SOLE or FOOT.

Sole of Poox. — From the crust we proceed to investigate 

 the sole of the foot. Figure 11 shews the ground surface of a 

 right fore foot : reference to the letters, and the annexed descrip- 

 tion will enable the reader to easily understand every part.

The priacipal matters to be noticed, are — the shape of the 

 sole, the varying thickness of the crust, and the perfect form of 

 the frog and bars. Observe also the greater swell of the crust 

 ( & ) on the rigJit, than upon the left side. As the crust is the 

 structure into which the nails are driven to fix on the shoe, the 

 reader will perceive, by referring to the engraving, where the 

 nails should be inserted. It will appear evident that the toe, 

 and the outer quarter of the foot, are the parts naturally best 

 adapted for such a purpose. 



I have compared, by measurement, the fore feet of a great 

 number of horses, with reference to the thickness of the crust ; 

 the difference of width between the right and left, or outer and 

 inner halves of the feet ; the angle of the crust ; the depth of 

 the crust at the toe, and at the heels ; the width of the sole ;
