BLEEDING 287 



together, care should be taken not to draw the skin 

 too much from the neck, otherwise blood will insinuate 

 itself between the skin and the muscles, and cause a 

 swelling (thrombus), which sometimes proves trouble- 

 some. The edges of the wound will heal in forty- 

 eight hours, but the pin should be allowed to remain 

 in the skin for about seven days. 



The jugular being the largest superficial vein, 

 and most readily got at, is generally selected to bleed 

 from. In local inflammation, blood may be taken 

 from any of the nearest superficial veins. For 

 example : in affections of the shoulder, fore leg, or 

 foot, the plate-vein may be used, which lies along the 

 inside of the arm, and runs up immediately in front of 

 it, towards the jugular vein. The disposition of this 

 vein will be seen at Plate vi, fig. 2, r, and the branches 

 of the other veins of this portion of the limb are 

 exhibited in the same figure. Where the hinder 

 extremity is affected, blood is sometimes taken from 

 the saphsena, or thigh-vein, which runs across the thigh. 

 The course of the different veins of this part will be 

 seen on referring to Plate vn, fig. 2. Where the 

 foot is at fault, blood may be taken from the coronet ; 

 or, what is better, from the very point of the toe, by 

 cutting down by means of a searcher at the union 

 between the crust and the sole until the blood flows. 

 Should it not do so freely, the discharge may be 

 increased by dipping the foot in warm water. Any 

 quantity of blood may be taken from this situation, 

 and its flow is easily stopped by putting a little tow in 

 the cut, and then placing the shoe slightly over it, to 

 prevent it from getting out. 



In inflammatory cases, the finger of the veterinarian 

 should never be off the artery during blood-letting, as 

 this will be a better indication of the quantity neces-
