and A . punctipennis were reared from the monthly collections, whereas 

 in 1918 the former was rare. As drainage, which is the most effective 

 remedial measure, cannot be practised at Herrin, owing to the necessity 

 for maintaining ponds connected with the mines, it is suggested that 

 the edges of these should be cleaned, that oil should be applied in 

 some way, and that they should be stocked with fish, especially 

 top-minnows.

 Present and Future. — Trans. R. Soc. Trop. Med. & Hyg., London, 

 XV, no. 5-6, 17th November & 15th December 1921, pp. 157-179, 

 50 figs. 



The character of the country and conditions found in Mauritius, 

 with especial relation to malaria, are described. Previous epidemics 

 are reviewed, and the advantages and possibilities of rendering the 

 island free from malaria are discussed.

 & 15th December 1921, pp. 190-197, 1 map. 



Investigations on the subject of filariasis and elephantiasis in the 

 neighbourhood of Lamu are recorded The clinical appearances of 

 these diseases, which occur along the coast of East Africa, with the 

 exception of the most northerly portion, and, the climate and physical 

 features of the island of Lamu are described. 



Ticks, fleas and lice are not very common, but bed-bugs [Cimex] 

 abound. The following mosquitos are universal : Culex fatigans, Aedes 

 argenteiis [Stegomyia fasciata). Anopheles {Pyretophonis) costalis and 

 Skusea {Hoii'ardina) pembaensis. Embryonic Filaria bancrofti were 

 found in the peripheral blood of all cases returned as infected. Up 

 to date, 35-33 per cent, of the cases examined show infection with 

 this filaria.

Med. Jl. of Australia, Sydney, 9th Year, i, no 1, 7th January 

 1922, 1-13, 4 charts. 

 An account is given of a disease observed near Adelaide closely 

 resembling typhus fever. The scattered nature of the cases and 

 the fact that no two occurred in the same house point strongly to 

 transmission by insects, though these were apparently not lice. The 

 balance of evidence is at present in favour of the cases being a form of 

 typhus, and that weevils or weevil-infested wheat are in some way 

 concerned in its dissemination, but further investigations are required 

 before this can be accepted as proved.

 Brug showed that though Cnlex fatigans is present and can convey 

 Filaria bancrofti, and there is no lack of intermediate hosts, the com- 

 parative rarity of filariasis at Batavia remains unaccounted for
