BLEEDING. 509 



The hair is cut off in a small patch close to the wind-pipe ; 

 then, tying a string tightly round the neck, the vein will be 

 felt to rise on the side next the head, and then the lancet 

 must be introduced with some little force, cutting out again so 

 as to make the opening large enough inside to allow of the 

 blood escaping. When enough blood has been taken, the string 

 is taken off, a pin is introduced through and across the lips of 

 the wound, and some tow or thread woimd round the ends ; 

 after which the point is cut off, and the whole is left for three 

 or four days, when the pin may be safely withdrawn, leaving 

 the tow to fall off. If the neck is too fat, a vein on the inside 

 of the fore arm may be opened. To insert a seton, all that 

 is necessary is to take any large needle with an eye (a seton 

 needle is made on purpose), then, lifting up a fold of skin, a 

 knife or lancet is passed through it, and on its withdrawal the 

 needle armed with the tape follows, after which the two ends 

 of the tape are tied with a common knot, and in that way it is 

 securely kept in. In bad cases of brain mischief, when there 

 is a necessity for immediate relief by counter-irritation, a small 

 red-hot poker is passed through the opening made by the knife 

 before the introduction of the tape, which need not then be 

 covered with blistering ointment, as is required in .ordinary cases. 

 The closing of wounds, and the application of the muzzle, have 

 been already described.
