 Hospital, Brighton, in August 1918 and again in June 1919. 

 Sixty-nine persons were examined in all. Most of these persons 

 were inmates of the Workhouse Infirmary, but a few were 

 patients in the Borough Sanatorium. None of the sixty-nine 

 persons concerned were suffering from any intestinal complaint.' 



The ages of the persons varied from nine years to over

 cases were examined once only, sixteen were examined twice, 

 three were examined three times, and the other four more often.

Endolimax nana 

 Giardia intestinalis 

 Chilomastix mesnili
