MICROCOCCUS LANCEOLATUS. 509 



the subject this micrococcus was present in 27. Monti 

 demonstrated the presence of the same micrococcus in 

 4 cases of cerebro-spinal meningitis. Weichselbaum, 

 in a series of 29 cases of ulcerative endocarditis exam- 

 ined, found <( diplococcus pneumoniae" in 7. It has 

 been found also in acute abscesses in the pus of paro- 

 titis complicating pneumonia it was obtained in pure 

 culture by Testi; in a case of pneumonia, in which 

 there developed a purulent pleuritis and parotitis, and 

 multiple subcutaneous abscesses, it was found in great 

 numbers in all these places in the pus; in a case of 

 tonsillitis resulting in the formation of an abscess it 

 was obtained in pure culture by Gabbi. This micro- 

 coccus has also been found in a number of cases of 

 otitis media in the pus obtained by paracentesis of 

 the tympanic membrane, by Netter in 5 out of 18 cases 

 occurring in children. Monti and Belfanti report cases 

 of arthritis of the wrist-joint, occurring as a complica- 

 tion of pneumonia, in which it was found. Ortmann 

 and Samter, in a case of purulent inflammation of the 

 shoulder-joint following pneumonia and pleurisy, ob- 

 tained the u pneumococcus " in pure culture. It has 

 been found in other cases of inflammation of the knee, 

 ankle, and elbow-joints, and in osteomyelitis and perios- 

 titis. In short, there is scarcely any part of the body 

 in which this organism may not find suitable conditions 

 for existence and in which it does not sometimes occur. 

 How is it conveyed from its original seat in the lungs 

 to distant internal organs? Chiefly by means of the 

 bloodvessels and lymphatics, in both of which it has 

 been found in great numbers. Proof enough of its 

 conveyance through the lymphatics is afforded by the 

 frequent occurrence of inflammations of the serous
