control of tlie salt-marsh mosquitos, Aedes cantator and A. sollicitans 

 and other marsh and sewage species. Attempts were made to find 

 some larvicide that would be an improvement on those known, but 

 sulphuric acid, chlorine and solutions of nitre cake (a by-product of 

 gun-cotton) all proved less successful than oil. Electrolysis of pools 

 ■was tried without any success.

This paper reviews the intestinal diseases caused by Protozoa that 

 have been prevalent in the war zones, especially in the tropics, and 

 mentions the principal Protozoan parasites of the blood that are 

 conveyed by insects.

During the period from March to October 1914, malaria was of 

 sHght importance compared with dysentery and ankylostomiasis, 

 but it remains a subject demanding more attention than in Deli 

 and other districts. 



The following mosquitos were collected : Anopheles {Cellia) koclii, 

 Don., A. {Mijzomyia) rossi, Giles, A. (M.) ludlowi, Theo., A. {M.) leuco- 

 sphyrus, Don., A. aconitus, Don. {alhirostris, Theo.), A. {M.) punctulatiis, 

 Don., A. [Myzorhynchus) sinensis, Wied., A. (M.) barbirostris, Wulp, 

 A. (Nyssorhynchus) fuliginosus, Giles, A. (N.) schiiffneri, Stant.

This paper details an investigation of the drainage and other 

 sanitary measures at the malaria-infected port of Telok-Betong, 

 which was formerly expected to become the southern terminus of the 

 Simaatran railway system, but is now superseded by the neighbouring 

 port of Sepandjang. 



The following mosquitos were collected in the Lampongs : Anopheles 

 (Cellia) kochi, Don., A. (Myzomyia) rossi, Giles, A. (M.) ludlowi, 

 Theo., A. (M.) leucosphyrus, Don., A. (M.) aconitus, Don., 

 A. (M.) punctulatiis, Don., A. {Myzorhynchus) sinensis, Wied., 

 A. (M.) fuliginosus, Giles, A. (M.) schiiffneri, Stant., and 

 A. (M.) barbirostris, Wulp. 



A. rossi is not very particular in the choice of breeding sites, but 

 A. aconitus and A. fuliginosus exhibit a preference for clean water 

 which is changed regularly. A. barbirostris was found during several 

 weeks in roadside pools. On one occasion one single specimen of 

 A. ludlowi was taken from a pool in the hinterland. Whereas at
