ECT. XXXV. 2. DISEASES OF ASSOCIATION. 



Mrs. , about 30 years of age, was feized 



with great pain about the middle of the right pa- 

 rietal bone, which had continued a whole day be- 

 fore I faw her, and was fo violent as to threaten, 

 to occafion convulfions. Not being able to detect 

 a decaying tooth, or a tender one, by examination 

 with my eye, or by ftriking them with a tea-fpoon, 

 and fearing bad confequences from her tendency to 

 convulfion, I advifed her to extract the laft tooth of 

 the under-jaw on the affected iide ; which was done 

 without any good effect. She was then directed to 

 lofe blood, and to take a brifk cathartic ; and after 

 that had operated, about 60 drops of laudanum 

 were given her, with large dofes of bark ; by which 

 the pain was removed. In about a fortnight flie 

 took a cathartic medicine by ill advice, and the 

 pain returned with greater violence in the fame place, 

 and, before I could arrive, as (he lived 30 miles from, 

 me, (he fuffered a paralytic firoke; which affected 

 her limbs and her face on one iide, and relieved 

 the pain of her head. 



About a year afterwards I was again called to 

 her on account of a pain as violent as before, ex- 

 actly on the fame part of the other parietal bone. 

 On examining her mouth I found the fecond molaris 

 of the under-jaw on the fide before affected was 

 now decayed, and concluded, that this tooth had 

 occafioned the ftroke of the palfy by the pain and 

 confequent exertion it had caufed. On this account 

 I earneftly entreated her to allow the found molaris 

 of the fame jaw oppofite to the decayed one to be 

 extracted ; which was forthwith done, and the pain 

 of her head immediately ceafed, to the aiionilhment 

 of her attendants. 



In the cafes above related of the pain exifting in 

 a part diflant from the feat of the difeafe, the pain 

 is owing to defeft of the ufual motions of the pain- 

 ful part. This appears from the coldnefs, palenefs,
