RECOMMENDATIONS 
Above we have discussed at some length the practicability of some of the 
suggestions which have been advanced, either singly or together, as general methods 
for the prevention of malarial fever in a European community. We have shewn 
that in a great measure they are unsuitable for adoption on a large scale in Nigeria — 
partly on account of unreliability and inefficiency — partly because of the enormous 
expense. But it must not be understood that we wish to discourage in any way the 
use of the more reasonable of them as measures of some value under certain circum- 
stances, but they are throughout to be considered very subservient to the measures to 
be suggested ; and though by their employment the chances of infection of malarial 
fever would be more or less diminished, absolute protection against the disease could 
never be obtained. 
I. Segregation of Europeans at a Distance of about half-a-mile 
from Natives 
The fact that the native children especially constitute a perpetual source 
of danger to the European, as being naturally the source from which he is infected 
with the parasites of malarial fever carried from the native by the mosquito of the 
genus Anopheles, suggests very pointedly that the safest and surest plan on the part 
of the European to guard himself absolutely from any chance of infection would be 
to live at a distance from the native. 
This would have been unnecessary, of course, had the possibility of the 
suggestion of the use of quinine wholesale among natives been feasible, but the 
enormous quantity of the drug that would have been required, and the more or less 
uncivilised condition of West African natives, have been shewn to render the plan 
impossible. 
Similarly, it having been shewn how a total and universal destruction of the 
insects by any practical means is impossible, and, moreover, since mosquito-proof houses 
are not at all capable of protecting Europeans from the bites of Anopheles at all times 
of the day and in all the varying circumstances of European life in West Africa — 
since, indeed, they are impracticable on a large scale — the adoption of the measure 
of segregation from the native is still more strongly indicated 
Segregation of Europeans at a distance from all natives offers itself now as the 
only measure by which absolute freedom from the disease can be guaranteed, and all 
the scientific evidence that has been collected respecting the cause of malarial fever 
and the manner in which infection among Europeans is brought about, markedly
