Kinds of Sutler es. 67 



2. In the twisted suture a needle is not used, but a strong 

 pin is run through each edge of the cut, and a thread or fine 

 Avire is twisted across the two protruding ends of the pin, so 

 that the edges of the wound are firmly held in place ; as seen 

 in Fig. 18. 



Fia. 18. — THE TWISTED SUTUBB. 



After a wound is closed with sutures, it should be dressed 

 with a plaster, ointment or a bandage, so as to prevent the 

 thread or pins from tearing out ; and it is proper to remove 

 them in four or five days, to prevent blemishing. 



OPEEATIONS ON THE TEETH. 



The teeth of horses require frequent attention at the 

 hands of the veterinarian or of the ow^ner, if he would keep 

 his animals in good condition. 



If the lower incisors become so long as to bruise, or 

 otherwise injure the bars or roof of the mouth, they must 

 be shortened with a rasp. 



The same instrument is required when it is found that 

 owing to the greater width of the upper row of the molars, 

 a ridge of unworn tooth material is presented on the outer 

 aspect of the upper, and on the inner side of the lower 

 teeth, leading the horse to wound his tongue in masticating, 

 and to grind his food.
