 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 unmistakably 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.
