 inner half of the web ( see Fig. 76). 



According as the contraction is confined to the inner or 

 outer heel, the saw-cuts, one or two in number, are placed 

 to the inner or outer side of the toe-clip. When the con- 

 traction is bilateral, the saw-cuts, one or more in number, 

 are placed on each side of the toe-clip. 



(d) Broucs. — This is one of the forms of so-called 

 'slipper' shoes (see Fig. 77). We have already indicated 

 that the shape of the bearing surface of the ordinary shoe 

 — by its ' seating ' or sloping from outside to inside — is

 .Broue this bearing is reversed, and the slope is from inside 

 to outside. In the original form of this shoe the slope to the 

 outside was continued completely round the shoe. Experi- 

 ence taught that the strain this enforced upon the junction 

 of the wall with the sole was injurious, and that the ' re- 

 versed seating,' if we may so term it. was best confined to 

 the hinder portions of the shoe's branches. 



The amount of slope should not be excessive- If it is 

 too rapid and too forcible an expansion takes place, and 

 pain and severe lameness results. Dollar gives the requisite
