Veterinary notes for horse owners : a manual of horse medicine and surgery . orns occur frequently in the fore feet,they are rarely found in the hind ones; the reasons being thatthe latter are far less exposed to concussion than the former;their soles are, naturally, more arched, and, consequently, areless exposed to injury; the heels are stronger, and as a rule COKNS. 221 are not lowered so much in shoeing as the heels of the forefeet. The fact that corns occur much more frequently on theinner heel, than on the outer, is usually accounted for by thesupposition that more weight is thrown on the inner than on theouter side of the foot; but the general custom of shoeing horsesvery close on the inside heel, is, I think, much more to liability may also be influenced by the more perpendicularposition of the wall of the inside of the hoof, and by the factthat the wall of that side of the foot is weaker than that of theouter side. CAUSES AND PREVENTION.—The chief cause is a faultysystem of shoeing, by which pressure becomes applied to the Seat of cornBar. Seat of cornBar Fig 73.—Ground surface of horses foot. seat of corn. The common and pernicious practice of cuttingaway the bars, undoubtedly, disposes the foot to contract thisailment; for the wall at the heels, when it loses the supportafforded by the bars, is apt to bend inwards and to press onthe seat of corn. It sometimes happens that, when preparing the foot, the smith rasps down the wall at the heels without alsoreducing the horn over the seat of corn, which then bears thegreater part of the pressure, with the natural result of this , when the heels of the shoe are spriing,^ that is, whena space is left between them and the horny heels, grit andparticles of stone are apt to work in between the web of theshoe and the seat of corn, and, consequently, to hurt the latteron account of its being constantly hammered upon by the former,whenever the animal moves.
