Gaiger (S. H.). a revised check list of the animal parasites of 

 domesticated animals in India. — Jl. Comp. Path. Therap., London, 

 xxviii, pt. i, March 1915, pp. 67-76. 



This is a revision and extension of the list published in 1910, in the 

 Jl. of Trop. Yet. Sci., v, no. 1. The internal parasites are 

 arranged under the part or organ affected. The external, under ticks 

 (16 spp.), Diptera (62 spp.j, fleas (1 sp.), lice (13 spp.), mange 

 parasites (10 spp.) and cutaneous Filaria (3 spp.).

The author states that figures and conclusions show so clearly that 

 contagion or infection through immediate contact is the usual mode 

 of communication of leprosy, that it appears rather far-fetched to 

 seek an insect carrier of this disease. All experiments to prove this 

 mode of transmission have so far failed, though it appears quite 

 probable that the common house-fly can acquire the germs of the 

 disease from open sores, carry them about for several days, and 

 disseminate them. 



Leboeuf examined numerous specimens of Musca domestica caught 

 on the sores of lepers. He found leprotic " globi " in the intestines 

 of flies captured and kept for twenty-four hours, and acid-fast 

 rods in flies thirty-six hours after feeding. He concludes that 

 31. domestica can absorb enormous numbers of Hansen's " bacilli " 

 from sores containing these germs. The " bacilli " can be found 

 in abundance and apparently healthy in the excreta of infected 

 house-flies. Multiplication does not seem to take place in the 

 digestive tract of Musca domestica, though there are no signs of 

 degeneration. M. domestica possibly plays an important parb in the 

 dissemination of leprosy by depositing its excrements on the mucous 

 membranes or small abrasions of the skin of healthy people living in 

 the immediate vicinity of lepers. No insect is yet known to act as 

 the true intermediate host of any bacterial disease. With bacteria, 

 a contaminatory communication through the faeces or by the regur- 

 gitation of the crop contents takes place. This is the case in bubonic 

 plague and typhoid. The house-fly is eminently adapted for a con- 

 taminatory or mechanical method of dissemination, but the difiiculties 

 inherent in the communication of leprosy to animals will render 

 experimental work in this direction very difficult to accomplish.

 Belgian Congo. — Ann. Trop. Med. Parasit., Liverpool, ix, no. 1, 

 18th March 1915, pp. 163-168. 



This paper, to which Mr. H. F. Carter has added the entomological 

 notes, describes the mosquitos of Kabinda, a healthy station about 

 2,800 feet above sea-level. There are no swamps, and mosquitos are 

 relatively rare and very sensitive to seasonal variations, being more 

 numerous at the beginning and end of the rainy season, when the rains 

 are not excessive. A specimen of Stegomyia fasciata was caught and
