Accounts of earlier investigations on this subject by one of the 

 XDresent authors have already apjDeared [see this Review, Ser. B, iii, 

 p. 207, and v, p. 110]. The experimental results of the work here 

 detailed were, in both instances, negative, owing to the small number 

 of both Tabanids and mosquitos present during the season.

Among the insect-borne diseases dealt with in this report are plague, 

 which occurred on two vessels arriving in the Thames. Both ships 

 came from the infected port of Bombay and carried cargoes attractive 

 to rats, Mus rattus being the species commonly found on board. There 

 was no extension of the infection after the vessels had been dealt 

 with by the London Port Sanitary Authority. Louse-borne diseases 

 such as typhus and trench fever largely increased owing to War 

 conditions, and infestation by lice and scabies have become wide- 

 spread among the civil population. Recently, however, methods 

 adopted for disinfection and destruction of lice in the army have 

 greatly increased in efficiency, and up to the present there has been 

 no case known in which soldiers returning to this country have brought 

 with them the infection of typhus, or of trench fever. During 1917, 

 178 cases of locally-acquired malaria were recorded in England. The 

 areas afiected were mostly those in which malaria or ague had been 

 very prevalent up to the middle of the last century, and it is probable 

 that in these and other areas a considerable risk arises of the re- estab- 

 lishment of endemic centres of malaria owing to the return from abroad 

 of men who are carriers of the malaria parasite.

The study of the geographical distribution of Anophelines in South- 

 ■eastern France in the region east of the Rhone ie of great interest 

 on account of the varied climatic and physical features of this region. 

 High mountains, elevated plateaux, hills, and wide or deeply cut 

 valleys, afford varied habitats for each of which the presence and 

 distribution of an Anopheline species and its relation to ancient or 

 present-day malaria must be worked out. Although the exploration 

 £>f this region is not completed, it is clear that the distribution of
