 mange of the horse); the final cure can onlj be obtained by repeat- 

 ing the treatment at short intervals for weeks and even months. 



Mange is a very important disease from the standpoint of sani- 

 tary police regulation and commercial jurisprudence. 



1. It is considered as an epizootic disease by the sanitary police; 

 the German law of June 23, 1880, concerning epizootics includes 

 sarcoptic and psoroptic mange of horse, ass, mule, jennet, and 

 psoroptic mange of the sheep. 



2. Sheep mange is regarded as sufficient to set aside a contract 

 of sale in Bavaria, Wiirtemberg, Baden, Hesse, Hohenzollern, etc., 

 with a delay of fourteen days ; in Saxony the delay is extended to 

 fifteen days ; in the Duchy of Nassau to twenty-nine days. Mange 

 of the horse sets aside a contract of sale in Prussia, with a delay of 

 fourteen days, and in Saxony with fifteen days' delay. In this 

 latter province mange of the ox is also controlled by law with a 

 delay of fifteen days.

 gradually become extended ; the eruption rarely reaches the whole 

 surface of the body ; in most cases it remains located upon the 

 head, neck, and shoulders. 



Its other principal symptoms are : a continuous pruritus, which 

 is especially intense during the night and when the skin is over- 

 heated ; this pruritus forces the animals to scratch and rub them- 

 selves and to bite the diseased regions. When touched, rubbed, or 

 slightly scratched on these parts of the body the horse shows, by 

 manifestations not to be mistaken, the pleasant sensations which he 

 feels and the relief he experiences ; he stretches his neck and 

 head, bends the spinal column downward and turns up his upper 

 lip like the stallion when smelling at the mare. At the beginning, 

 the alterations of the skin consist of small pimples, on the surface
