Rhus Dermatitis 



Its Pathology and Chemotherapy 



By JAMES B. McNAIR 



^ The lack of any rational treatment for 

 the common infection resulting from 

 poison oak or poison ivy has suggested 

 a, protracted study of the isolated prin- 

 ciple, in the hope that knowledge of its 

 characteristic properties may serve as a 

 basis for such treatment. 



^ Complete analysis of cause, effect, and 

 remedy has been attained by investi- 

 gating from the three distinct standpoints 

 of pharmacology, botany, and chemistry.

Source Book for the Economic 

 Geography of North America I 



By CHARLES C. COLBY 



Associate Professor of Geography 

 in the University of Chicago 



The fundamental idea of this book i? to make available to the busy teacher th< 

 material on this subject which is scattered widely through literature. The course whic| 

 has been given for a number of years at the University of Chicago has resulted in tl 

 collection and organization of the material most suitable for the purpose. 



The book contains short magazine articles and materials from Canadian, Mexicar 

 and United States government publications. The selection of the material has beec 

 governed by the concept that there is a direct relation between the environment and 

 the economic activities of the region. The author aims to survey the different sections 

 of the country from the viewpoint of industrial opportunity.
