The isolation of the virus of poliomyelitis from the sewage in Johannesburg is descriptionbed. The virus was not detected in the final effluent after the process of purification in the sewage Works. The possible significance of the finding is discussed, and it is noted that the role of infected faeces and sewage in the spread of poliomyelitis has not yet been clearly determined.

A hypothesis is advanced that smaller doses of antimony than those previously given in the intensive treatment of bilharziasis may render the human host non-infectious by killing the female worm. The value of this disinfestation is briefly discussed.
