remaining in the alveolar proceifes ; nor was there any reafon to 

 fufpeft any difeafe of the maxillary finus. Whence this did not 

 appear to be any kind of fympathetic hemicrania. lie was af- 

 flicted with it for many years till his death. 



The cafe of Mr. B. a gentleman between 20 and 30 years of 

 age, whom I was lately concerned for, in this difeafe, is well 

 worthy a minute defcription ; I fhall therefore copy a letter, which 

 I wrote on his cafe to Mr. Cruikihank, and an anfwer I receiv- 

 ed tome time after from his partner, Mr. Leigh Thomas, who I 

 hope will publifh the fuccefsful method of cure, with adapted 

 prints. 



To Mr. Crulk/Jjanh. 



Sir, Derby, Dec. 1798. 



Mr. Bofworth, whofe cafe I wifh to remind you of, confulted 

 you fome time ago in London, and I believe that you then told 

 him, that his head-ach was owing to a difeafe of the third branch 

 of the fifth pair of nerves. He came under my care at Derby a 

 few weeks ago, and complained of much pain about the left 

 cheek-bone ; I fufpetted the antrum maxiliare might be difeafed, 

 and as the fecond of the dentes molares had then been lately ex- 

 tracted, I defired a perforation might be made into the antrum, 

 which was done by Mr. Hadley, of this town, and kept open 

 for two or three days without advantage. Afterwards, by fric-

 copioufly falivated for a few days, and had another tooth extract-

 Hadiev, fo as to divide the artery near the centre of the ear next 

 the check, hoping to divide a branch of the affected nerve, but 

 without fuccefs ; and internally, opiates in large quantity were 

 given, when the pain was exceedingly violent, the bark alfo was 

 ufed for a time in large quantity without effect. 



On attending, as much as I could, to his fenfations when in 

 pain, he feems to exprefs the commencement of the periods of 

 pain to exift about the part of the left cheek before the middle 

 of the ear \ and then draws his finger from thence to the fore 

 part of the lower jaw fometimes, and to the ala of the nofe on 

 that fide •, and at other times he draws his finger from the fame 

 part of the cheek before the ear upwards to the orbit of the eye, 

 and from thence downwards, a little way on the nofe ; and alfo 

 he complains of pain under his tongue on the fame fide. The 

 pain returns many times in an hour on fome days, and continues 

 many minutes, during which he feems to ftretch and exert his 

 arms, and appears to have a tendency to epileptic actions ; and
