SHOEING. 



of a form of shoe devised and largely used by him with great 

 success, the form of which can be well understood hy them. The 

 object to be attained is, where there is a want of mobility, or 

 much soreness and inflammation, to so form and a<lj ust the shoe 

 that the foot will partly roll upon the ground and relieve the 

 strain. This form of shoe has been patented by him. To use Mr. 

 Roburg's words, " This shoe, by allowing the foot to roll upon the 

 ground, gives the foot the advantage of an extra joint, and to that 



degree relieves the strain or 

 want of mobility, which 

 causes lameness or sore- 

 ness." Consequently it not 

 only enables the horse to 

 travel easier, but aids in

 closely and is remarkably successful. More special reference will 

 be made to this in Navicular-joint Lameness. 



This principle has long been in vogue in France. I give an 

 illustration from Laf osse, showing a side view of the hoof fitted for 

 the shoe ; also a specimen of the French shoe. The principle is 

 to turn up the shoe at the heel and toe about the thickness of the 

 iron. Mr. Roburg's shoe differs essentially from this, in that he 

 gives a curvature side-ways as well as with the length of the foot. 

 What he terms his "best model of shoe," and which is the most 

 unusual, is Fig. 525, which is nothing more than a thin plate 

 hammered into a i-ounded or bowl shape, the exact proportions of
