treatment of scabies in either cattle or sheep, and the efficiency of the 

 bath is regarded as dependent on the polysulphides present. Home- 

 made dips are liable to great variations of strength, owing to the 

 quality of lime used, and to deterioration by storage ; considerable 

 decomposition also takes place during use from exposure to air, and 

 some sort of field test of the efficiency of the dip is therefore desirable. 

 The test used is a standard iodine solution, with sodium nitroprusside 

 as indicator ; the method, though not scientifically accurate, under 

 the conditions gives results which are good enough for the purpose. 

 A field testing oufit is described and figured, and tables are given by 

 which the quantity of concentrated dip to be added to each 100 gallons 

 of bath to restore it to standard strength (r5 per cent, sulphur as 

 sulphide) may be found by inspection.

 During 1913, 155 cases of acariasis were observed in horses and mules, 

 1 in an ass and 1 in a goat. Two cases of filariasis in camels and 12 

 cases of piroplasmosis in Sudanese cattle are reported, w^hile in 

 Egyptian cattle 318 cases of Texas fever and 90 of Egyptian fever 

 occurred. For trypanosomiasis the figures were : Camels, 5 ; horses, 2 ; 

 Egyptian cattle 1 ; Sudanese cattle, 1 ; and negative, 683. Piro- 

 plasmosis of Egyptian cattle is of four kinds : — Texas fever, a small 

 Piroplasma resembling that of Egyptian fever, Piroplastna mutans 

 and a fourth form with all the characteristics of East Coast fever, 

 which is serious and often fatal. As the disease is unknown as yet in 

 Egyptian cattle, the Sudanese cattle at Cairo and Luxor have been 

 searched for ticks and the following were found : — Rhipicephalus 

 bursa, Hyalomma egyptium, Amhhjomma lepidum, Margaropus [Boo- 

 philus) annulatus, Rhipicephalus evertsi, R. oculatus and R. sanguineus.

 laboratories.]— 5if^/. Soc. Path. Exot., Paris, viii, no. 1, 

 13th January 1915, pp. 34-36. 

 At the end of December 1913, the author brought back from Senegal 

 some twenty living pupae of Glossina palpalis and G. morsitans. The 

 cold felt during the voyage caused the older specimens to die, but the 

 more recently formed ones produced adults in the laboratory of the 

 Pasteur Institute. So far as the author knows, these are the first 

 adults reared m Europe. Placed in a Roux mcubator maintained 

 at an average temperature of 24°-25° C. [76°-77° F.] and fed daily 

 on guineapig and rabbit, they lived and reproduced satisfactorily. 

 The G. palpalis pupae, which came from the district of Sangalkam 

 near Rufisque, only produced two males. These small-sized but well- 

 built flies survived from the 17th January to 26th February. The 

 G. morsitans pupae came from the Lower Salum, near the borders of 

 British Gambia. They produced two males and six females. One 

 of the latter deposited four pupae and originated a strain which still 

 lasts, after a year's time, in surroundings kept at 1Q°-1T F. and at 50 

 to 55 per cent, of average humidity. Only twenty flies are now living, 

 as the mobilisation in August and September mterfered with the work
