SECT. XXX. i. PARALYSIS OF THE LIVER. 4 oj 



ated, or laftly from the abforption of the more 

 liquid parts of the bile, the remainder becomes in- 

 fpitfated, and cryiiailizes into piaffes too large to 

 J>afs, and forms another kind of jaundice, where 

 the bile-du& is not quite paralytic, or has, regained 

 its irritability. 



This difeafe is attended with much pain, which 

 at firlt is felt at the pit of the ilomach, exactly ia 

 the centre of the body, where the bile-duel: enters 

 the duodenum ; afterwards, when the fize of the 

 fcile^flones increafe, it is alfo felt on the right fide, 

 where the gall-bladder is fituated. The former pain 

 at the pit of the flomach recurs by intervals, as the 

 bile-Hone is puttied againft the neck of the duct ; 

 like the paroxyfrns of the flone in the urinary blad- 

 der, the other is a more dull and conftant pain. 



Where thefe bile-ilones are too large to pafs, and 

 the bile-dudis poffefs their fenfibility, this becomes 

 a very painful and hopelefs difeafe. I made the fol- 

 lowing experiments with a view to their chemical 

 folution. ' 



Some fragments of the Tame bile-ftone were put 

 pto the weak fpirit of marine fait, which is fold in 

 the (hops, and into folution of mild alcali; and into 

 a foluiion of cauftic alcali ; and into oil of turpen- 

 tine; without their being diflblved. All thefe mix- 

 tures were after fome time put into a heat of boil- 

 ing Water, and then the oil of turpentine diflblved 

 its fragment? of bile-ltone, but no alteration was 

 produced upon thofe in the other liquids except 

 Jo me change of their colour. 



Some fragments of the fame bile-done were put 

 into vitriolic ssther, and were quickly diffolved with- 

 out additional heat. Might not aether mixed with 

 yolk of egg or with honey be given advantageoufir 

 in bilious concretions ? 



I have in two inftances feen from 30 to 50 bile- 

 ilones come away by llool, about the iize of large 



peas
