each of Epsom and common salt in 4 to 6 quarts warm water, 

 followed by free access to pure drinking water may suffice. If 

 needful a continuance of the same in smaller doses may be re- 

 quired. In indigestions saline, or in the horse aloetic, or in the 

 dog oleaginous laxatives with nux vomica or other bitters may be 

 used. Other tonics, like iron, arsenic, or echinacea may follow. 

 Where there is persistent intestinal fermentation, antiseptices may 

 be valuable : hjrposulphite of soda, calcium sulphide, naphthol, 

 creolin, or sodium salicylate. In hepatic disorder calomel may 

 prove useful. Where no definite internal disorder can be made 

 out, the nervous irritability may be counteracted by a course of 

 bromides. 



I/Ocal remedies are chiefly in the line of quieting nervous ex- 

 citement. I/Otions of carbolic acid (i : 100), thymol (i : 100),

 as examples. When a mucosa is implicated a cocaine (6 : 100), 

 or morphine solution may be tried, and balsam of peru, borax, 

 boric acid and chloral, have their advocates. 



DERMATITIS. 



Under this head may be included a class of inflammations of the 

 skin, due mainly or entirely to external causes, not essentially 

 parasitic, and attended by distinct eruptions (papukr, vesicular, 

 pustular, etc. Many of these are but an advance beyond the simple 

 erythematous inflammation, and coincide with it, the one condition 

 being present at one part of the diseased area, and the more ad- 

 vanced and severe lesions at another part. Bearing in mind the 

 frequency of this connection, it will be unnecessary to dwell at 

 length on this class of affections. 



Dermatitis Traumatica. Dermatitis from Mechanical 

 Injury. Besides the irritant factors already named as causing 

 traumatic erythema, we must here recognize contusions, over- 

 reaching, treads, interfering, bruising and chafing by harness, 

 girths, circingles, hobbles, ropes, traces, twists, and blows with 

 whip, club, chain or rope. Here the source of injury must be re-
