Swellengrebel has proved that Pediculus humanus (vestimenti) is 

 a factor in the spread of bubonic plague. That this also applies to 

 Pedicuhis capitis the author considers to be proved by five inoculation 

 experiments which are briefly outlined. The head-lice from a plague 

 patient were ground in a mortar with salt solution and the mixture was- 

 then injected into rodents, all the experiments being positive.

This paper details the investigations undertaken as a preliminary 

 to planning the sanitation of the malaria- infected port of Sibolga on 

 the west coast of Sumatra. Mosquitos were breeding in a number of 

 places. A number of Anophelines, thought to be all A. {M.) ludloivi, 

 predominated in small, isolated pools and in marsh grass. In another 

 group of breeding places, mainly consisting of " sawah " rice land, Culex 

 was predominant, other species present being A. (M.) ludlowi and 

 A. (M.) rossi. The anti-malarial measures advised are the clearing of 

 the breeding places marked on the maps accompanying this report, 

 quinine prophylaxis and the building of a system of covered channels 

 for deahng both with surface water and sewerage.
