Wounds or bruises of the coronet are known by the general 

 name of treads, because they come usually from being stepped 

 on. Treads are dangerous when they affect the extensor tendon, 

 or when they injure the joint between the coffin-bone and the 

 coronary-bone. A tread must be kept very clean, and infection 



must be very 

 carefully 

 guar d e d 

 against by the 

 use of antisep- 

 t i c dressings 

 - as iodoform, 

 calomel, o r 

 car b o 1 i z e d 

 vaseline. 



If the tread 

 is serious 

 enough to de- 

 stroy part of 

 the coronary 

 band, the 

 part of the 

 hoof that was 

 supplied b y 

 the destroyed 

 part fills in, in 

 an irregular 

 way, from the 



sides and from beneath, and a malformation called false quarter 

 results. 



A puncture is a wound to the foot, caused by a nail or 

 other sharp object being driven into the sensitive parts of the foot. 

 Any infection within the rim of the hoof, resulting in sup- 

 puration, forms an abscess that cannot drain downward. As
