tion of a gali-ftone at the other end of the bile-duct has been 

 miftaken for a pain of the ftomach. 



For the method of cure fee Oafs I. 1.3. 8. to which ihould 

 be added the ufe of ftrong electric fhocks palTed through the bile- 

 duel; from the pit of the ftomach to the back, and from one fide 

 to the other. A cafe of the good effect of electricity in the 

 jaundice is related in Seel. XXX. 2. And another cafe, 

 where it promoted the paffage of a painful gall-ftone, is defcrib- 

 ed by Dr. Hall, experienced on himfelf. Tranf. of the Col- 

 lege at Philadelphia, Vol. I p. 192. 



Half a pint of warm water two or three times a day is much 

 recommended to dilute the infpiflated bile. 



5. Dolor pharyngis ab acido gajirico. The two ends of the 

 throat fympathize by fenfitive alTociation in the fame manner 

 as the other canals above mentioned, namely, the urethra and 

 the bile-duct ; hence when too great acidity of undigefted ali- 

 ment, or the carbonic acid air, which efcapes in fermentation, 

 ftimulates the cardia ventriculi, or lower end of the gula, into 

 pain, the pharynx, or upper end of it, is affected with greater 

 pain, or a difagreeable fenfation of heat. 



6. Pruritus narium a vermibus. The itching of the nofe from 

 worms in the inteftines is another curious inftance of the fen- 

 fitive affociations of the motions of membranes •, efpecially of 

 thofe which conftitute the canals of the body. Previous to the 

 deglutition of agreeable food, as milk in our earlieft infancy, an 

 agreeable odour affects the membrane, which lines the noftrils; 

 and hence an alTociation feems to take place between the agreea- 

 ble fenfations produced bv food in the ftomach and bowels, and 

 the agreeable fenfations of the noftrils. The exiftence of afcar- 

 ides in the rectum I believe produces this itching of the noftrils 

 more than the worms in other parts of the inteftines ; as we have 

 already feen, that the terminations of canals fympathize more 

 than their other parts, as in the urethra and gall-ducts. See 

 Clafs I. 1. 5. 9. IV. 1. 2. 9. 



7. Cephalita fympathetica. Sympathetic head-ach. In cold fits 

 of the ague, the head-ach arifes from confent with fome torpid 

 vifcus, like the pain of the loins. After drunkennefs the head- 

 ach is very common, owing to direct fympathy of the mem- 

 branes of the head with thofe of the ftomach ; which is become 

 torpid after the too violent ftimulus of the preceding intoxica- 

 tion ; and is hence removable by fpirit of wine, or opium, ex- 

 hibited in fmaller quantities. In fome conftitutions thefe head- 

 achs are induced, when the feet are expofed to much external 

 cold •, in this cafe the feet (hould be covered with oiled filk,
