 common. We did not succeed in finding infected forms. These 

 two canal branches are the sole sources of supply of fresh water 

 to Port Said and Suez. They are open to contamination with 

 bilharzia : (1) from villages upon the banks ; (2) from the pathways 

 running the whole course of the canal ; and (3) from shipping. 

 The water appears to be infective only to a relatively small degree, 

 because the children in the schools of Suez and Port Said show a

low percentage of cases. At Suez, one child out of nineteen in a 

 school on the outskirts of the town was infected. At Port Said, 

 according to Dr. Orme, bilharzia eggs were found in the urine of 

 five out of forty healthy pupils in the Government school. At 

 Ismailia, unfiltered water taken from the canal on the outskirts of 

 the town is supplied to the European houses and is actually laid on 

 as the cold water supply in the bathrooms. Had the canal water 

 been commonly infected a considerable number of cases of bilharzi- 

 osis should have been recorded among the European inhabitants.
