DISEASES OF THE HOG. 41 



this one except inflammation, which is vei*y short 

 in its duration, while ulceration may last for near- 

 ly a year before it destroys life. 



Treatment: There are a number of remedies 

 which can be used in the treatment of this disease. 

 Subnitrate of bismuth in ten grain doses three 

 times a day is very useful; this should be given on 

 an empty stomach. Half a grain of nitrate of silver 

 and half a grain of opium is a very valuable rem- 

 edy ; it is best given in pill and should be adminis- 

 tered three times a day before feeding. Small 

 doses of sulphate of iron are useful. One grain of 

 mercury in the form of blue mass and one-sixth of 

 a grain of ipecacuanha made into a pill and one 

 given three times a day for a week is good. 



Post Mortem Appearance. — The ulcers are usu- 

 ally found in patches of various extent and the 

 mucous membrane surrounding them is swollen 

 and of a dark-red or bluish color. The ulcers are 

 of various shapes ; some of them are pitted, others 

 are filled up w^ith a grayish-brown substance. In 

 the majority of cases they are hard to the touch or 

 to cut with the knife; sometimes they are soft. A 

 number of these ulcers seem to join together, form- 

 ing a j)atch one to two inches long and half an inch 

 wide. The root or base of the ulcer usually ex- 

 tends through the stomach, forming a hard, bluish 

 tumor; and it is said that sometimes they slougli 

 out, leaving an opening through the walls of the 

 stomach, although I have not seen such a case.
