*mentioned under belladonna in inflammation of the brain, occur. Give 
‘stramonium for the symptoms indicating belladonna, if the latter remedy 
fails. Hyoscyamus is beneficial for great excitability, enlarged pupils, and 
sleeplessness. Put ten drops of the chosen remedy in a pint of water and 
give a wine-glassful once in from one to six hours, according to the severity 
of the case. Chloral hydrate or bromide of potassa will be found useful in 
“violent cases, to produce quiet, twenty to forty grains at a dose. 
LOCK-JAW.—TETANUS. 
This is a general or partial contraction of the muscles. It is more 
‘common in old horses. The causes we divide, for convenience, into two 
classes:—(1) Exposure to cold after clipping; snow and cold winds; ex- 
cessive heat; severe weather of any kind; over-exertion; worms in the 
bowels; bots in the stomach; disordered digestion; inflammation of the 
stomach, bowels, lungs, or liver; advanced stages of stomach staggers (which 
see). (2) Wounds, especially those that are not inflammatory, such as 
result from clipping; docking; nicking; castration; cutting of abscesses; 
bruises; pricks in shoeing; open joints; broken knees; nails in the sole of 
the foot; dirt; rust, or points of instruments in wounds; galling of saddle 
_or harness; severely crushed bones. Slight wounds and injuries most often 
lead to it because they are too much disregarded. Horses are rendered 
more liable to lock-jaw by low condition, cold weather, starvation, and 
other debilitating conditions. 
Symptoms.—Though these may occur within a half-hour, especially 
when the cause is found under (1) above, the effects may not come on, 
when resulting from a 
wound, until the wound 
is nearly healed. At 
first, the horse seems 
to be in good health, 
neighs when a person 
approaches, as if hun- 
gry 3 appetite usually 
good throughout; diffi- 
culty in taking food 
with the lips; champ- 
ing of jaws; grinding 
of teeth; mouth closed, 
or so nearly so that the horse can not feed; free discharge of saliva; any 
excitement causing twitching of the muscles of the neck and face; perhaps 
Move or FEEDING IN CHxonic Lock-JAw.
