Students and physicians will find this book an authoritative 

 work which presents, with clearness and simplicity, the subjects 

 of immunity and the forces of resistance to infectious diseases 

 in the body. Recent developments have shown the great prac- 

 tical importance of these subjects to the student and general 

 practitioner, as well as to the laboratory specialist. The ma- 

 terial dealt with is fundamental to the comprehension of the 

 processes involved in the occurrence and cure of infectious dis- 

 eases, and a thorough study of it is essential as a preparation 

 for the study of infectious diseases in the clinic.
