DISEASES OF THE HOG. 41 
this one except inflammation, which is very 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 
au 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 with 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 patch 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 slough 
out, leaving an opening through the walls of the 
stomach, although I have not seen such.a case.
