chanical, and specific agencies are the usual causes. 

 The commonest cause in cattle is the presence of 

 a particle of chaff, etc., which excites not only 

 ophthalmia, but opacity of the cornea, and, in 

 some cases, leads to permanent blindness. 



In the dog, ophthalmia often occurs during 

 distemper, and the eyeball may be the seat of 

 ulceration. The writer believes that there is a 

 specific or recurrent ophthalmia affecting this 

 animal, which usually produces complete dis- 

 organisation of the eye-ball, and is incurable, as a 

 rule. 



When the eye-lids are torn, ophthalmia generally 

 follows. If possible remove the cause. Mild 

 cases may be treated with a little Boracic Ointment, 

 or mild yellow Oxide of Mercury Ointment, but 

 when the cornea is cloudy, lead compounds ought 

 not to be used, as such a chemical precipitates 

 the albuminous matter of the cornea. Perhaps 

 the most economical is early Veterinary advice.
