DISEASES OF THE HOG. 155 



it may affect any part of the body, 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 verj^ 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 iodine with 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. I lia^ e often seen it caused bv fine cinders
