SORE-THROAT. 
. This is usually one of the first indications of catarrh, 
and when confined to that portion of the throat at the 
angle of the jaws, it is termed laryngitis. The symptoms 
of this disease are well marked: the head is stiff, and if 
the throat is rubbed or pressed upon, excites coughing ;
