Excerpt from A Treatise on Ruptures, Containing an Anatomical Description of Each Species: With an Account of Its Symptoms, Progress, and Treatment The protruded portion of peritoneum is called the hernial sac.' This, with its contents, either passes through some natural opening in the abdominal pari etes, as at the ring or is forced through some part; where there 'is ordinarily no perforation; The cavity of the rupture is, therefore, continuous with that of the abdomen; and is lined by a prolongation of its serous membrane. The same causes, which'first produced the complaint, or others of an analogous nature, are con stantly tending to promote its increase. Hence the peritoneum, feebly opposed by the cellular membrane, and integuments, is extended so as to. Form a bag of various size and figure, communicating with the ab'do men by a comparatively small opening, called the mouth of the sac. The contracted part between the mouth, and the point, at. Which the membrane begins to expand, is the neck; and the most distant point from the abdo men, which is generally at the same time the largest, has been termed the fundus of the sac.
