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 account. In 

 the "University of Chicago Science 

 Series."
