INTESTINAL SCHISTOSOMIASIS 



freshly discharged cercarise do not usually live in it for more than 

 twenty-four hours. Chemical sterilization may be carried out by 

 using sodium bisulphate tablets, each containing i grm. of the 

 chemical. Two tablets are dissolved in a quart water bottle. 

 Leiper has shown that sodium bisulphate in a dilution of i in 1,000 

 is lethal to the cercariye. For small detachments of troops in outside 

 districts Leiper recommends that the drinking-water should be 

 separated from ablution water, the former being sterilized by boiling 

 or by tablets of acid sulphate of soda, while the ablution water 

 should be rendered safe for immediate use by adding ordinary Cresol 

 in the dilution i in 10,000.
