104 DISEASES OF THE HOESE. 



where the coffin bone is let down upon the sole, and causes 

 its descent or convexity. 



Treatment. This is merely palliative and is to be done 

 by placing a shoe upon the foot that Avill insure and pro- 

 tect the sole from the ground. 



(12.) Thrush. — A diseased condition of the sensitive 

 frog of the foot, and from which a stinking fluid is dis- 

 charged, which is familiar to every person who is among 

 horses. 



Causes. Too much moisture to the foot, as from animals 

 standing in their own excreta, or from wet stabling, the 

 frog becoming perverted, and deteriorating, and secreting, or 

 discharging a blackish color, and otherwise nasty fluid. It 

 sometimes accompanies navicular disease. 



Prevention. Dry stabling, a stall having sufficient in- 

 clination or drainage to carry ofi* the fluids. Cleaning the 

 stables regularly. 



Treatment. A few drops of muriatic acid forced into the 

 centre of the frog once a day, for a few days. Keep the 

 stable and stalls dry and clean. A few doses of the sul- 

 phite of soda in half ounce doses, once a day, for a few 

 days, will do good by its alterative and puritive effiscts 

 upon the system. 



(13.) Tread. — This is, as its name indicates, a contused 

 bruise inflicted on the coronet or immediately above the 

 hoof by a tramp of the sho.e on another foot, or even by 

 another horse. Keep the wound clean, and apply the 

 tincture of myrrh and aloes daily. 



(14.) QuiTTOR. — This is a serious and painful disease 

 of the foot, of the same nature as poll-evil and fistula in 

 the shoulder; it is known by a large swelling around or 

 above the hoof, or where the hair joins the hoof, which 

 soon breaks and discharges pus.
