n. Fungus Heematodes, or Bleeding Cancer. 



This is a cancerous growth that may develop on any part of the body 

 but is especially apt to come in the eye, destroying that organ, and form- 

 ijig a large, spongy, fungus-like excres-- 

 ence that bleeds upon the slightest in- ^ 

 jury, in fact almost upon a mere touch. 



What to do. — When the exact nature 

 of the disease is recognized, the eye 

 should be dissected out, and the animal 

 fitted for the butcher as speedily as pos- 

 sible. The operation is the same as 

 that described under " Extirpation of fungus h^matodes. 



the Eye" in the Horse department. 



m. Torn Eyelids. 

 As in everything of the nature of a " blemish," an injury to the eye is 

 of less consequence in cattle than in the horse. Still, both humanity and 

 self-interest dictate that it should not be neglected. In a case of torn 

 eyelids, — an accident that may happen in various ways, — bring the edges 

 neatly together, and sev/ them with fine silk. Dress them afterwards 

 'with a weak carbolic or other healing lotion, applying the same two or 

 three times a day as long as necessary. 



rv. Inversion and Eversion of the Eyelids. 

 These are more of an annoj'ance than a serious ailment, and are not of 

 very frequent occurrence in cattle. Their technical names are entropium 

 and ectropium, respectively, under which they have been described in the 

 Horse department, on page 524, to w^hich the reader is referred. They 

 are identical wita what oculists are often called on to treat in the human 

 subject. 



V. Foreign Substances in the Eye. 

 Hayseed, hair, or other foreign particles in the eye always occasion 

 great annoyance, and often real suffering, which the animal will manifest 

 by keeping the eye partly closed, and perhaps by turning the head slightly 

 awry. Anything of this kind should be removed at once, the head being 

 well secured, so that the operator will run no risk of injury from the 

 horns. The method of procedure, as also the subsequent treatment, will 

 be similar to that described on page 520 for the horse. 



Pink eye in cattle: — This disease resembles epizootic catarrh in 

 that the eyes become red and tears stream down the cheeks. Those af- 

 fected usually become blind by a film growing over the ball. If an abscess 

 form, mix powdered calomel and starch in equal parts and blow into the 

 eye. Otherwise, dissolve 20 gr. of boracic acid in an oz. of water and 

 apply to the eye once or twice per day. Isolate the animal affected and 

 put in a dark stable in the dav time.
