Time ami opportunity did not permit of the collection of a larger series of cases ; it was found especially difficult to 
obtain children for examination in country districts ; still it will be seen that the malaria index in Bathurst is very high, and 
consequently the chance of infection for the new-comer under suitable conditions is also very great. 
It is of interest to note the high percentage of quartan parasites (Haemamoeba 
malariae) among the cases examined, viz., 31*8 per cent., and also the large percentage 
of crescents (gametocytes) observed in the blood, viz., 32*3 per cent., in those cases 
in which the aestivo-autumnal fever parasite (Haemamoeba praecox) occurred. I believe 
this large percentage has not been observed before on the Coast. 
The parasite of tertian fever (Haemamoeba vivax) was only found in three cases. 
The children infected at Bathurst came from all parts of the town, and no 
indication was obtained from the examination of their blood that malaria was less 
prevalent in one street than in another ; considering the small size and the equal dis- 
tribution of suitable breeding-places for the malaria-carrying mosquitoes throughout 
the town, it is not to be expected that at any one part the malaria index would vary. 
Table II gives the results of the child examination in the Gambia.
