and fatal termination as in the ox and sheep. Sometimes it 
rages like an endemic through the piggery. The remedies are, 
as in the other cases, bleeding, but here from the palate, for we 
could not manage the hog sufficiently to open the jugular. 
Epsom salts or sulphur should be given as purgatives. The 
subsequent, and also the precautionary measures, are food less 
in quantity, or of a less stimulating character.

11. Simple Wounds of the Parietes of the Chest, with the 
injection of water at different temperatures into the pectoral 
cavity. 
We have attempted this experiment on two horses. We in¬ 
jected four ounces of water at a temperature of 10® (54° Fah.) 
into the left pleural cavity. The respiration was increased during 
some instants. He pawed with his fore foot for several minutes 
afterwards, and then every function seemed to return to its na¬ 
tural state. The operation was carefully performed, and no air 
was suffered to enter the wound. 
We injected, or rather poured, into the left pectoral cavity, six 
litres (rather more than 12^11)) of water, at a temperature of 
32°-fO (90°Fah. ?), and a very small quantity of air only entered 
with the water. 
The operation was performed at p.m. Immediately after¬ 
wards the respiration became accelerated, and the flanks fell 
suddenly when every act of expiration commenced. The sound 
returned by percussion was diminished towards the inferior part 
of the left pectoral cavity. At 3| p.m. the right side had lost its 
resonance, probably because that, during the quarter of an hour 
that had elapsed since the introduction of the water, the liquid 
had found its way from one sac into the other. Ten minutes 
after the injection the horse had a strong shivering fit, and 
during this time the animal dunged twice, and pawed the ground 
with his foot. At 4J p.m. he lay down; the respiratory action 
was exceedingly quickened, and the souhresaut^ of broken wind 
was strongly marked. He ate with appetite the hay that was 
* The term souhresaut is applied by the French to that double convulsive 
muscular effort seen in the flank, which accompanies the act of expiration.
