GANGRENOUS INFLAMMATION. (GANGRENA ORIS.) 
This is a disease which is usually seen in the 
young, especially those having a white skin. The 
probability is that it depends upon a peculiar mor. 
bid condition of the system and only wants some 
exciting cause to bring it out. The teeth seem to 
be in some way connected with it. 
Symptoms: It is not usually noticed in the early 
-Stages. It begins most commonly by the appear- 
ance of white or ash-colored patches on the gums, 
most frequently below the lower incisor teeth, al- 
though it may occur on any part of the mouth; 
there is usually not much inflammation or swell- 
ing; in some cases where the inside of the cheek is 
the part affected, there may be so much swelling 
that it is observed from the outside, and the an- 
imal seems to suffer considerable pain, especially 
when it tries to eat; the patient often suffers from 
weakness. As the disease advances the slough 
spreads, and the external parts become hard to 
the touch; there will be a flow of saliva and the 
breath becomes fetid. I have seen a case of this: 
kind where the complaint penetrated the deep 
structures and caused necrosis of the bone (death 
of the bone); the teeth became loose and the pig 
had to be destroyed. In the majority of cases, as 
the disease advances, the animal is unable to take 
food; an exhaustive diarrhea sets in and carries 
off the animal. 
Treatment: In the early stages of the disease 
take sulphate of copper, half a dram to the ounce
