 longer. The baldness disappears as a rule completely; if it re- 

 mains it is in ringworm on the face of the dog (Schindelka). 



Treatment. This is regulated according to the situation 

 and extension of the eruption. As a preliminary treatment, 

 except in the case of short-haired animals and where only quite 

 circumscribed and isolated spots occur, the affected animals 

 should be sheared ; but where only a few spots are present, the 

 hair may be pulled out with the forceps or cut away in the 

 affected region and its immediate neighborhood. Hard crusts 

 should be softened with equal parts of soft soap and lard, 

 whether the spots are localized or widespread; in case of an 

 extensive eruption creolin oil (1:20) is most suitable; in this 

 case the fore part of the animal may be anointed with the mix- 

 ture the first day and the hind part on the following day, and 

 the oil is left on for 2 to 4 days. The softened scabs may then 

 be scraped off or, in extensive cases, removed with fomenta- 

 tions or a bath. Sometimes the inunction must be repeated. 



The preparatory treatment is then followed by the admin- 

 istration of antiparasitic remedies which kill the fungi situated 

 on the surface of the skin and immediately underneath, and act 

 thus especially by hindering the further advancement of the 

 process. Anti-parasitics are employed preferably in the form 

 of ointments, for the fungi appear to l)e peculiarly susceptible 

 to fats and rancid oils (Pusch), and besides the resisting power 

 of the skin against fresh invasions is diminished by fomenta- 

 tions. Mercury preparations, as gray ointment, white and red 

 precipitate ointment (1:10-15), calomel ointment (1:4), cor- 

 rosive sublimate (1:200 alcohol or sublimate soap) are equally 

 effective, Init must not be used on cattle. In cattle and in the 

 other animals, salicylic ointment may be used to advantage, 

 also ointments of tar, naphthol, naphthalin or creosote (1:10) 

 as well as tar or naphthol with soft soap (aa) ; in dogs Peruvian 

 balsam may be used. In horses R. Frohner found Baranki's 

 ointment very effective which he had prepared for the first 

 inunction of 1 part of acidum nitricum fumans and 10 parts of 

 adeps lanaB anliydr., and for subsequent applications of 1 part 

 acid nitr. and 20 parts of lanoline. On the other hand Wagner 

 found cresol liniment to give the best results in young cattle 

 (Aqua cresolica, Sapo Kalinus ven., Spir. dil. aa), then creolin 

 soap or creolin ointment. If the eruption is very extensive 

 creolin baths may occasionally be used. In mild cases daily 

 painting with tincture of iodine (1 :l-5 alcohol) is frequently suc- 

 cessful. All these remedies should be applied not only to the 

 diseased parts of the skin but also to the neighboring parts. 



During treatment one should endeavor to prevent the ani- 

 mals from rubbing, consequently exercise in the open, going 

 out to pasture or in the yard is not to be allowed. Finally daily 

 cleaning of the animals should be discontinued. Drving of the
