416 DISEASES CLASS IV. 2. 2. 5. 



lion of a gall-stone at the other end of the bile-duct has been 

 mistaken for a pain of the stomach. 



For the method of cure see Class 1.1.3. 8. to which should be 

 added the use of strong electric shocks passed through the bile- 

 duct from the pit of the stomach to the back, and from one side 

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

 jaundice is related in Sect. XXX. 2. And another case, 

 where it promoted the passage of a painful gall-stone, is describ- 

 ed by Dr. Hall, experienced on himself. Trans, of the College 

 at Philadelphia, Vol. I. p. 192. 



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

 recommended to dilute the inspissated bile. 



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

 throat sympathize by sensitive association in the same manner 

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

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

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

 stimulates 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 disagreeable sensation of heat. 



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

 \vorms in the intestines is another curious instance of the sen- 

 sitive associations of the motions of membranes; especially of 

 those which constitute the canals of the body. Previous to the 

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

 agreeable odour affects the membrane which lines the nostrils; 

 and hence an association seems to take place between the agree- 

 able sensations produced by food in the stomach and bowels, and 

 the agreeable sensations of the nostrils. The existence of asca- 

 rides in the rectum I believe produces this itching of the nostrils 

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

 already seen, that the terminations of canals sympathize more 

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

 Class I. 1.5.9. IV. 1. 2. 9. 



7. Cephalwa sympathetica. Sympathetic head-ach. In cold fits 

 of the ague, the head-ach arises from consent with some torpid 

 viscus, like the pain of the loins. After drunkenness the head- 

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

 branes of the head with those of the stomach; which is become 

 torpid after the too violent stimulus of the preceding intoxica- 

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

 hibited in smaller quantities. In some constitutions these head- 

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

 cold; in this case the feet should be covered with oiled silk.
