I. Ophthalmia or Conjunctivitis. 



As a rule, cattle are subject to but few diseases of the eye, the most 

 common being simple soreness or inflammation of the conjunctiva (lining 

 of the lids), from the introduction of foreign bodies, exposure to cold 

 winds, scratching of thorns, or blows from horns of other cattle, or else 

 from kicks or some similar violence on the part of the attendants. 



How to know it. — There is swelling and congestion of the lids ; weep- 

 ing, the tears running down over the cheek ; shaking and hanging of the 

 head ; refusal of food ; suspension of rumination, etc. On examination, it 

 will be found that the eye is kept closed or nearly so, and is very red ; and 

 the small blood-vessels of the eye-ball are enlarged and injected. The in- 

 flammation may extend to the iTiternal parts of the eye, and pus may gather 

 and fall to the bottom of the anterior chamber, forming a whitish yellow 

 spot. Cataract may result from this, or, at least, opacity from the for- 

 mation of a Avhite film over the surface of the eyeball (cornea). 



What to do. — Give a mild purgative, No. 8. Bathe the eye with warm 

 milk and water, half and half, several times a day, and apply the follow- 

 ing lotion with a camel's hair brush directly to the eyeball and all other 

 parts, several times a day.

After the active inflammation is subdued, apply the following lotion in 

 addition to the other treatment, which should still be continued :

Apply directly to the eyeball, morning and night, with a camel's hair 

 brush. Continue this till all opacity is gone, that is, till the white half- 

 moon spot at the bottom of the anterior chamber is absorbed
