pain has been in the glans or clitoris by reverse sympathy of these more
sensible parts with those above mentioned.

4. _Dolor termini intestinalis ductus choledochi._ Pain at the intestinal
end of the gall-duct. When a gall-stone is protruded from the gall-bladder
a little way into the end of the gall-duct, the pain is felt at the other
end of the gall-duct, which terminates in the duodenum. For the actions of
the two terminations of this canal are associated together from the same
streams of bile passing through them in succession, exactly as the two
terminations of the urethra have their actions associated, as described in
Species 2 and 3 of this genus. But as the intestinal termination of the
bile-duct is made more sensible for the purpose of bringing down more bile,
when it is stimulated by new supplies of food from the stomach, it falls
into violent pain from association; and then the pain on the region of the
gall-bladder ceases, exactly as above explained in the account of the pain
of the glans penis from a stone in the sphincter of the bladder.

The common bile-duct opens into the intestine exactly at what is called the
pit of the stomach; and hence it has sometimes happened, that this pain
from association with the sensation 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 I. 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
described by Dr. Hall, experienced on himself. Trans. of the College at
Philadelphia, Vol. I. p. 192.

Half a 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 menti
