acid sulphate, containing about 30 per cent, free acid. This substance 

 being solid and partly granular, dissolves slowly, and it has been found 

 that in water containing 10 per cent, by volume of the sulphate the 

 mosquito eggs will hatch, but the larvae nearly all die, very few 

 reaching the pupal stage. In practice a much stronger solution 

 was obtained by well loading the pools. Grass and weeds around 

 the pools are killed by the acid, which is an advantage on land of 

 this character. Mosquitos appear to have been almost eliminated 

 and the cases of malaria have decreased, no new ones having been 

 treated during the year.

In 1917 several cases of a benign fever of the dengue type were 

 observed at Paramaribo, Dutch Guiana, a colony from which no 

 dengue or fever allied to dengue has ever been described. All the 

 well developed cases were in newly-arrived individuals or in children, 

 and none occurred among the Creole, negro and mulatto populations, 

 which enjoy an acquired immunity. Among the abundant mosquitos 

 present were Cnlex fatigans {quinquefasciatus) and Stegomyia fasciata 

 {Aedes calopus).

At Khartoum cases of oedema of the eyelids are ascribed to the 

 bites of ants, and it is stated in this paper that where ants were 

 kept away from beds by means of powdered camphor no swellings 

 of the eyelids occurred.

This is a detailed description of the measures successfully adopted 

 at Trinitapoh, pro\'ince of Foggia, against malaria. The work was
