DISEASES OF THE SKIN. 313 



len, the parts are irritable and tender; the flexures of the knees 

 and hocks develop cracks, and occasionally a serous fluid exudes 

 therefrom; these conditions are described commonly as mallex- 

 DERS and SAivLENDERS; under these circumstances constitutional 

 symptoms are developed, as evidenced by an elevation of 

 internal temperature and an abnormally rapid pulse, and until 

 these febrile sj^raptoms are relieved the local manifestations 

 show no signs of abatement. 



Treatment. — Aconite 3X when brought on through cold, chill 

 and wet; when temperature is elevated; the skin dry and hot, at- 

 tended with some irritation and considerable burning; in the early 

 stages. 



Rhus toxicodendron 3X for itching and burning, going on to 

 vesicular eruptions; and b}^ means of external application of same, 

 consisting of one part mother tincture, two parts of glj^cerine and 

 nine parts of water, gently dabbed on with a sponge and the oper- 

 ation repeated night and morning. 



Graphites 3X for cracked heels, mai^i^enders and sai^len- 

 DERS when the surrounding parts are dry and harsh and the 

 cracks exude an excoriating discharge. 



Callendida (-J one part, glycerine two parts and water three parts, 

 to be locally applied to cracked heels, and the cracks in Mallen- 

 DERS and Sali^enders; to be applied to the affected parts three 

 or four times a day with a sponge. 



Urticaria is a form of skin disease not infrequently seen in the 

 horse, consisting of various shaped swellings that form rapidl}- 

 over any part of the body; the swellings var}' in size from that of 

 a pea to a walnut, having rather flat surfaces; the eruption is not 

 unlike the wheals formed through the sting of a nettle, hence the 

 common designation NETTLE rash; it is accompanied by a ting- 

 ling irritation which causes the animal to bite and rub it-self; it is 

 considered to arise as the cause of some stomach derangement; 

 and being very capricious, sometimes departs as rapidly as it 

 came; in tho.se cases, however, that last on and demand treat- 

 ment it is not unusual to find a very fine outer layer of the skin 

 peeling off after the febrile symptoms are abated, and following 

 upon this the hair falls out in patches. 



Treatment. — Apis 3X in simple cases due to a slight chill or 

 exposure in the burning hot sun.
