MANGE.

Delafond and Bourguignon, and more recently Johne/ have 

 detected sar Coptic mange upon the wild felines (lion, leopard). It 

 was not produced by Sarcoptes minor but by Sarcoptes scabiei. At 

 the beginning they observed circumscribed psoric centres dissemi- 

 nated on the chest, belly, back, etc. The mange gradually became 

 generalized ; the whole body was covered with squamse, scabs, and 

 depilated spots.. The animals fell away rapidly, lost their appetite, 

 and succumbed within a variable time. Aspersion with Zundel's 

 anti-psoric bath has produced fatal poisonings (carbolic acid poison- 

 ing). Johne has obtained successful results by proceeding in the 

 following manner : the animals, kept in the narrow cage, were 

 sprinkled with a solution of balsam of Peru (balsam 1 part, alcohol 

 3 parts), then they were rubbed vigorously by means of brushes 

 fastened to loug iron haudles. These manœuvres, which were 

 repeated five times at intervals of eight to ten days, produced an 

 entire cure. 



Uar mange of the cat is produced by Symbiotes (S. auricularum, 

 var. cati). Affected animals shake the head, carry it inclined to 

 one side, and show symptoms of otorrhea. We have obtained good 

 results in the treatment of mange by using balsam of Peru mixed 

 with an equal quantity of glycerin. The external auditory meatus 

 must be thoroughly cleansed before injecting the remedy. 



h. Mange of the Rabbit. 



1. Sarcoptic mange. This is produced by the Sarcoptes minor 

 and is similar to mange of the cat, it affects the head in preference 

 (nose, lips, forehead), where it produces squamse and scabs, falling 

 out of the hair, thickening of the skin, itching, etc. The extremi- 

 ties are quite frequently affected at the same time as the head. 

 When it becomes generalized, the subjects grow rapidly emaciated 

 and die. It is advisable to use balsam of Peru or sulphur ointment 

 frictions as in the cat. 



2. Ear mange is produced by Symbiotes and Psoroptes cuniculi. 

 It frequently consists of an intense inflammation of the integument 

 of the external auditory meatus and is manifested by the formation 

 of thick crusts of brownish-yellow color, which dry, slit, and render 

 the concha very rigid at times. It may be complicated by altera- 

 tions of the middle ear ; in some instances the psoroptes invade the 

 whole surface of the body (Ziirn).
