G8 DISEASES 



rangement of the digestive organs; an inverted eyelash may occasion it. 



Opthalmia is very often an accompaniment of distemper. There, is one 

 form of disease which is attended with considerable discharge from the 

 eyes undoubtedly possessing contagious qualities. This affection is known 

 as contagious optbalmia. Perhaps the most marked illustration of this va- 

 riety of the affection in the dog is that which is associated with distemper, 

 and it may be noted here that by the term opthalmia is meant the disease 

 which implicates the eyeball itself. 



The symptoms are an intolerance of light and a watery discharge, 

 and on the eyelids being opened and examined there is seen to be conges- 

 tion of the lining membrane, and across the cornea, or front clear portion 

 of the eye, there are red streaks, and ulceration soon follows, and a white 

 film abscures the eye and interferes with the sight. 



More or less opacity of the cornea is one of the symptoms of opthalmia 

 either of the simple and contagious variety, and, in the case of the dog 

 affected with the ophthalmia of distemper, the indications are of a most 

 marked character. The conjunctival membrane is highly injected and 

 reddened, the cornea becomes opaque early in the disease and very fre- 

 quently a small spot of ulceration appears in the center of it, which rapidly 

 extends, and in many cases penetrates the cornea, completely allowing 

 the fluid in the anterior chamber of the eye to escape. A .profuse dis- 

 charge of a purulent character continues during the whole course of the 

 disease, and one of the annoying features of the complaint is the glueing 

 together of the eyelids, which can only be separated by very careful and 

 continued fomentations of warm water or, what is better, warm milk. 



When treating, the cause should be first sought for, and if it is some 

 foreign irritating body, or an eyelash growing in a wrong direction, these 

 should be removed. A mild dose of cooling aperient medicine should be 

 given, and the eye should be well and frequently bathed with a decoction 

 of poppy heads; and afterward, if the inflammation is considerable, the 

 following lotion may be used several times a day with advantage: 



Eye Lotion. — Extract of belladonna, half a dram, rose water, four 

 ounces;" wine of opium, two drams — mixed. 



Eye, Cataract of the — This is an opacity of the eyeball, a whitish, 

 opaque spot, which gradually enlarges and has generally ended in blind- 

 ness. It is supposed to be incurable by our best authorities, generally 

 occurring in aged dogs — these are evidences of failing health and probable 

 breaking up of the system. It frequently follows ophtalmia, but might be 

 the result of inflammation or a wound, or blow. My Eye Lotion No. 2 

 will do some good even in such cases. 



Ear Canker, Internal. — There are two forms of this disease, internal 

 and external, the latter generally the result of the former. I will first 

 prescribe for internal. Canker is a term generally applied to different 

 obstinate, corroding, or heating humors, horses having it in the feet, 

 sheep having "foot rot;" but unless the irritation is caused in the foot 

 of the dog, sometimes by hard running on rough ground, causing canker-
