§ 16. Captain PETER MACDONALDasked the Secretary of State for the Colonies whether his attention has been called to the discovery by the director of the Natal Museum of the origin of the tsetse scourge in East Africa; and whether he can make any statement on it?
§ Sir P. CUNLIFFE-LISTERI am informed that a theory has recently been advanced that the trypanosomes of nagana transmitted by tsetse flies originate in plants, and not in animals, as generally believed. I am advised, however, that this theory is not borne out by the observations of expert tsetse investigators, and is not generally accepted by the highest authorities.
