only practicable measure under the present regulations is to send 

 them all to the slaughter-house, or to maintain the depots for sick 

 horses until the last case is cured. The author suggests that the 

 present and future needs of agriculturists should be more carefully 

 considered, and that the preliminary step in this direction should be to 

 entrust the depots for sick horses to those whose business it is to cure 

 them.

Proc. Enlom. Soc. Washington, D.C., xviii, no. 4, December 1916, 

 pp. 208-211. 



Tabanus trijunctus, Walk., and T. lineola, ¥., are commonly attracted 

 to moving objects such as trains, motor-cars and wagons, and attack 

 unprotected horses until their bodies become covered with blood. 

 They also occur in buildings, especially stables, but are present in 

 numbers sufficient to constitute a pest only during the latter part of 

 March and the beginning of April. Other species are T. inexicanus, 

 L., which is nocturnal in its habits, and T. americanus, Forst. Cats 

 and dogs are also attacked and become emaciated from the irritation 

 caused by these flies.

 — Public Health, London, xxx, no. 8, May 1917, pp. 176-180. 



An outbreak of bubonic plague at Bristol was traced to a rag ware- 

 house there. Over 8,000 rats were caught and examined in the city 

 and port. Of the first 432 rats examined during August and September 

 1916, 6 were plague infected, all from the rag warehouse, and on one 

 of them, Mus decmnanus, the Indian flea, Xenopsylla cheopis, was 

 taken. On the remainder of the rats the common rat flea, Cerato- 

 phyllus fasciatus, was found in large numbers, together with several 

 species of lice.

 Sudan. — Jl. Trap. Med. Hyg., London,xx,no. 12, 15th June 1917, 

 pp. 183-185. 



Nearly 300 cases were observed in two months during an epidemic 

 of six- to seven-day fever which first appeared in the middle of July, 

 soon after the commencement of the rains. The only mosquito 

 then prevalent was Stegomyia fasciata {calopus). As a result of 

 effective anti-mosquito measures, the epidemic diminished appreciably, 

 but a few cases still persisted among the British troops quartered 

 in barracks. An examination of the barrack rooms was made, when 

 the walls were found to be heavily infested with Cimex lectidarius. 

 As any evidence implicating other blood-sucking insects was lacking, 

 it was assumed that this bug was capable of transmitting the disease.
