Trasbot strongly recommends a mixture of three parts of benzin, 

 and one part each of oil of cade and coal-tar. 



If we use one of the oily applications or a solution of tobacco for 

 sarcoptic mange, we should dress only one half of the body at a 

 time ; and the other half, a day or two afterwards. Paraffin oil 

 is apt to have an irritating effect on the skin, and by absorption 

 may give rise to symptoms of poisoning, which may also be set 

 up by the use of corrosive sublimate or mercurial ointment. At 

 the same time, it is such an effective parasiticide, and can be 

 so easily procured, that it is second to none as a basis for a 

 mange dressing. If, by irritating the part, the proportion of 

 paraffin oil be found to be too large, it may be lessened by adding 

 more common oil to it. The employment of corrosive sublimate and 

 mercurial ointment might be limited to cases of psoroptic or sym- 

 biotic mange, in which the surfaces treated are of much less extent 

 than in sarcoptic mange. Two or three days after the first appli- 

 cation, we may wash the skin as before, and repeat the dressing. 



We should not unnecessarily continue the applications or use 

 them too strong, lest we may set up an irritable condition of the 

 skin, which we may have difficulty in distinguishing from the 

 original complaint. Synibiotes require far less energetic measures 

 for their eradication than either of the two other kinds of mange 

 parasites. As the eggs and egg-laying females of the sarcoptes are 

 concealed in galleries underneath the scarf-skin ; the treatment of 

 this form of mange should be continued, off and on, for about a 

 fortnight, by which time we may expect that all the eggs will be 

 hatched, and the young ones destroyed on coming forth. 



As mange is solely due to the presence of a parasite, whose 

 attacks can in no way be modified by the internal administration
