draught horses, and, when it does occur, it is usually traceable to overwork, 

 or to injudicious shoeing. A severe tread, if neglected, may end in a quittor, 

 and should therefore receive .careful attention. If very slight, tread will 

 require no treatment beyond the application of a little carbolised oil (i in 40), 

 or of tincture of myrrh. If the injury be of a more serious nature, the wound 

 should be carefully cleaned with tepid water, and afterwards dresssed with 

 carbolised oil or carbolic acid lotion (i in 30). In those cases where "pus" 

 tends to form, the wound must be kept very clean, and the foot poulticed for 

 three or four days. Sometimes a little mild blistering ointment around the 

 wound will stimulate the part to healthy action, when the healing process is 

 unduly protracted. 



OVER-REACH. 



Ax over-reach is a wound upon the coronet of the fore foot, caused by 

 treading on the inner or outer edge of the toe of the hind foot. The injured 

 spot is generally situated immediately above the heels, and is often to be 

 attributed to careless riding or hunting over heavy countr)-. In horses 

 having a tendency to over-reaching, the toes of the hind shoes should be of 

 a square pattern, with side clips if necessary. In order to pi'event the 

 infliction of this injury, circular india-rubber guards are made, which pass 

 over the foot, and protect the seat of injury. In most instances, it will be 

 unnecessary to poultice the foot for over-reach ; but in severe cuts, this should 

 be done for several days. In simple cases, the wounds should be cleansed 

 thoroughly, and afterwards dressed daily by the application of a little 

 carbolised oil (i in 40). 



In most instances of over-reach under our notice, the animals were 

 hunters or thoroughbreds. In some instances the tendons at the back of 

 the heel are bruised or cut, and in such cases it will be well to rest the 

 animal, and apply a high-heeled shoe if necessary. In these cases the 

 wound should be well cleaned with tepid water, and carefully dressed with 

 carbolised oil and then bandaged. If there be no actual wounds, cooling 

 lotions (spirit i part, solution of subacetate of lead i part, water 8 parts), 

 bandaging, and rest will suffice. 



VILLITIS, OR INFLAMMATION OF THE CORONARY 



BAND. 



There are two diseases of the coronet to which we must allude, before 

 considering the nature and treatment of horn tumours. Villitis, or 

 inflammation of the coronary band, a disease generally met with in heavy 

 cart horses, but sometimes occurring also in more highly bred animals, is 

 manifested by a tender, hot, and swollen condition of the coronet. The horny 

 crust of the foot becomes harsh and brittle, owing to interference with the 

 secretory activity of this coronary band, which is tender on pressure. The
