I. Introduction. 

 II. Case Eecokd. 



III. Pathogenesis of the Cieehosis of the Livek. 



IV. Comparison of Infection with Schistosomum Japonicum and 



SCHISTOSOMUM HiEMATOBIUM. 



V. Geographical Location. 



i. introduction. 



Schistosomum japonicum was discovered and described as recently as 

 1904, although the disease which it produces had been recognized in Japan 

 for nearly two decades previously. Outside of a small area in Japan, cases 

 of infection with this blood fluke are still so infrequently seen that each 

 one is worthly of report and discussion, as such reports will aid in locating 

 the geographical distribution of the parasite and in clearing up its life 

 history and pathologic effects. In discussing the present case, we wish to 

 speak particularly of the pathologic findings in it and in other recorded 

 cases, and to draw a contrast between these and those of infection with 

 the closely allied Schistosomum haematobium. 



II. case record. 



The patient, P. O., was admitted on January 16, 190S, to Dr. Ruffner's service 

 in the Division Hospital in this city, and died on the following morning. He was 

 a Filipino soldier 30 years old, belonging to a Visayan Scout company, single, 

 and a native of Calbayog, Samar, in which town he lived continuously until his 

 twenty-fourth year. He then enlisted and during the six years of his service 

 was stationed on the Islands of Panay, Cebu, Leyte and Samar. He had never 

 been out of the Visayas except for short visits, and lie was on furlough in Manila 

 when he entered the Division Hospital. The sick record of his company shows 

 that during the six years of his service he was in hospital one hundred and 

 nineteen days and in quarters eighty-three days, although the causes of admission 

 to sick report are not given.
