CONCLITSIONS. 



1. Balantidium coli is a parasite and, although not so common an 

 infecting agent as the amoeba, in individual cases it is more serious in its 

 effects. The prognosis in early cases is bad and in late ones practically 

 hopeless. 



2. A search through the literature fails to show a report of splenic 

 infarction due to filarial embryos in an uncomplicated infection. In- 

 farcts of the spleen with numerous filarial embryos present have been 

 reported in a case of Bubonic plague." 



Infarctions occur frequently in plague and it is possible that the 

 embryo filarise in the case cited above were only present coincidently and 

 not the primary cause of the infarction.
