wounded tendon, like the wounds from the bite of a mad dog, did 

 not produce the hydrophobia, and then the locked jaw, till seve- 

 ral days after the accident. 



I twice witnessed the locked jaw from a pain beneath the 

 sternum, about the part where it is complained of in painful 

 asthma, or angina pectoris, in the same lady at some years dis- 

 tance of time. The last time it had continued two days, and she 

 wrote her mind or expressed herself by signs. On observing a 

 broken tooth, which made a small aperture into her mouth, I 

 rolled up five grains of opium like a worm about an inch long, 

 and introducing it over the broken tooth, pushed it onward by 

 means of a small crow-quill; as it dissolved I observed she swal- 

 lowed her saliva, and in less than half an hour she opened her 

 mouth and conversed as usual. 



Men are taught to be ashamed of screaming from pain in their 

 early years; hence they are prone to exert the muscles of the 

 jaws instead, which they have learnt to exert frequently and 

 violently from their infancy; whence the locked jaw. This and 

 the following spasm have no alternative relaxations, like the pre- 

 ceding ones; which 'is perhaps owing, first, to the weakness of 

 their antagonist muscles, those which elevate the jaw being very 

 strong for the purpose of biting and masticating hard substances, 

 and for supporting the under jaw, with very weak antagonist 

 muscles; and secondly, to their riot giving sufficient relief even 

 for a moment to the pain, or its preceding irritation, which ex- 

 cited them. 



M. M. Opium in very large quantities. Mercurial oinK 

 ment used extensively. Electricity, Cold bath. Dilate the 

 wound, and fill it with lint moistened with spirit of turpen- 

 tine; which inflames the wound, and cures or prevents the con- 

 vulsions. See a case, Transact, of American Society, Vol. II. 

 p. 227. 



Wine in large quantities in one case was more successful than 

 opium; it probably inflames more, which in this disease is de- 

 sirable. Between two or three ounces of bark, and from a quart 

 to three pints of wine a day, succeeded better than opium. Ib. 



14. Tetanus dolorificus. Painful cramp. This kind of spasm 

 most frequently attacks the calf of the leg, or muscles of the 

 toes; it often precedes paroxysms of gout, and appears towards 

 the end of violent diarrhoea, and from indigestion, or from acid 

 diet. In these cases it seems to sympathize with the bowels, but 

 is also frequently produced by the pain of external cold, and by 

 the too great previous extension of the muscles, whence some 

 people get the cramp in the extensor muscles of the toes after
