is, of course, equally important to try to 

 destroy the parasite in man by means of 

 quinine. This is, however, a matter of great

 though they suffer little, and gradually acquire 

 a high degree of immunity. Still, they are 

 always a source of infection ; and soldiers 

 stationed in malarious districts should always 

 place their dwellings to the windward of 

 the native settlements. 



Knowing the cause, we can now guard

 protected windows and doors are a sufficient 

 check on the access of Anopheles to man. 

 If the mosquito and man could only be kept 

 permanently apart, we might hope for the 

 disappearance of the parasite from our fauna. 

 In relieving man from this world-wide pest, 

 all genuine lovers of animals will rejoice that 

 we are also relieving the far more serious 

 lesions of one of the most delicate and 

 beautiful insects that we know. 



It has always been a source of surprise 

 to me that the great resources and the very
