SIMPLE CUT WOUNDS. 



When only small blood vessels are cut quite through 

 they draw back, and the blood soon ceases to flow. 



When wounds made by sharp instruments are consid 

 erable, they are generally attended by a flow of blood. 

 If the effusion be great, and if, from its florid color, and 

 flowing in jets, it appears to proceed from an artery, it 

 must be quickly stopped. If there be no means of ap- 

 plying pressure on the course of the artery, between the 

 heart and the wound, the finger may be introduced into 

 the wound, and pressed on the artery, to stop the blood 

 till the artery can be taken up, or some means used to 

 stop it. 



An instrument called tenaculum, which is a sharp, 

 pointed hook, is the most convenient for taking up an 

 artery to be tied. A double thread being waxed, and 

 an open knot made on it, it is put over the instrument. 

 The artery is then laid hold of by the point, and drawn 

 out a little, the open knot is slipped over it, and firmly 

 drawn, and the ends of the thread allowed to hang from 

 the wound. Veins may be secured in the same way. 



If a blood vessel cannot be tied, and no means used 

 to stop the effusion, fold a piece of linen rag to a quarter 

 of an inch in thickness, and apply it to the orifice of the 

 Dlood vessel, and press it with the finger, first wetting 

 the rag in strong alum-water. [See directions to stop 

 blood.] 



The cure of wounds is effected by adhesion or suppu- 

 ration. When the sides of a fresh wound are brought into 

 accwrate contact, and kept together, they adhere very soon, 

 and the wound soon heals, with little or no trciuble. 

 This is called healing by the first intention. The flesh 

 of horses does not unite so readily by the first iiiteiition 

 as that of other animals, and the wound is more likely 

 to heal by suppuration. 



PUNCTURED WOUNDS. 



These are made by pointed instruments, splinters ol 

 wood, bites, &c. They are more dangerous than cui 

 wounds, as they excite more inflammation, and it is difli
