HORSESHOEING. 



continued rest in the stable, and frequently leads to a decided 

 change of form of the hoof. 



The disease is always accompanied with intense pain. It most 

 often affects both front feet, more rarely all four feet, or only one 

 foot. In the first case the tWo front feet are planted far in ad- 

 vance of the body, and the hind feet well forward under the 

 belly. When all four feet are affected, travelling is exceedingly 

 difficult, often impossible ; in this case there is nearly always a 

 high fever over the entire body. 



The seat of the disease is in the fleshy leaves about the toe, 

 more rarely upon the side walls and quarters. Depending upon 

 the intensity of the inflammation, the fleshy leaves are more or 

 less loosened from the horny leaves, as a result of which there 

 is a change of position of the os pedis, with a simultaneous sink- 

 ing of the coronet at the toe. This produces a change of form 

 of the hoof. The quarters become higher. Rings form upon 

 the wall, and their course is quite characteristic of the disease.

At the toe these rings are quite close to one another, but as they 

 pass back towards the quarters they gradually separate from one 

 another and recede from the coronary band (Figs. 123, 125, and 

 126).
