S52 DISEASES OF DOGS : THE EYES. 



Take— Red precipitate, in very fine powder, two scruples; 

 Spermaceti ointment, half an ounce. 



This ointment should be applied to the affected 

 eyelids morning and evening, by means of a camel- 

 hair pencil. If it does not readily yield to this 

 treatment, insert a seton, and give the alterative 

 ball (No. 35, p. 341). 



Mode of inserting a Seton. — The mode of in- 

 serting a seton, is to pass a skein of silk or cotton, 

 about six inches long, through the eye of a full 

 sized seton needle,* and besmear it well vi^ith com- 

 mon blistering salve. Having thus prepared the 

 instrument, let an assistant pucker up the skin of 

 the neck longitudinally, with the thumb and fin- 

 gers of each hand, and then force the needle through 

 the puckered skin, in the space between the assist- 

 ant's hands ; the opening in the skin should be an 

 inch and a half, or two inches, apart : the ends of 

 the skein should be tied when introduced. The 

 seton should be moved about a little every day to 

 and through the wound to irritate the parts, and 

 increase the discharge. 



I,* These may be procured at the Surgeons' Instrument- 

 Makers.
