Sarcoptic Scabies in Camel and Dromedary. 1 99 



a few weeks it is thickened, hard and painful, and is filled by a 

 yellowish, granular, foul debris in which the acari are found in 

 abundance. The ears now lop habitually and their interior, in- 

 cluding the lining membrane of the canal, is raw, swollen and 

 sore. The appetite fails, emaciation sets in, diarrhoea, abortion, 

 failure to breed, and in some cases drowsiness, vertigo, paralysis, 

 epilepsy and torticollis appear. In these cases the middle or inter- 

 nal ear may have been invaded if not by the acari yet by the ex- 

 tending inflammation. The vertigo is to be referred to the semi- 

 circular canals and the epilepsy to the reflex irritation from the 

 seat of irritation, like that which Brown-Sequard induced in muti- 

 lated Guinea-pigs. 



Treatment. Wash out the ear with castile soap and warm 

 water, then fill the annular cartilage and smear the concha with 

 a mixture in equal parts of olive oil and benzine and repeat the 

 application daily. A 2 per cent, solution of carbolic acid in 

 glycerine does well and is somewhat more permanent, as is a 

 similar solution of oil of tar or cade oil. A solution of tobacco or 

 a sulphur ointment is effective and devoid of irritant properties. 



The usual methods of purifying the hutch and surroundings 

 must be resorted to. Again horses with psoroptic mange must 

 be carefully excluded and the places where they have been, their 

 harness and other belongings must be treated. Whether the 

 psoroptes derived from the horse can live indefinitely in the ear of 

 the rabbit or not, it is certain that constant accessions of the para- 

 site will keep up the affection continuously in the rodent.
