connective tissues and in parenchymatous organs is often, if 

 micrococci are present in the original focus, associated with 

 a corresponding spreading of the micrococci ; these easily 

 grow into all the spaces and crevices of the tissues, but 

 whether this spreading of the micrococci is merely of 

 secondary importance, i.e. concomitant with or subsequent 

 to the spreading of the inflammation, or whether it is the 

 primary cause as some assume, is not clear, and requires 

 definite experimental proof.

2. Zooglcea of micrococci. 



In all cases of diarrhoea the secretions of the bowels swarm 

 with micrococci. In typhoid fever, clumps of micrococci 

 may be found very extensively on the ulcerations of the 

 bowels, and in the mucous membrane surrounding the 

 ulcerations, and may be even traced into the mesenteric 

 glands and the spleen. 1 



In dead tissues within the living body, such as occur after 

 embolism, and in the case of various infectious maladies, 

 micrococci may be found in colonies, i.e. as zooglcea,
