medicine. Because of the possibility of impurities, only a pure and care¬ 
fully refined carbon tetrachlorid should be used. While this drug de¬ 
serves consideration with especial reference to hookworms, it is also very 
effective for removing ascarids, being somewhat inferior to chenopodium 
in this respect, and will remove whipworms, as other anthelmintics will, 
when it gets into the cecum. It is not of value against tapeworms.
