168 DISEASES OF THE HOESE. 



starved, and severely worked horses in an exaggerated 

 form. Plethora and standing in the stable are also 

 fruitful causes of it, for, by standing still, the vessels 

 become inactive, enfeebled, and distended. It very 

 frequently shows itself in young horses, when first 

 brought into the stable, and put to hard work too 

 rapidly. 



The treatment must consist in first removing all 

 hair and then thoroughly cleansing the part with hot 

 soap and water. It should be rubbed dry, and dressed 

 with an astringent lotion, consisting of one scruple 

 of chloride of zinc and one ounce of laudanum in half 

 a pint of water. This should be repeated three times 

 daily, applying some glycerine after the last dressing 

 at night. 



The general habit must now be attended to, and the 

 supposed cause of the attack removed, whether it be 

 too much or too little exercise, plethora or debility, or 

 the presence of cold. 



Physic should rarely be given in any case, but when 

 depletion is necessary, the purpose is better served by 

 giving alteratives, such as sulphur, nitre, and black 

 antimony, of each half-an-ounce, given in bran and 

 linseed mash, every alternate day, and changing the 

 food to carrots, malt dust, &c. 



When debility is the cause, the tonic powders, con- 

 sisting of one ounce of bark and aniseed, with one 

 drachm of emetic tartar, given daily during alternate 

 weeks, with liberal diet, should be persevered in until 

 the desired effect takes place.
