 the seventh edition except for some minor modifications, con- 

 sisting in the amplification of some sections difficult of com- 

 prehension by the student. 



The scope and volume of this edition is, in general, the same 

 as that of previous editions. The introductory part covers 24 

 pages ; 126 pages are devoted to the reactions of the cations and 

 a table for their systematic analysis, and 117 are taken up with 

 the anions, also with a table for their systematic analysis. None 

 of the rare metals are treated, except gold and platinum. A 

 table for use in the examination of an unknown substance and 

 another table of solubilities close the text. 



The introductory portion is furnished with a brief and accu- 

 rate discussion of electrolytic dissociation and the mass action 

 law as it is applied to qualitative analysis. The experiments 

 given for the reactions of the individual ions are well selected; 

 the tables for the separation of cations and anions into groups 

 and the tests for their identification includes some good tests, 

 for example, the dimethyl glyoxime reaction with nickel ions; 

 while such subjects as hydrolysis, oxidation, and reduction are 

 treated clearly in proper places in the book, thus rendering it 

 easy for the student to comprehend their practical application. 



The mechanical details of the book are good and misprints 

 are few (p. 68, 4H 4 instead of 4H 2 0). The type is clear, and 

 the illustrated tables are well gotten up. 



On the whole, the book is a good, brief laboratory guide for 

 students in qualitative analysis.
