whenever the}'' engorge on the blood of a healthy pigeon, but do not 

 become immune against reinfection. A cleansing of the flies cannot 

 take place so long as they feed upon infected pigeons. Artificial 

 transmission from infected pigeons to healthy pigeons cannot be 

 brought about by ordinary blood inoculation, but is easily effected by 

 the injection of ookinetes cultivated in the moist chamber. Direct 

 transmission is also possible if lung material be used.

This is an annual report on anti-malarial work in Algeria [see this 

 Review, Ser. B, iii, p. 143]. In 1914 a distinct increase of malaria was 

 observed in many localities. At certain points it was epidemic in 

 character and fatal cases were numerous. The breeding of Anophelines 

 was furthered by the absence of many Europeans owing to the war. 

 The boring of artesian wells to supply the needs of intensive cultivation 

 also proved favourable to moscpiitos, as the abundant output of water 

 does not find a sufficient outlet and stagnant pools are formed. The 

 spring of 1914 was wet until a late date and the level of the underground 

 water rose nearly everywhere, after being very low during preceding 

 years. The peculiar habits of Anopheles turkhudi {Pyretophorus 

 myzomyifacies), which is nocturnal in habit and very rare indoors by 

 da}^, was again noted at Madani, where malaria was rife in 1914, though 

 the inhabitants declared they had hardly ever been bitten. Pools. 

 near the houses swarmed with the larvae of this mosquito. Anti- 

 larval measures gave excellent results and were only interrupted in 

 some places in August owing to the war. Quinine prophylaxis was 

 continued and proved of undoubted value. A quantity of literature 

 was distributed, a specimen being reprinted in this paper.
