drainage, or in some other way an insanitary condition of the infested 

 section, and that the radical and scientific treatment of this condition 

 is proper drainage and a compliance with modern sanitary regulations. 

 Any other treatment is proper only when these measures cannot be 

 enforced, and it is under the latter conditions that the use of petroleum 

 is indicated. The responsibility of carrying out this important work 

 must rest with the municipal, State, and Federal authorities. Municipal 

 sanitary codes should include strict regulations, not only against the 

 existence of stagnant pools but of all forms of breeding places, and 

 should empower sanitary officers to employ such means as are 

 necessary to protect the public against these insects ; and, when 

 required, the application of oil should be made under their direction. 

 In order to make this work uniform and effective the co-operation of 

 the State and Federal authorities is absolutely necessary, and such 

 action would, Dr. DOTY thinks, be followed by the most gratifying 

 results. 



Some Further Work on the Mosquito -Malaria 

 Theory, with Special Reference to Conditions 

 Around New York, by WILLIAM N. BER- 

 KELEY, A.B., M.D.*

As a fair example of what may be locally accomplished I cite a 

 small outbreak of malaria in a suburban New York town last summer. 

 In August I was requested by one of the resident physicians to go 

 there, examine the ground, and advise means of prevention. The 

 conditions were briefly these : 



Around a large pond in the vicinity of the town four or five fresh 

 cases of malaria had recently developed. The first case was that of a 

 coachman who had caught malaria elsewhere and had relapsed. 

 From his quarters, in a long row of stables at one side of the pond, 

 the infection had passed along to other stablemen and servants on 

 the same side to the distance of a quarter of a mile from the original 

 site. A quarter of a mile in another direction across the pond one 

 other case appeared in a small child. A. quadrimaculatus was fairly
