182 DISEASES OF THE HOG 
the seat of the injury; if the animal is made to 
move, as soon as the muscles of the face become 
affected it champs its jaws, causing a froth at the 
mouth; soon the muscles of the back become con- 
tracted, drawing the head upwards with the nose 
poked out, and the ears are pricked upwards and 
inwards, the back bent downwards and the tail 
elevated; the muscles are always in a state of con- 
traction, but if the animal is disturbed in any way 
there will be an extra spasm of the muscles which 
causes great suffering to the animal. At first the 
pulse is not much affected, but as the disease ad- 
vances and the spasms become more severe it be- 
comes faster and harder; the breathing also is fast- 
er, especially when a spasm is on, sometimes the 
spasms are so severe that the animal is thrown 
down and is unable to rise; the muscles of degluti- 
tion are sometimes affected and the animal is un- 
able to swallow. 
Treatment: The disease is the result of an over- 
exhilarated state of the spinal cord and requires a 
strong dose of medicine which will overcome this 
condition. I find that bromide of potassium will 
accomplish this providing the doses are large 
enough. Give the pig one ounce bromide of potas- 
sium at the first dose and half an ounce every two 
hours until the muscles relax, give the medicine in 
gruel. Keep the animal hungry and thirsty so 
that it will suck this into its mouth. Keep the pig 
in a dark place. There are other medicines which 
have been recommended, but they are of little use.
