AX interval o£ three years has elapsed since the publication of 

 Vol. I. of this monumental work, and we now welcome the 

 appearance of Part 1 of Vol. IT., which deals in a very exhaustive 

 manner with the equilibrium between the solid, liquid, and gaseous 

 phases of such binary systems as contain only the two components 

 in the solid phase, the case of compounds or mixed crystals being 

 reserved for future treatment in the second part of Vol. II. 



After a brief general introduction, the author begins with the 

 study of the equilibrium between a liquid and a gaseous phase. A 

 characteristic feature of the author's method of treatment is the 

 free use made of graphical representations and models in three 

 dimensions. In such a solid construction, the three coordinate 

 axes are taken to represent the percentage composition of a variable 

 phase, the pressure, and the temperature. The use of the solid 

 model is carefully explained in the section specially devoted to this 

 subject. Then follows a detailed study of various special cases, 

 including the equilibrium, under constant pressure, of one com- 

 ponent having solid and liquid phases, and of two solid components 

 with or without a liquid phase. The various experimental methods 

 for determining the solidification curves are explained, and nume- 

 rous examples are given in illustration of the general theory. The 

 next section deals with phase complexes under variable pressure, 

 and in the concluding section are considered binary systems in 

 which the components exhibit polymorphism. 



The compilation of the present volume must have involved an 

 immense amount of care and thought ; it embodies the views of 

 one of the most eminent authorities on the subject, and must be 

 regarded as one of the most valuable recent contributions to the 

 rapidly-growing literature of physical chemistry.
