158 DISEASES OF THE HOG. 
the rapid movement of the haw over the eye 
prevents one from’ getting hold of the offending 
body. Two drops of a three per cent solution of 
cocaine dropped into the eye will relieve the irrita- 
tion and the motion of the haw. For all forms of 
simple ophthalmia the eye should be bathed with 
cold water for ten or fifteen minutes three times a

little once a day with a clean feather; this will 
stimulate absorption and the scum will soon dis- 
appear. The pig should be kept in a moderately 
dark place until well. If the inflammation should 
be very severe, give from one to two ounces of ep- 
som salts at a dose; this will cool the system and 
act as a revulsent. 
AMAUROSIS. (PARALYSIS OF THE RETINA.) 
Amaurosis is a permanent dilatation of the pupil 
of the eye. The eye appears glassy, and in looking 
into the posterior chamber it has a greenish ap- 
pearance and is completely impervious to light. 
Causes: It is usually caused by affection of the 
optic nerve from some lesion of the brain. It is also 
caused by derangement of the digestive organs. I
