1, 2, 3, show the thickness of wall and sole full size 

 at poinfs indicated. The inner or soft parts of the wall 

 (not represented as clearly by the engraver as it should 

 be) represents about one-eighth of an inch less in thickness 

 than shown in 1 and 2. The outlines of the hard part, as 

 originally drawn, being cut away by the engraver, show 

 the wall on this account thicker than it should be. No. 3 

 was drawn to show the thickness of hard fiber with the 

 soft or laminated part omitted, which will give a good idea 

 of the small amount of horn there is in an average light 

 foot to nail to, and how easy it is to break and weaken it 

 seriously by nailing deeply, rasping and cutting away reck- 

 lessly, as shown by Fig. 411. The notches between the 

 sole and wall indicate the degree to which the soft horn at 

 this point had been macerated or dissolved by the action 

 of moisture to which the hoof had been subjected for two 

 weeks.
