outer margin, and running only partially through the 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) Broue's. — 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 sometimes a

cause of contraction. In the * slipper ' of Brou^ 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 con- 

 tinued completely round the shoe. Experience taught that 

 the strain this enforced upon the junction of the wall with the 

 sole was injurious, andjthat the ' reversed 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
