798 LIVERPOOL VETERINARY MEDICAL ASSOCIATION. 
A similar case came under Mr. Storrar’s notice more than a year 
ago, and he had been recently informed by the owner that no 
change had taken place since. Mr. Storrar considered these were 
cases of congenital amaurosis. 
The Secretary alluded to a specific form of ophthalmia which 
attacked young stock, and occasionally sheep, in the summer and 
autumn months, especially after a continuance of hot, dry weather. 
He described the attack as very sudden, assuming in a herd an 
essentially epizootic character, the whole globe of the eye being 
intensely inflamed, accompanied by abundant deposits of lymph 
in the cornea and anterior chamber, and in many instances followed 
by ulceration in the centre of the cornea. Recovery under simple 
topical and constitutional treatment the rule. Rarely the globe be¬ 
comes ruptured and vision lost. He was of opinion that entozoa 
had some influence on the production of these cases, the attacks 
being most frequently accompanied or followed by the presence of 
filaria bronchialis. 
Mr. Storrar alluded to a frequent cause of traumatic ophthalmia 
in stock, a minute particle of oat-husk becoming closely attached to 
the eyeball, defying all attempts of the animal to remove it. The 
mode he adopted for giving relief is, after folding the corner of a 
silk handerchief round the index finger, to pass it round the globe 
of the eye, and the offending body is readily detached; the after¬ 
dressing being merely nitrate of silver in the caustic form. He had 
found no treatment for ophthalmia, even in its most acute form, so 
beneficial as the free application of lunar caustic. He considered 
bleeding and physic of no use. In reply to a question by Mr. 
Wilson, said he thought the action of the silver in these cases that 
of a counter-irritant. 
Mr. Harwood had seen a collyrium, consisting of lunar caustic, 
in the proportion of ten grains to one ounce of water, very beneficial 
in cases of acute ophthalmia. 
Mr. Heyes said the most successful practice he employed was 
scarifying the palpetral conjunctivae and the administration of a 
bold cathartic. 
Mr. Wilson wished to know if any one could inform him of the 
rationale of thorough-bred horses becoming blind after undergoing 
severe exertion. 
Mr. Heyes could not explain the reason, but knew such instances 
to have occurred. He did not consider there could be any objection 
to breeding from horses rendered blind by such a cause, but, of 
course, no one could doubt that it would be most inexpedient to 
breed from animals with constitutionally diseased eyes, ophthalmia 
being especially hereditary. He saw the other day, in the neigh¬ 
bourhood of Hartford, the thorough-bred stallion Peppermint. 
This horse, he believed, became blind from over-exertion, and he 
knew him to be getting good sound stock. 
Mr. Barnes said he had known Peppermint for several years. 
He was remarkable for the goodness of his progeny ; some of them 
are now seven or eight years old. So far as he knew, the horse had
