colodion dries quickly, and then after dry, I put a second coat on top of 

 the first one.

 Eye Iritis, or Inflammation of the Iris, is sometimes seen in dogs. The 



iris being the membrane that gives the color to the eye, in the center of 



which is the pupil. Deep-seated inflammation is usually the cause, or by 



direct violence. Symptoms are contraction of the pupil, which does not 



have the same power as usual of contracting and dilating to regulate the 



amount of light to be admitted; tears flow over lid, light is avoided, and 



the eye is bloodshot. If the inflammation increases and is prolonged, the 



usual termination would be suppuration (formation of matter), and the 



loss of sight. First place the dog in a darkened kennel or room, apply hot 



fomentations continuously to the eye, and introduce sulphate of atropine 



into the organ. Discs of sulphate of atropine you can get at your druggist's, 



with instructions how to use. 



Eyelashes, Turned in. — This occurs occasionally, the eyelash may grow 

 across the pupil, interfering with the dog's comfort and vision. In ordi- 

 nary cases simply clipping with the scissors will do, but sometimes excision 

 and cauterization of the part is necessary. Either of my Eye Lotions to be 

 used if inflammation is present. 



Haw, Enlargement of. — The haw, or third eyelid, as it is sometimes 

 called, is a fold of membrane situated at the inner corner of the eye, capable 

 of expansion, and is used to sweep across the globe of the eye to cleanse it 

 from flies, dirt or other foreign bodies that have blown in. This membrane, 

 from constitutional causes, from blows or irritation from extraneous matter 

 lodged in the eye, becomes inflamed and enlarged, which interferes with the 

 sight, preventing the eyelids from closing. My Eye Lotion No. 2 would do 

 good here also, the treatment being astringent lotions, lunar caustic, or 

 cutting off the excrescent growth, according to the circumstances of the case. 



Eye, Opthalmia of the — What is called the conjunctiva is the mucous 

 membrane that lines the inner surface of the eyelids, and as its name 

 imports, joints these with the eyeball, and opthalmia is an inflammation 

 of this mucous membrane. This is a disease unfortunately common in 

 dogs; it varies greatly in severity, and in some cases, when arising from 

 constitutional causes, becomes chronic. Sporting dogs have been said to 

 be more liable to it than other breeds, but I do not think so, and I believe 

 the idea originated from the fact that these have generally been more ex- 

 posed to circumstances exciting it than other breeds. From my own exper- 

 ience, I am inclined to think it is more prevalent in pugs and other pets 

 overfed, and consequently liable to frequent derangement of the digestive 

 organs. 



Anything that will set up local irritation, as the intrusion of dust, flies, 

 etc., or the scratch of a cat, or a blow, exposure to sudden and extreme 

 changes of temperature- — as plunging into or being thrown into cold water 

 when heated — and excessive exertion is occasionally a cause, but the most 

 common sources are the vapors of foul kennels or hot stables, and de-
