Grawitz's Theory. A theory as to the immunity con- 

 ferred by inoculation. The cells of the body and the 

 bacteria take their nutrition from the same places, and 

 it is a true fight for existence between them. If the 

 cells come out victorious, they become habituated to 

 the struggle with the bacteria, and are more able to 

 resist a second attack, and this quality is transmitted 

 to the succeeding generations of body-cells by heredity. 

 This theory is purely hypothetic.

 meanwhile continued. As a result, a pomade > !
