It aims to give an account of the origin and significance of tlie later developments in Physical Chemistry. 

 The origin and development of the theory of electrolytic dissociation are followed by an examination of the im- 

 portant lines of evidence bearing on the theory, and by a few applications of it in chemistry, physios and biology.
