DIAGRAM OF AN INCISED WOUND.
The danger consequent upon an incised wound is ever measured by the extent of the hemorrhage. When large arteries are divided, that fact is easily told by the size and the force of the jets sent forth. A strong horse may, from that cause, be dead in ten minutes. To enforce the difference between a lacerated and an incised wound, the reader is reminded of those painful cases, frequently recorded in the newspapers, where a limb is by machinery torn from a poor man's body, and scarcely a drop of blood marks the deprivation; also of death by severing a throat, when sensation ceases ere the stream has flowed forth. The last is an incised, the first is a lacerated wound.
DIAGRAM OF AN ABRADED WOUND.
An abraded wound, in its mildest form, is simply a graze. The reader will, however, remember how acutely painful such accidents always are. The horse's sufferings are not highly estimated by the generality of people; nevertheless, an injury of this description is not to be despised, even when witnessed on the animal. A broken knee, as it generally is exhibited, is nothing more than an abrasion. An abraded wound may simply mean that the insensible outer covering of the skin has been injured; it may also imply that the soft structures beneath have been sundered. Wounds of this kind are not free from danger when of magnitude. Little blood may flow, but the cutis is the most sensitive structure of the entire body. A needle's point cannot enter any part of the skin without sensation warning the person of a puncture. In human operations, division of the skin, or separation of the cutis, is known to constitute the major portion of the patient's agony.
The suffering attendant on the latter class of injuries is increased by almost every abrasion forcing grit or dirt into the substance of the cutis. This, of course, is generally washed out. The torture accompanying a large abraded surface is, therefore, very great; and horses when suffering from accidents of such a nature sometimes sink from the irritation consequent upon the injury. When the animals survive, the roots of the hair too often have been destroyed, and a perpetual blemish is the result.
DIAGRAM OF A PUNCTURED WOUND.
The engraving supposes the soft parts to have been divided, in order to show the ragged nature and large extent of the injury, with the comparatively small opening by which this amount of harm is characterized.
