EYE DISEASES. 275 



symptoms subside. When the feet are badly affected the 

 sores burrow deep in between the hoof and the sensitive 

 structure of the foot, which results in a complete separation 

 of the hoof, and its being finally thrown off entirely. 



It is painful to look, as I have done on several occasions, 

 upon a whole row of cows suffering from suppuration, and 

 falling off of the hoofs. The loss to dairy men, consists 

 in the loss of milk, and loss of condition in the cows ; for 

 if the coAvs are properly attended to, not many of them need 

 die. The hoof will grow again, and be as useful as ever, 

 from the fact that cows like pigs are not kept for racing 

 purposes, and a second hoof, although not so strong as the 

 first one, will answer for the purpose of walking on soil 

 ground, and gathering their food. 



Treatment. Apply to the sores the following lotion : 

 Sulphate of zinc, two drachms ; Avater, one pint. 



Prevention. When once fairly established in a place, it 

 is almost a certainty that all cows and neat cattle will take 

 it, some developing: it sooner than others. To save time and 

 expense, " take the bull by the horns," and inoculate every 

 one of them. By producing the disease in this way, a 

 week or so avIU see the last of it, and by good care not 

 much time or loss will have been incurred. The milk of 

 cows affected with this disease is poison. Calves, by 

 drinking the milk of cows with this disease, will j^erish in 

 great numbers. 



Symptoms. Difficulty in swallowing, and cough ; saliva 

 driveling from the mouth. The whole accompanied by 

 fever, and frequently ending in death. 



Eyo Blseases. — Cows are not so often the subject of 

 diseases of the eye, as horses are. There is, however, one 

 disease of the eye which cows are often affected with,
