Causes. — The causes are either long-continued leaving of 

 one-half of the wall too high, or the use of shoes shaped for 

 normal feet upon hoofs of the base-wide position. 



The principal part of the treatment is the proper dressing 

 of the hoof. The wall which is bent out at the middle and 

 drawn in at the plantar border is, as a rulcj too high and too 

 near the centre of tKe foot (too narrow) ; the opposite wall, 

 on the contrary, is too low 

 and too far from the centre 

 of the foot (too wide). This 

 explains the manner in which 

 the hoof should be cut down 

 and rasped. The shoe must 

 be laid out as far as possible 

 towards the side which is 

 too high and narrow. A 

 straight edge placed against 

 the high wall touches it only 

 at its middle. The distance 

 of this line from the lower 

 edge of the wall shows us how 

 far the surface of support — 

 namely, the shoe — should be 



set out beyond the horn. If a crooked right fore-hoof of the base-wide

showing that the wall is concave. The distance of the mid- 

 dle of this wall from the straight edge shows us how 

 much too wide this half of the wall is at its plantar 

 border, and how much of the outer surface of the wall at its 

 plantar border should be removed with the rasp. The restora- 

 tion of a crooked hoof to its normal form requires several
