308 The Discases of Animals 
The diseased parts should be wet frequently, or 
covered with a cloth wet with the following mixture : 
Tincture of chlorid of iron, one ounee; aleohol, 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, oue 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 earbolic acid. 
Erysipelas ean be transmitted to other animals 
aud 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 eoloring-imatter, commonly called 
"soot-balls,” attached to the edge (most frequently the 
upper edge) of the pupil. At the inuer corner of the 
eye, in horses and cattle, there is a thin fleshy mem- 
brane commonly called the “haw,” that can be swept. 
neross the eye to remove foreign bodies. This mem- 
brane is best developed in those animals that eannot 
rub the eves.
