276 OF HYDATIDS. 



father to" visit a man forty years of age, who had a 

 swelled liver, which was followed by ascites, jaun- 

 dice, and the discharge of hydatids by stool, and 

 who died in the course of six weeks. My father 

 expected to find a sac with hydatids attached to the 

 stomach or intestine, and communicating with them; 

 but instead of this, the outer part of the sac, con- 

 taining the hydatids, was found entire, and did not 

 adhere to the alimentary canal. On opening the 

 cyst, the concave part of the liver was found wasted 

 to a considerable depth, and at the bottom of the 

 cyst, the branches of the biliary ducts were seen 

 ■without dissection, bare, and greatly enlarged, with 

 a number of holes in their sides, through which the 

 hydatids had passed into the duodenum. The 

 great enlar^^ement of tlie biliary ducts was proba- 

 bly produced by the irritation of the hydatids, 

 and by the mechanical obstruction caused by the 

 pressure of the hydatids, on the lo>ver ends of the 

 biliary ducts, to which tlie pressure of an enlarged 

 lymphatic gland, which lay over the common duct, 

 had probably contributed. 



" Case 7. In the year 1783, my father was 



consulted by Mr. twelve years of age, who 



had a swelling in the upper and right side of his 

 belly. The swelling gradually increased very con- 

 siderably. In the under part of the swellii;g, the 

 liver was felt in a sound state. At last the fluctua- 

 tion of a liquor above the solid part of the tumour 

 became very obvious.
