case becoming infected, while in the other two, the lack of infection 

 was due to the non-infectious state of the subject, and not to any 

 immunity on the part of the mosquito. 



In order to prove whether these infected mosquitos were capable of 

 transmitting the disease to a healthy subject, the author allowed 

 himself to be bitten, with the result that fever developed in due course 

 and Plasmodium vivax was found in his blood. The existence of 

 immune mosquitos therefore seems to be improbable.

There can be little doubt as to the occurrence of malaria in France 

 arising from the presence of discharged soldiers from the Eastern 

 armies, and a Commission has been appointed to propose suitable 

 methods of control. These consist in sending malarial convalescents 

 to localities free from Anophelines, in which places special hospitals 

 for malaria patients should be established. When it has not been 

 possible to send malarial convalescents to such a locahty, the danger 

 of transmission has been reduced to a minimum, by the use of mosquito 

 nets and by subjecting the patients to a long and intensive quinine 

 treatment so as to free the blood from the parasites. Thanks to these 

 measures and to weather conditions unfavourable to the spread of the 

 insect, the transmission of malaria by returned soldiers to residents in 

 the non-malarial parts of France has been extremely rare.

In view of the possible danger of centres of malarial infection 

 becoming established in France in consequence of infected soldiers 

 returning from the Balkan Army, a research service has been instituted, 

 under the control of a central committee, to direct the choice of 

 positions for malaria hospitals and to issue circulars conveying 

 information regarding Anopheline mosquitos that carry the disease. 

 Acting on the advice of this committee, the Under Secretary of State 

 has divided France into five great districts with sub-divisions, each 

 under the direction of a zoologist who has sj)ecialised in the study of 

 malaria and mosquitos. In addition to these measures, the public 

 are invited to send to the specialist in charge of their district sj)ecimens 

 of any mosquitos taken in houses and to report the discovery of any 

 stagnant pools containing mosquito larvae, especially those of 

 Anophelines. Medical men are also asked to collaborate by reporting 

 the localities in which they have found cases of malaria.
