Les Parasites du B6tail. [Parasites of cattle.] — Eev. Agric. Vitic. Afr. 

 Nord., Algiers, xii, no. 123, 18th July 1914, pp. 68-69. 



A mixture of 5 oz. of assafoetida, 13 oz. of vinegar and 20 oz. of 

 water is said to keep Tahanus, Stomoxys and warble flies away from 

 cattle when the thinner-skinned parts of the body have been well 

 washed with it every five or seven days.

The waterworks for Alor Star, the capital of Kedah, F.M.S., were 

 under construction early in 1914. The water was tapped from two 

 streams, which united a little lower down, the coolie lines being situated 

 at the junction. From May to December 1913, only 10 coolies were 

 admitted into Hospital suffering from malaria, but there were 97 cases 

 in the first quarter of 1914. Though the course of the river had not 

 been interfered with, the water was very low and the following larvae 

 were found there in January 1914 : Anopheles leucosphyrus, A. Jcochi, 

 A. sinensis, A. maculatus, A. karwari aud Uranotaenia campestris. 

 To provide drinking water, a service pipe was brought down from well 

 above the lines, and pools which formed where the joints of the pipe 

 leaked, contained larvae of A. maculatus. At a later visit it was 

 found that the stream had been cut off from the dam and the original 

 bed was a series of shallow pools full of decomposing vegetation. The 

 only larvae then to be found there were those of Culex ager. Above 

 the dam, numbers of larvae of A. maculatus or A. karwari were obtain- 

 able. In a small jungle pool, fed by a spring, A. maculatus, A. leucos- 

 phyrus, Lophoceratomyia barkeri, U. campestris, and Culex co7icolor 

 were found together, evidently owing to the reduction in breeding 

 places.

Lyperosia irritans. — Jl. of Infectious Diseases, Chicago, xv, no. 1, 

 July 1914, pp. 1-5, 2 figs. 



Lyperosia irritans is found in great numbers on cattle and especially 

 black cattle, hardly ever on white or yellow animals. Six thousand 

 flies were collected, only four Stomoxys being found among them, 

 but great difiiculty was experienced in keeping them alive in captivity 

 unless constantly fed on living animals. Though freely fed on monkeys 

 inoculated with poliomyelitis and then allowed to bite healthy ones, 

 none of the latter acquired the disease. 



Extracts from the Report of the Chief Veterinary Surgeon for the Year 

 1913. — Rhodesia Agric. Jl., Salisbury, xi, no. 6, August 1914, 

 pp. 830-838. 



It is stated that regular dipping and enclosure from tick infection 

 of cattle in Rhodesia has been a successful preventive against piro- 

 plasmosis and anaplasmosis. The increase in the number of cases of 

 trypanosomiasis in the Hartley district seem to be due to the increase
