DISEASES OF THE HOG, 179 
for the cause of disease. The lungs and stomach 
had spots of congestion. All the other organs were 
healthy. I treated the other seven with a dose of 
epsom salts and a few doses of tincture of aconite, 
but only one recovered, the others died during the 
night. 
Treatment of Inflammation of the Brain: In the 
early stage give a strong dose of epsom salts, two 
ounces to the adult pig; follow this by giving three 
to five drops of tincture of aconite if it does not 
cause vomiting; if it does, it should be discon- 
tinued. Ice to the head would be of service, but it 
is impossible to apply it to the head of the pig. A 
blister of cantharides to the back of the head may 
be of use and should be tried. 
_ CHOREA. 
Chorea: This disease affects the muscles, caus- 
ing involuntary contractions in some part of the 
body. The contractions are not rigid or persistent 
like those of tetanus, nor quick or jerking like 
those of convulsions. They resemble somewhat 
the voluntary movements. 
Causes: Defective nutrition has something to 
do with this disease, as it is often less seen in ani- 
mals of a feeble condition, some excitable state of 
the nervous system or the nerves supplying a mus- 
cle or a group of muscles. I have seen this com- 
plaint affect pigs to all appearance in the best pos- 
sible condition. It is therefore difficult to ascribe 
acause. It seldom attacks very young or very old
