§ Dr. Kingasked the Secretary of State for the Colonies whether any drive against the causes of malaria is taking place in the West African Colonies comparable to those carried on in Ceylon and British Guiana with the aid of D.D.T.
§ Mr. J. GriffithsIntensive measures are being taken against the causes of malaria in certain areas in all the West African territories and modern insecticides such as D.D.T. are being used where their use is practicable and likely to be of value. It is not possible to compare this work with that carried on in British Guiana and Ceylon because different species of malaria-carrying mosquitos, and other factors such as terrain and population density, call for varying methods in the scientific approach to the problem.
