As the more practical of our reports to the Malaria Committee have not yet been published, i..., those showing how extremely feasible and certain is segregation of Europeans from native quarters as a means of Malaria, we think the following brief abstract of our views on the prophylaxis of malaria may be of value.

1. The anopheles which infect Europeans do not derive their infection from other Europeans, but from natives, i.e., from the native children who almost without excep. tion suffer from continuous malaria.

2. It is universally the practice in tropical Africa to allow and even encourage native huts to be built close to European houses. These huts always contain numerous children with parasites and anopheles with sporozoites ready for injection.

3. We are aware that segregation is supposed by some to be impracticable. We have ourselves spent much time, however, in Government officials' quarters, railway camps, missions, traders' stations, and we can confidently assert that segregation from the native is far the most practicable of any scheme yet put forward for prophylaxis of malaria, indeed it is difficult to imagine that anything more certain, more simple, and more easy of application is likely to be discovered.

4. The exponents of schemes for the destruction of anopheles grant that their schemes can at the best be only applicable to large towns. Segregation on the other hand is not only possible in many large towns, but could be carried out almost devoid of cost throughout the vast regions of Africa where white men live either alone or in small scattered communities.

5. In the building of European quarters it rests with the chooser of the site and the occupier to exclude or introduce malaria. It is almost painful to see how in cre place after another the European through ignorance is placing himself in the midst of abundant native malaria, and to know how little would suffice to banish the discase which is sapping his vitality.

The accompanying plan is that of a railway terminus built within the last year. It was possible at the time of building to have chosen a site far removed from huts and therefore from malaria infection. Instead of this the new quarters were erected almost within a native village and the result, as might have been anticipated, was much malaria.

6. The recent expedition to Nigeria sent out by the Liverpool School are con- vinced with us that segregation from natives is at present the only scheme of pre- venting malaria that offers the least possibility of success in Africa.

To the Malaria Committee.
