Number 1 is unsightly. Moreover, it gives an unpleasant jar to the rider of the poor horse thus deformed; and few men, when they state this fact, ever think of what sensation that which jars the equestrian must occasion to the steed. It will produce lameness at first; but, this surmounted and the tumor fully formed, it causes no inconvenience beyond a loss of elasticity when in motion; and because it provokes no lameness, man says it is unattended by feeling. Figure 2 is a splint on the side of the leg. It also is unsightly, and produces a disagreeable sensation to the person in the saddle. Moreover, it is exposed to accidents. If the horse has high and close action, the tumor may be struck when the foot is being raised. Such a possibility is not altogether free from danger. The horse, having grazed the swelling, will often fall down as though it were shot. That circumstance warrants the supposition that these growths are not quite so devoid of sensibility as most horse owners are pleased to assert they are. The slight enlargement, opposite which stands figure 3, denotes a growth of small size. It may be of no great consequence, if it appear on a vacant part of the bone, or on a place over which no tendon passes; but it is of serious import, if situated beneath a tendon, as then it causes incurable lameness. Man having provoked these blemishes, Nature generally strives to remove the effects of his stupidity. She will smooth the top of the tumor by the interposition of cartilage and of ligament, that the skin may not be irritated when passing over these enlargements. She will also develop a false bursa on the top of each, thereby causing the integument to move with an approach to ease. Yet there are other sorts of splints which often are very serious affairs. That the reader may comprehend these, let him attend to the next engraving. 1--Represents a splint which has involved the bones of the knee, and which has left the horse only the joint formed by the lower end of the radius to progress with. This is a sad business. The action is injured for life; and death, or a cart, is the lot of the wretched animal so diseased. [Illustration: SPLINTS OF A SERIOUS KIND. 1. A splint involving the bones of the knee-joint. 2. A splint interfering with the action of the back sinews. 3. A small splint situated under the tendon of an extensor muscle. ] 2--Shows fine points of bone, so placed that they would impinge upon the suspensory ligament, if not upon the flexor tendons. Lameness, in its acutest form, would thereby be caused wherever the limb was bent. The lameness, probably, would last till death, as splints in this situation are rarely discovered during life.
