514 HORSE-SHOES AND HORSESHOEING. 



To Osmer and Clark, therefore, belongs the merit of 

 having introduced this great innovation in the shape of 

 the shoe, and persistently pointed out the injury caused 

 by excessive paring and unscientific shoeing. To 

 Mr Clark is most certainly due the credit of having un- 

 mistakably asserted that the foot of the horse expands 

 and contracts in a lateral direction during progression. 

 In nearly every treatise published on the horse's foot, or 

 on shoeing, particularly on the continent, during the last 

 20 years, this notion has been erroneously ascribed to 

 Bracy Clark, who is always referred to as its originator.
