as we were able to discover, Anopheles never breeds in such 
situations, this carelessness and apathy of the inhabitants o£ a 
mosquito-infested country towards a notorious enemy to comfort, 
though not perhaps to life, is really astonishing. Among the 
natives, indeed, this apparent carelessness is doubtless often due 
simply to ignorance ; but even Englishmen, who ought to know 
better, are, as a rule, equally apathetic. 
Anopheles in A few days after our first visit to Kissy, the same species of 
for '^■ os ^ ta ^ Anopheles that had been met with in the lunatic asylum was 
Incurables. found by me in the Hospital for Incurables, which is situated 
near Kissy, about a mile away from the village and asylum. 
Here, again, the insects were always discovered at rest on the 
' darkest part of the walls. 
To reach the hospital one has to cross about half a mile of 
marshy ground, which is covered with grass and contains 
numerous small pools of stagnant water, besides streamlets ; but 
no sign of mosquito larvae, either Anopheles or Cidex, could be 
found. 
Anopheles Our attention was next directed to the half -battalion of the 
wflber/orce ^ r( ^ ^ est India Regiment at Wilberforce, which, in proportion 
to its strength, was suffering severely from fever. On August 17th 
we paid a visit to the barracks there, and caught a number of 
specimens of Anopheles, which we found resting on the walls of 
the hospital and several of the other huts. We endeavourel to 
find their breeding-place, but without success. The species 
(which has since proved to be Anopheles costalis, Lw.) was 
larger than that found at Kissy, but identical in habit, the 
insects adopting precisely similar resting postures, and always 
keeping to the darkest parts of the walls. 
Except as the result of unsuccessful attempts to capture it, 
no Anopheles was ever seen on the wing in the day time, either on 
this occasion or subsequently, and there seems no reason to doubt 
the assertion of the men of the West India Regiment, that, as a 
rule, these mosquitoes bite only at night— an observation already 
confi rmed by the published statement of a scientific observer. The 
female insects caught at rest during the day were in most cases 
found to be gorged with blood, but I never captured a male in
