than men, is attended with cold extremities without fever, and 

 is diftinguifhed from the ftone of the bladder by the regularity 

 of its periods, and by the pain being not increafed after making 

 water. 



On introducing the cathether fometimes part of the urine will 

 come away and not the whole, which is difficult to explain ; 

 but may arife from the weaknefs of the mufcular fibres of the 

 bladder ; which are not liable fuddenly to contract themfelves 

 fo far as to exclude the whole of the urine. In fome old peo- 

 ple, who have experienced a long retention of urine, the blad- 

 der never regains the power of completely emptying itfelf ; and 

 many who are beginning to be weak from age can make water 

 a fecond time, a few minutes after they fuppofed they had emp- 

 tied the bladder. 



I have believed this pain to originate from fympathy with 

 fome diftant part, as from afcarides in the rectum, or from piles 

 in women ; or from caruncles in the urethra about the caput 

 gallinaginis in men ; and that the pain has been in the glans or 

 clitoris by reverfe fympathy of thefe more lenfible parts with 

 thofe above mentioned.

4. Dolor termini inteftinalis duclus choledochi. Pain at the in- 

 teftinal end of the gall-duct. When a gall-ftone 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 termin- 

 ates in the duodenum. For the actions of the two terminations 

 of this canal are affociated together from the fame ftreams 

 of bile patting through them in fucceflion, exactly as the two 

 terminations of the urethra have their actions aflbciated, as 

 defcribed in Species 2 and 3 "of this genus. But as the in- 

 teftinal termination of the bile-duct is made more fenfible for 

 the purpofe of bringing down more bile, when it is ftimulated 

 by new fupplies of food from the ftomach, it falls into violent 

 pain from afibciation ; and then the pain on the region of the 

 gall-bladder ceafes, exactly as above explained in the account 

 of the pain of the glans penis from a ftone in the fphinclcr of 

 the bladder. 



The common bile-duct opens into the interline exactly at 

 what is called the pit of the ftomach ; and hence it has fottle- 

 fimes happened, that this p-iin from aflbciation with the fcnfa-
