ACCIDENTS AND OPERATIONS. 



bodies, as the teeth of the dog, tearing rather than 

 cutting the JBesh. 



When a sheep has received any of these injuries, the 

 following rules ought to be attended to, and in the order 

 here recommended : — 



1st. Arrest the bleeding, if profuse, and likely to en- 

 danger life. 



2d, Clip away the wool for a few inches around the 

 injured part. 



3d. Remove dirt or other foreign body from the 

 wound. 



4th. Bring the separated parts as nearly together as 

 circumstances will at the moment permit, and retain 

 them there by suitable apparatus. 



(106.) To stop Bleeding. Bleeding will, if no large 

 arteries are divided, cease on the free exposure of the 

 surface for a few minutes to the air ; but when a large 

 vessel has been cut, more determined means must be 

 had recourse to. Pressure on the bleeding surface 

 and its neighbourhood will in many cases succeed, but 

 this or any similar method is far inferior to that of 

 securing the open vessel by a thread. To accomplish 

 this, the mouth of the vein or artery must be slightly 

 drawn out from the contiguous surface, by means of a 

 small hook, called by surgeons a tenaculum, and easily 

 procured from any blacksmith. While the mouth of 

 the vessel is thus held exposed, an assistant must sur- 

 round it with a noose of thread, which, on being secured 

 with a double knot, will effectually close it. The 

 thread ought to be of white silk, though any undyed 

 thread, which is firm, round, and capable of standing a 

 } ull, will answer the purpose. Care must be taken to
