HORSESHOEING.

The wall at the toe is sunken in just under the coronet ; its 

 lower part, on the contrary, is thrust forward. Later, the vMte 

 line becomes pathologically widened. The horn of the white line 

 is dry, crumbhng, and easily broken down, so that a break in 

 continuity (crack) is apt to occur between the wall and sole, and 

 lead to the formation of a hollow wall (^" seedy toe"). Where the 

 inflammation is moderate and is not repeated, healing usually 

 takes place and the horn grows down regularly and in normal 

 direction from the coronet. However, a rather brittle condition 

 of the horn remains permanently. If, on the contrary, the in-

flammation was very severe or repeated several times, the horny 

 sole becomes flat just in front of the point of the frog as a result 

 of the sinking of the os pedis, or it may even drop below the level 

 of the wall (full hoof, dropped sole). Indeed, it even happens at 

 times that the toe of the os pedis perforates the horny sole just 

 in front of the point of the frog. The wall at the toe, which was 

 previously but little altered in form, is now thrust prominently 

 forward. 



The inflammation of the pododerm may under certain condi- 

 tions and by skilful veterinary treatment be removed, so that 

 the characteristic changes of form and quality of the hoof will 

 not occur. But if this is not accomplished, as is often the case, 

 the disease will be obstinate, and permanent morbid changes of 

 the horn capsule take place.
