lymphatic glands and lymphangitis are also, we believe, more 

 frequently caused by streptococci than staphylococci. They also 

 produce fibrinous exudation on the mucous surfaces, leading 



to the formation of false 

 membrane in many of the 

 cases of non-diphtheritic 

 inflammation of the 

 throat, which are met 

 with in scarlatina 1 and 

 other conditions, and they 

 are also the organisms 

 most frequently present 

 in acute catarrhal inflam- 

 mations in this situation. 

 In puerperal peritonitis 

 they are frequently found 

 in a condition of purity, 

 and they also appear to 

 be the most frequent 

 cause of puerperal septi- 

 caemia, in which condition 

 they may be found after 



death in the capillaries of various organs. In pyaemia they are 

 frequently present, though in most cases associated with other 

 pyogenic organisms. Some cases of enteritis in infants 

 streptococcus enteritis are also ' apparently due to a strepto- 

 coccus, which, however, presents in cultures certain points of 

 difference from the streptococcus pyogenes. 



The bacillus coli communis is found in a great many inflam- 

 matory and suppurative conditions in connection with the ali- 

 mentary tract for example, in suppuration in the peritoneum, 

 or in the extra peritoneal tissue with or without perforation of the 

 bowel, in the peritonitis following strangulation of the bowel, in 

 appendicitis and the lesions following it, in suppuration in and 

 around the bile ducts, etc. It may ateo occur in lesions in other 

 parts of the body, endocarditis, pleurisy, etc., which in some 

 cases are associated with lesions of the intestine, though in others 

 such cannot be found. It is also frequently present in inflamma- 

 tion of the urinary passages, cystitis, pyelitis, abscesses in the 

 kidneys, etc., these lesions being in fact most frequently caused 

 by this or closely allied organisms. 



In certain cases of enteritis it is probably the causal agent, 



1 True diphtheria may also occasionally be associated with this diseases 

 usually as a sequel.
