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 pneumonie’’ 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 ‘‘ 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
