A New Rhizopod Parasite in Man. — Professor Ijima? has de- 
scribed a new species of Rhizopod, Amæbæe miurai, parasitic on the 
human being. The patient in whom these parasites were found 
was a young woman suffering from abdominal tumors and an ascites- 
like accumulation of fluid in the abdominal cavity. She finally died 
of peritonitis and pleuritis endotheliomatosa. The amcebe were found 
in abundance in the fluids of the peritoneal and pleural cavities as 
well as in the hemorrhagic discharges from the intestine. As many 
of the amcebzx in the abdominal fluid were dead, and as they died 
rapidly when kept in this fluid at the temperature of the body, it was 
suspected that the abdominal fluid was not a natural habitat. The 
living organisms were spherical or ellipsoidal in form, with a diameter 
from 15 to 38m, and had at one pole a small villous knob. Specimens
