Qi/i/n'safiofi. — Systematic treatment with quinine of 

 infants and adults has had a very beneficial effect. 



Mkasfres directed against the MosquiTo Carriers 



1. A iitilarval measures. — These consist in improved 

 drainage : deepening shallow drains and making the 

 margins sharp-cut, and removing weeds ; also oiling. 



2. Pleasures ai^'ainsf the adult mosquito carriers. — 

 The systematic use of mosquito nets, and the screening 

 of houses. 



To sum up. The Algerian antimalarial campaigns 

 were commenced in 1902, and consisted in : 



1. Spreading the knowledge of the way in which 

 malaria was propagated. 



2. Giving a practical demonstration upon a suitable 

 scale of the markedly beneficial effects of antimosquito 

 measures in reducing malarial fever, for this purpose 

 choosing a place in a particularly malarial district and 

 subjecting it to the well-recognised antimosquito treat- 

 ment, viz. oiling and drainage and enforcing nets and 

 screening, and treating the dwellers in the area chosen 

 systematically with quinine. The result of these 

 measures has been the almost total disappearance of 

 anophelines in the treated area as compared with the 

 untreated district around, and the very marked diminu- 

 tion of cases of malaria amongst the Europeans 

 employed in the selected area as compared with those 

 Uving in the non-treated areas. Thus, in one experi- 

 ment, no case of malaria was reported amongst the 

 seventy-one European inhabitants, whilst twenty-seven 

 Europeans outside the area contracted the disease.
