T45 



stables, or in straw yards, are liable to have this disease. 

 Among its first symptoms is a discharge of a fetid muco- 

 purulent fluid from the cleft of the frog, which gradually 

 extends to the neighboring parts, and if neglected may in- 

 volve the whole foot. This condition produces lameness, 

 and, of course, constitutes unsoundness. 



Trealment, — Carefully remove the diseased horn and 

 thoroughly clean out the excavation with a drachm of car- 

 bolic acid, to which must be added one ounce of water. 

 After this the following remedy may be used : 



Calomel _ _ _ Four drachms. 



Glycerine _ _ - Two ounces. 



This mixture must be put on a pledget of oakum and in- 

 serted into the cleft of the frog. Outside this a bandage 

 with some wood tar will do good service, and keep the feet 

 scrupulously clean. 



CANKER 



Is usually a more extensive or aggravated form of Thrush ; 

 it consists in a degenerate or depraved condition of that por- 

 tion of the sensitive foot which secretes the horny frog and 

 sole, which, instead of forming healthy horn, produces a 

 fungous growth of soft, spongy substance, covered with fetid 

 acrid bloody serum. This perverted secretion soon pervades 

 the whole sole, and ultimately extends to the entire secret- 

 ing surface of the foot. 



The same cause that produces Thrush induces this dis- 

 ease, and therefore the same remedies will do equally well. 

 The treatment recommended for Thrush, of calomel and 

 glycerine, is almost the best known. 



CONTRACTION OF THE FOOT. GROGGINESS. NAVICU- 

 LAR DISEASE. 



This disease is first excited by a strain of the perforans 

 tendon at the point where it passes over the navicular bone.
