DISEASES OF THE HOG. 155 
it may affect any part of the oe but most fre- 
quently the face and ears. 
Symptoms: There appears a gray crust on the 
skin and the hair drops out; this keeps spreading 
in the form of a ring until the whole side of the 
face or ears are covered with it. The center parts 
become dry and hard, but the edges of the ring, if 
examined closely, are found to be very small vesi- 
cles, more or less moist. This disease is contagious 
to man to a certain extent; that is, it will develop 
for a time and then die. ; 
Treatment: First remove as much of the crust 
as possible by washing with soap and water, using 
a brush, then dry the surface, and mix two drams 
of iodineewith two ounces of vaseline and rub a 
little of this well in; repeat in a week if necessary; 
or mix carbolic acid one ounce, alcohol two ounces; 
apply a little with a small brush or a feather; re- 
peat in a week, if needed. 
SORE FEET. 
Pigs which are kept on hard, slippery floors suf- 
fer from inflammation of the sensitive parts of their 
feet. I have seen some very heavy hogs suffer from 
-the same cause on hard, dry ground. There are also 
cases of sores breaking out at the back of the hoof 
and between the toes. This is called “foul in the 
feet;” but I have not seen any cases of the conta- 
gious foot disease in this country, and the one to be 
described is a local disease caused by some sub- 
stance irritating the parts at the heel or between 
the toes, Ihave often seen it caused by fine cinders
