THE PRESENT EPIDEMIC OF MALARIA. 881 



in the Fort, the hinged trap-door, now generally used on these 

 cisterns, must be replaced by a more accurately fitting cover to pre- 

 vent mosquitoes gaining an entrance to the water. Again the best 

 treatment for disused wells is to have them filled up. 



Dealing with the breeding places of stephensi in this rational way 

 we can appreciate what effect our measures are having by collecting 

 the adult insects from time to time and observing whether they are 

 more or less easily found. If still they continue to be easily captured, 

 then we must seek some other, yet undiscovered, breeding place. 



In bringing this paper to a close and thanking you for your patient 

 hearing, I feel sure that you will agree with me that the time has 

 arrived when a thorough enquiry should be made into the conditions 

 which have brought about this epidemic, and that measures should be 

 at once taken to deal with the situation in some more thorough way 

 than has been attempted in the past.
