ment (1 part of creosote in 20 jjarts of tar and soft soap aa, or 

 1.5 to 2 parts of creosote, 10 parts of soft soap, and 5 parts of 

 alcohol) may also be employed with very good results; with 

 these remedies half of the bodj^ may be rubbed alternately at 

 intervals of six days. With the creolin liniment, according to 

 Frohner (creolin and soft soap aa 1 part, alcohol 8 parts), one 

 side of the body may be rubbed on alternate days ; after 3 entire 

 rubbings a day of rest is given; repeat 3 to 4 times. The oc- 

 currence of somewhat severe irritation of the skin may be 

 avoided by reducing- the strength of the applications with al- 

 cohol (5 to 7 parts) and any irritation that may already be 

 present is allayed by applying any bland oil. The anointing 

 of the whole surface of the body at one time with creolin lini- 

 ment may cause the immediate death of the animal (Pr. Vb. 

 1907). By daily applications with a brush of cresol liniment 

 (aqua cresolica 5 parts, soft soap and alcohol aa 2.5 parts) and 

 by a thorough cleansing washing on the sixth day, the dermato- 

 phagus scab is cured after two of these operations, but the 

 more severe forms of sarcoptic scab necessitate 4 or 5 repeti- 

 tions (Schlampp). Effective results are also obtained with 

 5% tobacco decoction, while Schindelka recommends sulphur 

 ointment (flor. sulph. 18 gm., potassium carbon., 10 gin., adeps 

 suill. 120 gm.), 5% creolin (styrax and glycerine aa). The em- 

 ployment of naphthol is not without danger. 



The dermatophagus mange is healed in a short time by 

 using 10% carbolic or creolin glycerine, by carbolic soap or tar 

 ointment. 



other parasiticides are: corrosive sublimate (in 2% solution as a wash; only in 

 mild forms and even then not always effective) ; benzine (5 parts with 10 parts of 

 water), petroleum (with oil aa) ; both these remedies cause inflammation in the 

 skin, moreover the petroleum has only a weak effect. Styrax as well as balsam of 

 Peru (pure or with 3 to 5 parts alcohol) are only suitable for applications to small 

 skin surfaces on account of their high price. Arsenic (1% solution in vinegar or as 

 Viborg's bath; Acid, arsenicos.). Potass, carbon, aa 1 part. Aqua, Acetum comm., 

 aa 100 parts; of the solution at most 500 gm. at one time), potassium sulphide 

 (with 5 to 10 parts of water), etc. Fiirthmaier treated horse mange successfully 

 with a formalin soap solution in the following way: 100 grammes of soft soap are 

 dissolved by warming in 750 gm. of water, after cooling, the fluid is decanted, and 

 after the addition of 100 gm. of formalin (40% formaldehyde) it is filled up to 

 one liter with lukewarm water; applied at first only to the diseased places but 

 afterwards also to the healthy parts of the body; repetition after 5 to 6 days; in 

 obstinate scab 3 to 4 times, but the last two applications are to be made at intervals 

 of 8 to 10 days; after rubbing in there was transient unrest. Recently in Ger- 

 many a 25% watery solution of therosot which contains mercury has been largely 

 used (apply to a third of the body at a time and afterwards blanket the animal; 

 repeat after weekly pauses). Washing with a 4% bacillol solution has caused 

 transitory symptoms of poisoning and falling out of the hair (Hennig). 



During the treatment good and plentiful food must be given 

 to the horses, and they must be kept in dry, clean and moderate- 

 ly warm quarters. Since in spite of careful treatment single 

 mites may remain alive, it is well to watch the animals for some 

 time, and to resume treatment immediately on the occurrence 

 of suspicious s^Tiiptoms. In this case less heroic remedies may 

 be employed successfully. It is especially necessary to watch
