2i8 PATHOGENIC BACTERIA. 



The liver, spleen, and kidneys appear full of tubercles y 

 but careful examination will satisfy the observer that 

 the tubercles are only upon the peritoneal surfaces, not 

 in the organs. 



Intravenous introduction of the cultures produces a 

 condition much resembling general miliary tuberculosis. 

 All the organs contain the pseudo-tubercles in consider- 

 able numbers.
