PKEFACE 



The work concludes with Victory Its Re- 

 ward the great hope of final conquest and its in- 

 finite value to mankind. 



So-called doctors' books are usually, if not al- 

 ways, written by doctors, exclusively in the inter- 

 ests of their profession. This book is written by a 

 layman, exclusively in the interests of laymen. 



Evidently the need for some such work, at the 

 present time, is wide-spread and strikes deep. The 

 fact that one-seventh of the human race die of a 

 single disease caused by a single invisible foe, is 

 wonderful. The fact that this disease is yet, with 

 the right intelligence, easily preventable, as well 

 as all other contagious and infectious diseases, 

 is, if possible, still more wonderful. It shows how 

 deep the want of the right intelligence among the 

 people generally. 



That this book may do something to turn on the 

 searchlight is the hope of 



THE AUTHOR.
