Erysipelas 307 



The diseased parts should be wet frequently, or 

 covered with a cloth wet with the following mixture : 

 Tincture of chlorid of iron, one ounce; alcohol, one 

 pint; or sugar of lead, one ounce, water, one pint. Also 

 give internally every three hours '- Tincture of chlorid 

 of iron, four drams ; water, one pint. Three times 

 daily, give an ounce of hyposulfite of soda, dissolved 

 in a pint of water. When pus forms, the cavity should 

 be opened and washed out twice daily with a solution 

 of corrosive sublimate (1 to 1,000 parts of water), or 

 a 5 per cent solution of carbolic acid. 



Erysipelas can be transmitted to other animals 

 and to man by direct inoculation through a wound, 

 or by infected instruments ; but it is not contagious, 

 in the proper sense of the term. 



DISEASES OF THE EYE 



The eyes of lower animals resemble those of man 

 very closely, but the form of the pupil may give them 

 a different appearance. In the horse, the pupil is oval 

 and horizontal. In the cat, it is vertical. In the eye 

 of a horse there are small, dark brown, or black, 

 rounded masses of coloring- matter, commonlj' called 

 "soot -balls," attached to the edge (most frequently the 

 upper edge) of the pupil. At the inner corner of the 

 eye, in horses and cattle, there is a thin fleshy mem- 

 brane commonly called the "haw," that can be swept 

 across the eye to remove foreign bodies. This mem- 

 brane is best developed in those animals that cannot 

 rub the eves.
