English version by ALEXANDER SMITH 
Associate Professor of Chemistry in the University of Chicago 
SERIES of eight lectures on the application of 
physical chemistry to the elucidation of prob- 
lems in the sciences of pure chemistry, industrial 
chemistry, physiology, and geology. The lectures 
deal largely with discoveries which have been made 
in Professor van ’t Hoff’s laboratory or by his former 
students, and are preceded by an introductory lecture 
upon the fundamental principles of physical chemis- 
try. The addresses are somewhat popular in char- 
acter, and the text is copiously illustrated with cuts. 
A portrait of Professor van 't Hoff is inserted as 4 
frontispiece.
