The food should be good — if possible, green and succulent; and It 

 wjtl be found advantageous to take the chill from wkter given him, if the 

 weather is at all cold. If the appetite is bad, place gi-uel in the manger, 

 so thi't he may use it instead of water till stronger food is relished. 



If it is Summer, or Spring is sufficiently advanced to be mild, he maj 

 be turned to pasture ; but in any event, he should be allowed to rest 

 during treatment. 



In the more confirmed cases a speedy cure is not to be expected ; but

 No. 11, will bring the patient round in time. 



In very obstinate cases, occasionally anoint those parts where the

VII. Mange. 



Causes. — This is sometimes brought about by the same causes as 

 surfeit ; or rather, it is indeed but an advanced or chronic stage of that 

 disease ; though in some cases of the same kind, it is of a much more 

 serious character in itself, and highly contagious. 



When not a mere secondary stage of neglected surfeit, its immediate 

 cause is a parasite — the acarus — bred in the skin of the animal when 

 subjected to dirt and filth, and debilitated by hard living and ill usage, 

 or by total neglect and lack of food. The acarus produces mange in the 

 horse in the same manner as the human parasite produces itch in man ; 

 but it is of a different species, and frequently so large as to be visible 

 to the naked eye. 



Neglect, starvation, and accumulated filth having induced a depraved 

 state of the digestive apparatus, with which the skin sympathises, and 

 the insect once having obtained a lodgment, the horse, unless promptly 

 taken iu hand, soon becomes a loathsome object, and dies. 



The disease once contracted in this way, may be communicated to even 

 Bound animals, in good condition ; in fact, the great majority of cases 

 ire thus contracted, as comparatively few animals are so utterly neglected
