In Durban, South Africa, three different racial populations live together. In one of these, the Native African, there is a high incidence of an acute fulminating rapidly fatal amebic dysentery. This form of the disease is not seen in either the European nor Indian inhabitants of the area. The three races differ as regards diet and to a certain extent as regards the conditions of hygiene under which they live. Certain possible factors giving rise to this difference between various races are discussed.
