4 i6 DISEASES CLASS IV. 2. 





tion of a gall-done at the other end of the bile-duct has been 

 miftaken for a pain of the ftomach. 



For the method of cure fee Clafs 1. 1.3. 8. to which mould 

 be added the uie of ftrong electric fhocks pafled through the bile- 

 duct from the pit of the ftomach to the back, and from one fide 

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

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

 where it promoted the paflage 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 infpiiikted bile. 



5. Dolor plar \ngls nb acids gafinco. The two ends of the 

 throat fympathize by fcniitive aflbciation 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 efcnpes 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 difagreeablc fenfation of heat. 



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

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

 fitive afibciations 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 ailbciation feems to take place between the agreea- 

 ble fenfations produced by food in the ftomach and bowels, arid 

 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 j 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. r. 5- 9. IV. i. 2. 9. 



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

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

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



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

 branes of 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 fliouid be covered with oiled (ilk,
