HOW ANTITOXIN SAVED LIVES 



The records of a large metropolitan hospital in London showed the number of deaths 

 in each hundred cases of diphtheria for five years before and five years after anti- 

 toxin came into use 



presence of the disease can be recognized. The antitoxin is then without 

 effect. Tetanus antitoxin is a dependable preventive, but the disease is too 

 rare to vi^arrant routine inoculations. Doctors use it wherever a wound may 

 have become infected with the tetanus organism. 



What Kinds of Anti Bodies Do Organisms Produce? 



Protoplasm Strikes Back We cannot measure humanity's gains from 

 Jenner's work in preventing smallpox, or from Behring's work a century 

 later in curing diphtheria. We can say that two very important sources of 

 mankind's miseries have been wiped out completely in many regions, and 

 are being pushed farther back as fast as people make use of our knowledge.
