larly consolidated. There was bronchial breathing and 
harsh and dry rales. The heart was enlarged, but other- 
wise normal. 
The leucocyte count was seventeen thousand. The pa- 
tient died, ten days after admission, about twelve weeks 
after the onset of the disease. The autopsy showed acute 
bronchia] pneumonia, abscesses of the retro-peritoneal 
lymph glands, and encapsulated empyema, enlarged and 
softened spleen, with colloid swelling of the liver and 
kidneys. In all the diseased parts that were examined 
_ there were found peculiar parasitic organisms, which in 
the few recorded cases, have been described as protozoa. 
The life history of these parasites shows the youngest 
forms as small, spherical masses of protoplasm enveloped 
ina membrane. The protoplasm is granular, stains well 
and is occasionally vacuolated. The organism sometimes 
attains a diameter of thirty micromillimeters and is all- 
ways perfectly spherical. 
When the adult stage is reached, the capsule breaks, 
and one hundred or more spore-like bodies are detached. 
Locomotion was never observed in the adult forms, nor 
in the spores. The close resemblance of these spores to 
coccidia, led to their classification as protozoa. 
The lesions produced by their presence in the human 
body, are chronic suppurating processes. The organism 
grown upon agar-agar, showed mycelia. Inoculated into 
guinea pigs, it caused suppurating foci, and the same 
mould was recovered as had been noted in the patient. 
The organism was found to develop mycelia, when free 
in a culture medium such as a hanging drop of bouillon,
