ALLOPATHIC TKEATMENT. 209 



(d) The entrance of a calculus into the common duct 

 is marked by symptoms of a milder character than those 

 produced in the cystic duct. This is accounted for by 

 the larger size of the canal. The pain however, is very 

 severe when the concretion reaches and passes through 

 the abdominal opening. If the common duct be long 

 occluded, jaundice appears ; if the obstruction continues, 

 or becomes permanent, jaundice increases, the liver en- 

 larges, the gall-bladder becomes distended, and sooner 

 or later death ensues, unless the stone passes into the 

 bowel, or forms for itself one of those fistular openings 

 I have already described, and makes its escape either 

 into the intestinal canal, or through the walls of the 

 abdominal cavity. 



TUKATMKNT. 



ALLOPATHIC. For the relief of biliary colic, opium, 

 morphia, chloroform, Indian hemp, Belladonna, and 

 ether, with copious draughts of hot water containing 

 bicarbonate of soda, have by various authors been re- 

 commended as internal remedies. The external re- 

 medies consist of fomentations of poppy heads and 

 chamomile flowers ; linseed meal poultices ; opium and 

 Belladonna poultices; hot water, vapour, or hot air 

 baths ; opium and tobacco enemata ; the sucking of 

 ice, and bags of ice to the seat of pain. For the ex- 

 pulsion of the calculus from the alimentary canal, 

 castor oil, seidlitz powders, phosphate of soda and aloes, 

 colocynth and hyoscyamus, sulphate and phosphate of 

 soda, infusion of senna with calomel and scammony ; 

 such is the formidable armamentaria of allopathy.
