In 1915 a number of deaths were again caused by SimuUum reptans 

 among cattle in the lowlands of the Leine from 22nd to 25th April 

 [see this Review, Ser. B, ii, p. 146]. Features of the present outbreak 

 are the great number of deaths and the presence of infection in localities 

 seven or more miles from the banks of the Leine. The latter is due to 

 SimuUum infestation of the streams flowing into the Leine, to weather 

 conditions favourable to the fly and to a strong east wind immediately 

 subsequent to the emergence of large numbers.

 Hannover, xxiv, no. 21, 20th May 1916, pp. 194-195. 



In treating mange in army horses it is important to decide whether 

 the animals must be shaven entirely or only in the affected spots, and 

 also whether the mites regularly migrate to preferred places or settle 

 direct on the infected spots. The author's experiments with two 

 horses resulted in the following conclusions : — (1) The incubation 

 period lasted 17 and 24 days ; it is shorter in the long winter hair 

 and longer when the coat is shorn. (2) The mites find more favourable 

 conditions in the long winter hair. They settle at the infected spot 

 and spread from it. These do not appear to be preferred spots in the 

 sense that the mites migrate to them from the infected spot and then 

 burrow.

The following liniment is said to give good results in the treatment 

 of sarcoptic mange : Turpentine, 1:4; linseed oil, 1:4; flowers of 

 sulphur, 6 lb. per 10 gallons ; tartar depurat, 3 lb. per 10 gallons. 

 Preparatory treatment consists in shearing the horse and in softening
