The fresh water hshes of South Africa are imperfectly 

 known and still less is known of their habits. The great 

 benefits that would result from the discovery of some native 

 fish of similar habits to that of the Barbados lish and suitable 

 to this country are obvious, and such an investigation seems 

 a matter of necessity if active steps are to be taken in com- 

 bating malaria in this way. 



This is a matter of course more for combined action among 

 the different Provinces of the Union, and the Cape Province 

 has less to gain than the others, though it would appear 

 that malaria is endemic along the whole of the Orange River, 

 the malarial mosquito being found at Kimberley, Barkh^ 

 West, Vryburg, and Kuruman and " mucli of the disease 

 known locally as ' camp fever ' is in reality a mild type of 

 Malaria" (Thornton). 



The initiative in such an investigation might well be taken 

 by the Cape Province, and, with the co-operation of the 

 other Provinces might produce valuable results.
