Since the use of carbon tetrachloride as an anthelmintic is becoming so general the question has naturally arisen as to what its effect is on the intestinal protozoan parasites of man.

THE EFFECT OF CARBON TETRACHLORIDE ON INTESTINAL PROTOZOA IN CULTURE In the fall of 1921 one of the authors had in the laboratory cultures of Trichomonas hominis, Embadomonas intestinalis and Spirochaeta eurygyrata. They were all living on a culture medium known as sodium chloride serum water (Hogue (1)). This is a combination of 0.85 per cent sterile solution of sodium chloride and either sheep or pig serum water made up with sterile distilled water in the proportion of 1 part of serum to 3 or 4 parts of distilled water.
