MLx well with a gentle heat. Allow it to remain on the skin for tw« 

 or three days, and then wash off with strong soap and water. 



Tar ointment, (equal quantities of tar and lard well mixed with gentle 

 heat), is an excellent external application, and may be used when No. 22 

 is difficult to procure. 



XVI. Bat Tails. 



Causes. — Simple tetter, as also mallenders and sallenders, is sometimes 

 allowed through neglect to become obstinate ; the skin thickens ; ugly 

 cracks are formed, from which flows in abundance a sort of purulent 

 half-Avatery fluid ; upon the thickened portion of the skin the scabs 

 increase, growing up into somewhat perpendicular layers, and the hairs 

 grooving from these are glued together by the exuding matter. Such 

 bunches of matted hair are called, by reason of their appearance, "rat 

 tails." 



The disease seems occasionally to be produced outright, without the 

 supervention of an}^ other known disorder, by much exposure to wet 

 gi'ound of a chalky or loamy nature, or to sticky mud. 



How to know it. — It appears chiefly upon the legs, one or all of 

 which may be affected at the same time ; but the hairs of the tail, 

 especially near the root of the tail, are often found in the condition 

 described, and for a like reason. Tetter, ringworm, or some other dis- 

 order produces itching ; the horse rubs the part till it becomes raw ; 

 matter exudes at length, and the hair is matted in bunches along the 

 Mpper portion of the tail bone, as shown in the figure exhibiting external 

 ^nanifestations of disease. 



If resulting from either neglected tetter, no matter what its position, 

 or from mallenders and sallenders, it is accompanied by itchiness ; but 

 this is generally less severe than is the case with these disorders in their 

 simple form. When the disease is fully developed, the appearance of 

 the bunches of hair upon the parts is a sufficient indication. 



What to do — As in simple tetter, attention must be directed to estab- 

 lishino; a good condition of the bowels ; and to this end a purgative may 

 be given — especially if there is any indication of constipation and 

 general feverishness. The food must be regulated by the necessity of 

 keeping down all inflammatory symptoms. Make a tonic powder aa 

 'ollows : 



No. 23. 12 Oz. sulphur, 



1 Dr. arsenic, 

 1 Oz. bruised coriander seed. 



Divide into twelve parts and give one in the food night and morning.
