Horses. i63 agents in causing the contraction of the heel; for, when the pressure is removed from their inner surfaces, they tend to assume their natural position, in virtue of their elasticity, and the pressure they exert upon the sensitive frog, forces the heel into its original Cartilaginous Apparatus of the Horse's Foot.

Bi-iefly, then, they may be said to expand, when the foot is on the â ground; aftd to assist contraction, when the weight which forces the sensitive frog upwards and outwards, is removed from the foot. Professor Williams, in short, holds that these lateral appendages act, as it were, as "elastic sides," preventing undue expansion of the soft parts of the coronet and heel. The term side-bone, we have said, denotes a bony or ossified â condition of the lateral cartilages. This condition is commonly met with in heavy draught horses, and is but rarely seen in the lighter breeds. It is almost always met with in the fore feet, though in rare instances it has been observed on the hind ones. In the latter situation, it is never known to occasion lameness. The lateral cartilages are of lesser size here, and, being of less functional importance, are consequently much less liable to become diseased. We may now proceed in the first place to examine the causes of this very common form of disease among our heavy draught horses. Some â¢authorities compute that over fifty per cent, of the heavy draught horses become affected with this disease by tlie time they have attained the age of six or seven years; but, according to our own computation, sixty per cent, is not an exaggerated estimate of
