This paper describes the mosquito nets adopted by the armies of the 

 United States and Japan. The Japanese type, which the author con- 

 siders the more effective, consists of a cylinder of net supported by two 

 rings of steel, about 10 inches in diameter, which are kept apart by a 

 spiral of the same metal. The upper part of the cylinder is closed ; 

 to the lower ring is attached a fold of cloth which can be placed closely 

 round the neck when the net is worn. The net can be folded up when 

 not in use.

 of Sale, Morocco.] — Bull. Soc. Path. Exot., Paris, ix, no. 3, 8th 

 March 1916, pp. 140-142, 6 figs. 



The presence of Stegomyia fasciaia in the coastal districts of Morocco 

 has already been dealt with [see this Revleiv, Ser. B, iv, p. 40]. Other 

 species occurring from September to February are : — Anopheles 

 maculipennis, Culex annulatus var. marocanus, var. n., and C. fatigans. 

 Anopheles become very scarce from October onwards, but a small 

 number are still found up to the beginning of January, which is 

 the coolest period of the year. The disappearance of malaria 

 coincides with that of the Anopheles. A. maculipennis appears in 

 April and disappears in September. C. annulatns var. marocanus, 

 which is seldom found indoors, is described. C. fatigans disappears 

 in the very cool weather and reappears with a rise of temperature. 

 It oviposits everywhere, especially in the cesspits of Arab houses.

 domestica). [Transmission of leprosy by flies {Musca domestiea).] 

 — Ann. Inst. Pasteur, Paris, xxx, no. 2, February 1916, pp. 61-68. 



The fact that house-flies are capable of transmitting leprosy has 

 been recorded by several investigators and further observations on 

 this subject were carried out by the author during 1913. In the 

 preliminary experiments, flies which had been allowed to feed on a 

 pulp obtained from the glands of strongly infected rats were enclosed 

 together with wounded rats. The flies, upon dissection, showed the 

 intestine to be filled with a reddish matter formed from the glandular 

 pulp, and containing enormous numbers of bacilli. Examination of 

 the rats after a considerable interval showed that infection had occurred 

 only in the case in which septic material had been present throughout 

 the experiment. Further experiments showed that failure to infect 

 was due to the drying up and consequent death of the bacilli on the 

 feet and proboscis of the flies ; infection only occurred when these 

 parts had been recently soiled. When bacilli from the intestine were 

 introduced beneath the skin of rats, infection followed in all cases. 

 Female flies were found to absorb more septic material than males, 

 and the same material remained alive for a longer period in the intestine
