Similar work is described in Kassandra, Stauros, Mitylene, Imbros, 

 and Syria, in all of which conditions were greatly improved. The 

 author has reached the conclusion that quinine should be administered 

 in solution, in intermittent lethal doses, in malarial localities where 

 infection is expected and especially under active service conditions. 

 If, however, nets can be used every night and there exists an efficient 

 anti-malarial prophylaxis, quinine may be reserved until its use is 

 indicated. The treatment of the disease is discussed, the author 

 considering that the best treatment of malaria, after the pyrexial 

 stage and in the subsequent course for the prevention of relapses, 

 consists of an early and effective combination of arsenic with quinine. 



The Aegean Islands are as yet largely undeveloped, and money is 

 required to undertake scientific drainage before they can be made as 

 healthy and prosperous as they might well become.

 sauvages. — Rev. Zoologique Africaine, Brussels, vii. no. 1, 25th

Wild animals have been proved to be the reservoir of infection of 

 trypanosomiasis, and from them the disease is transmitted by Glossina 

 to domestic animals. 



Experiments further prove that the strain in the blood of these 

 animals is much more virulent when injected directly into domestic 

 animals than when transmitted by Glossina, although the relative 

 number of trypanosomes contained in it is very small as shown by 

 laboratory examinations. The decrease in virulence of trypanosomes, 

 when transmitted by Glossina, is probably due to the change they 

 undergo in the alimentary canal of the flv.

Observations have been made to determine the northern fimit of 

 Glossina morsitans between the Lualaba River and Lake Tanganyika. 

 The country from Kasongo to Kabambare, which varies greatly both 

 as to elevation and vegetation, is described. Along this route four 

 species of Glossina have been foimd, namely, G. joaJpalis, G. imllidipes, 

 G. morsitans and G. brevipalpis. 



G. palpalis, R. D., was met with along rivers wherever there were 

 sufficient trees to furnish the required shade and humidity, as well as 

 in abundance on the shores of Lake Tanganyika. In some places, 

 although the conditions seemed favourable, the flies were not found 

 in great numbers owing to the altitude. 



Glossina pallidipes, Aust., was found together with G. morsitans 

 to the east of Kabambare in plains of sparse vegetation, but disap- 

 peared towards Niembo. It was also met to the north of Kongolo, 

 where G. morsitans is not present.
