show an increased resistance toward a second infection. The resistance ob- 

 tained with immune sera lasts, however, only for a period of 2 weelvs and cor- 

 responds in this respect to the antitoxic sera. An active immunity was not ob- 

 tained, and it is assumed that this is due to the sti-ong action exerted by the 

 immune serum upon the bacteria, mailing it impossible for the bacteria to mul- 

 tiply, even locally. 



The author concludes that simultaneous vaccination is only efficient when 

 the bacteria used for infection can provoke a stimulation upon the organism.
