DISEASES OF THE EAR. 539 



PROTRUSION OF THE EYES. 



This frequently occurs from fighting. If the ball is not in- 

 jured and the eye is warm, showing that the circulation is not 

 cut oif, it may be put in place. 



Treatment. — The eyeball and orbit should be wiped with a 



silk handkerchief, and immediately replaced within the socket. 



When handling the eye, the fingers should be dipped in warm 



water or olive oil. In replacing the eye, it must be done gently. 



A firm pressure must be brought to bear, and the pressure should 



be changed from one part to the other, in order to replace it in 



the socket. A little oil may be placed on the inside of the lids. 



If it is best to remove the eye, a needle with a thread may be 



passed through it; then draw it out as far as possible, and cut off 



close to the lids. The bleeding will soon cease and the lids close 



perfectly. 



FISTULA LACHRYMALIS. 



The lachrymal duct is a small canal leading from the internal 

 angle of the eye to the nostrils, and is the passage through which 

 the tears escape. This duct may become closed by inflammation 

 of the mucous membrane lining the nasal chamber, by fungus 

 growths, etc. The canal when thus obstructed forms a fistulous 

 opening, just above the internal canthus. 



Treatment. — An effort should be made to clean out the canal 



by a suitable syringe. A small silver slide should be placed in 



the canal to keep it open and to direct the tears through the 



natural channel. The dog nuist be confined so that he cannot 



scratch the eye. 



WEAK EYES. 



Some breeds of dogs have naturally weak eyes. The eye in 

 such cases may be strengthened by the use of vinegar, one ounce; 

 laudanum, one scruple; water, six ounces. Sulphate, of zinc, one 

 scruple; water, six ounces, is another good remedy. When a 

 white film remains on the eye after acute inflammation has sub- 

 sided, nitrate of silver, one scniple ; water, six ounces, should le 

 dropped into the eye.
