Dr. Morgan seeks to prove that a belief in purpose as the causal reality of which

 of the explanations of naturalism.

This volume has been designed to meet the demand of the constantly increasing 

 number of students for a work presenting in compact form the essential facts so far 

 made known by scientific investigation in regard to the different phases of this, as is 

 now conceded, important and highly interesting subject. While aiming to keep 

 within reasonable bounds, that it may be used for work in the field and in the labora- 

 tory, no portion of the work has been slighted, or fundamental information omitted, 

 in the endeavor to carry this plan into effect.

 the mind, which advances, in the last twenty-five years, have been quite as striking 

 and epoch-making as the strides made in the more material lines of knowledge." —

 in Physical Chemistry in the University of Glasgow. Third Edi- 

 tion, rewritten, with data brought down to 1912. 8°. With 33 

 Diagrams and Illustrations. $2.00 net. 



As the application of the present-day interpretation of Radium (that it is an 

 element undergoing spontaneous disintegration) is not confined to the physical 

 sciences, but has a wide and general bearing upon our whole outlook on Nature, Mr. 

 Soddy has presented the subject in non-technical language, so that the ideas involved 

 are within reach of the lay reader. No effort has been spared to get to the root of 

 the matter and to secure accuracy, so that the book should prove serviceable to other 

 fields of science and investigation, as well as to the general public.

Signora Guglielmo Ferrero's resume 1 of her father's work on criminal anthropo- 

 logy is specially dedicated to all^those whose office it is to correct, reform, and punish 

 the criminal, with a view to diminishing the injury caused to society by his anti-social 

 acts* also to superintendents, teachers, and those engaged in rescuing orphans and 

 children of vicious habits, as a guide in checking the development of evil germs and 

 eliminating incorrigible subjects whose example is a source of corruption to others.

 Economy in Columbia University. 8vo. $1.75 net. 

 A study that is far from being of merely local interest and application. The 



problem is considered in all its aspects and, for this purpose, reference has been made 



to conditions prevailing in other communities and to the different attempts foreign 



cities have made to regulate vice.
