LOCKED JAW. 
Iv some instances the locked-jaw comes on suddenly ; but it more 
usually attacks in a more general manner, in which ease a slight © 
stiffness is first perceived in the back part of the neck, which, after 
a short time, becomes considerably increased, and at length renders 
the motion of the head both difficult and painful. There is also a 
difficulty of swallowing, great tightness about the chest, and pain at _ 
the extremity of the breast bone, shooting into the back. A stiffness 
also takes place in the jaws, which soon increases to such a height — 
that they become so closely set together as not to admit of the small- 
est opening. et ss 
_ Sometimes this spasmodic affection extends to the muscles of the 
back, and the spine is bent either forwards or backwards. The belly 
is also strongly retracted, and feels hard, producing obstinate cos- 
tiveness. ‘The spasm continuing to increase the muscles of the head 
and trunk become so rigidly extended as to keep them immoveably 
straight. The arms also become firmly extended, and the tongue is 
affected. ‘The disorder continuing to advance, every organ of vo- 
luntary motion becomes affected, the eyes are rigid and imr as 
in their sockets, the countenance is hideously distorted, ind | 
presses great distress, the strength is exhausted, the pulse is lrregu+ 
lar, and one universal spasm puts a period to a most miserable state 
_of existence. 
These affections are occasioned either by exposures to cold, when 
under profuse perspiration, sleeping in open air, on damp ground ; 
by worms, by injuries of the nerves, from puncture, incision, or 
laceration ; by wounds of tendinous parts, particularly in bleeding © 
in the arm, which is a frequent source of these complaints. They 
ofien succeed surgical operations. : = 
Lobelia emetics, frequently repeated, may be depended upon pret- 
ty certainly, for relaxing all spasms of this nature. They may be 
assisted by warm drinks, and the fever powders. If we cannot ad- 
minister medicine without, we must extract or break out one or two 
teeth. oe 
__If it proceed from a wound or injury, it should be carefully cleansed 
of all extraneous substances, and dressed with tincture of opium, 
and soft ointment, Clysters may be administered with advantage.

SEA SICKNESS. 
Tue cause of this distressing affection is the well known motion _ 
of a vessel on the surface of the water. The most alarming, nay, even” 
fatal, consequences have been known to result from the violent retch-_ 
ing and-vomiting produced by the motion of the vessel, withou 
being in the power of any one to stop it; for if it-be true th 
_. Sickness is only to be cured by habit, what hope can be he
