South Africa, and it is therefore a matter of great importance that any 

 Avarbles in imported cattle should be destroyed. The present state of our 

 knowledge of the mode of attack of Hypoderma lineatmn and H. hovis 

 is briefly set out, and the ordinary methods of treatment are given. 

 It is stated that last year an apparently warbled hide was sent to the 

 Department of Agriculture, and the fact was confirmed by an eminent 

 British authority. This hide was said to have been purchased and 

 tanned in South Africa, but the author thinks that it is more than 

 probable that it came from an imported animal, and not from one bred 

 and reared in South Africa.

This article deals generally with the parasites of poultry, particularly 

 with the mite which attacks the legs of the birds, producing the 

 so-called " scaly leg." This minute parasite bores in the epi- 

 dermis, mostly between the toes and under the claws, but also spreads 

 over the plumage. At the beginning of the disease small scales of a 

 greyish colour are noticed on the legs of the birds, the scales gradually 

 changing into yellowish grey crusts, and the legs appear as if covered 

 by a coat of hme ; the birds become lame, death resulting from 

 exhaustion. The remedy consists in softening the crusts with glycerine 

 or soft soap, and brushing them off and rubbing in afterwards an 

 ointment made of subhmed sulphur, 15 parts, prepared chalk, 7 parts, 

 and lard, 60 parts. Smearing with tar or with a mixture of kerosene 

 and hnseed oil in equal parts is also recommended. All woodwork in 

 poultry houses should be smeared wdth a 5 per cent, solution of carbohc 

 acid, and the floor, walls, etc., washed with milk of hme, containing 

 one tablespoonful of creohn in every quart. 



James (Major S. P.). Summary of a year's mosquito work in Colombo, 



— Indian Jl. Med. Research, Calcutta, ii, no. 1, July 1914. 

 pp. 227-267. 



This is a summary of a Mosquito Survey of Colombo conducted in 

 1913. The mosquitos in that city may be divided into five broad 

 groups, of which the two first may be classed as urban, the three last 

 as rural: (1) Strictly household species, (2) other urban species, 

 (3) strictly sylvan species, (4) migratory species, (5) species with 

 pecuhar habits. It has been proved, in Colombo, that the mosquitos 

 of groups 1 and 2 can, by strictly local measures, be reduced to a 

 number that is practically*^ negligible, but that mosquitos of group 4 

 will continue to be troublesome in the town at certain seasons, however 

 thoroughly measures confined to the town itself are carried out. Traps 

 should prove of real value in deahng with these migratory species, 

 as it appears that in Colombo about ten million mosquitos might be 

 caught daily by this means, and this would be more effective than the 

 destruction of a thousand milhon larvae. Against these migratory 

 species anti-larval methods are not at present recommended for 

 Colombo, except when required for purposes of investigation. It was 

 the rule to investigate thoroughly each house and compound in the
