The 

 Antiquity of Disease 



By ROY L. MOODIE 



From the examination of fossil vertebrates 

 and the bones of early man, Professor 

 Moodie has constructed a remarkable pic- 

 ture of prehistoric pathological conditions. 

 The relation of such evidence to the 

 origin and evolution of disease is pre- 

 sented in a readable, non-technical fash- 

 ion, and the text is interspersed with 

 especially prepared illustrations. The 

 wisdom gained from medical history, gen- 

 eral evolution, zoology, and geology is 

 focused on this study, and the result is 

 an exceedingly informative accoimt. In 

 the "University of Chicago Science 

 Series."

The Geography of Illinois 



By DOUGLAS C. RIDGLEY 



Professor of Geography in the Illinois State Normal University 



The author's aim is to provide an authoritative study of the state, presenting in 

 compact form the wide range of physical influences which make up the geographic 

 environment in which men live. 



The natural features and natural resources of the state are treated in some detail. 

 The great occupations of mankind— agriculture, mining, manufacturing, trans- 

 portation, and trade— are discussed with sufficient fulness to give an adequate 

 idea of their development and present importance within the state. The popula- 

 tion census of 1920 for Illinois is treated in a final chapter. The book is designed 

 to be of mterest to the busy citizen who wishes to know his state as a unit in its 

 present-day activities; to teachers and pupils who would know Illinois well enough 

 to interpret other regions in comparison with the home state; to all who wish to 

 learn the reasons for the high rank of Illinois in many lines of human endeavor. 



Abounds with drawings, maps, illustrations, and colored insert maps
