PREFACE 



In this work special attention is given to diseases and 

 conditions which are unnamed, atypical, or of infrequent 

 occurrence. It is such conditions that are troublesome 

 and difficult both of diagnosis and treatment. 



The discussions herein are entirely from the viewpoint 

 of the general practitioner ; diagnosis and treatment are 

 emphasized, while aU quibbling over super-scientific de- 

 tails are ignored. 



All conditions and diseases, as well as their treatments, 

 are considered wholly from an American standpoint. 

 Such diseases as occur only in foreign countries are not 

 considered. 



Diseases of very common occurrence, such as the prac- 

 titioner handles almost daily, are also omitted. 



The volume is intended to serve the busy practitioner 

 chiefly as a reference work for diseases and conditions 

 with which, because of their infrequent occurrence, he 

 is not familiar, as well as an aid in the diagnosis and 

 treatment of other more common, yet troublesome, 

 diseases.
