 pp. 279-281. 



Ikaphthisol is said to be the best insecticide available against the 

 lice on horses. It is a white powder, which smells like cresol, but not 

 so strongly. Besides oxytoluol or cresyl alcohol, the other ingredients 

 are carbonate of magnesia, bolus alba, talc, crude cresol and sapa 

 medicatus. The powder only requires dusting on, the quantity per 

 horse being from 5 to 7 oz. and costing about 3d. The lice are killed 

 in a few minutes, hundreds being combed out 5-10 minutes after 

 application. In the case of very badly infested animals a second 

 application is advisable.

 Erkrankungen. [Sickness among live-stock caused by '• Kolum- 

 bacser gnats."] — Deutsche Tierdrztl. Wochenschr., Hannover, xxiv, 

 no. 27, 1st July 1916, pp. 247-248. 



At the end of April and during May swarms of gnats [Simulium] 

 appeared in some localities in south Hungary during a spell of calm 

 weather following prolonged winds. In the district under the author's 

 veterinary supervision 67 cattle, 1 donkey, 6 horses, 71 pigs and 10 

 sheep died and 24 cattle had to be slaughtered. When attacked by 

 the flies, the animals, especially cattle, take to flight unless they are 

 able to take refuge in neighbouring water or in the smoke of fires;. 

 The flies settle on the hairless parts in order to suck blood and their 

 bites are shortly followed by symptoms such as laboured breathing,, 

 a stumbling gait and rapid pulse, and painful swelhngs in the 

 loose-skinned portions (as beneath the neck). Animals attacked by 

 large numbers die in from one to two hours without signs of oedema. 

 Less severe cases are characterised by loss of appetite, abortion, 

 marked depression and blindness. The swellings go down in four 

 or five days after rubbing with spirits of camphor, but the blindness, 

 may be permanent. The animals w^hich died or w'ere slaughtered 

 showed serous infiltration of the subcutaneous tissue with ecchy- 

 mosis. Treatment consists in wiping off the flies with a rag, the- 

 internal administration of diluted alcohol and repeated rubbing with 

 spirits of camphor.

This article deals in popular form with the measures required tO' 

 protect domestic animals against various flies. Stalls and stables must 

 be cleaned at frequent intervals, their walls should be light coloured and 

 openings should be screened with wire gauze. The following solutions 

 are said to be effective repellents. Five per cent, cresyl, one per cent. 

 picric acid, ten per cent, boric acid, and ten per cent, saponin. These- 

 washes should be applied once daily.
