Show OF THE PLATES. PLATE IX. f, YIN/I , r‘ / Frc. 1. This is a sketch demonstrating that the epig‘astric artery may be cut, and shewing how it is cut. It represents the tendon of the external oblique muscle dissected, after operation. A, The direction in which the tendon was first cut, to enlarge the stric, ture, viz. upward and inward. B, The direction in which a second cut was made, the first having, as it was imagined, been insufficient. This is inward and upward ; and in this incision the epigastric artery was cut. C, The epigastric artery cut across. FIG. 2. This represents the neck of the sac of a small hernia, to demonstrate that, independent of the tendonsfthe peritoneum Will sometimes acquire a firmness and tendinous nature sufficient to strangulate. A, Marks the stringy appearance of the peritoneum, around the mouth of the sac. B, The mouth of the sac. C, A portion of the abdominal muscles, cut out with the sac. l 1 mm." PLATE X. 50W. mum Int/v This I conceive to be a curious instance of the effect of violence done to the intestine, in pushing it through the stricture, after the sac was laid open The intestine is here inverted. A, Villous and cellular coats fairly cut through. . .. "keg-42 N... - .‘. .._-.....,..- , , .. - .~_.., «Ks.._,,_;....-:.t»., B, The peritoneal coat remaining. C, An ulcerated hole in the peritoneal coat, which was a consequence of the injury. This might have been produced by the long stricture of the gut in the tendon. It might have been the effect of too much Violence in pressing the air out of the gut, before it was attempted to be pushed up : but I think I saw the finger so forcibly bored into the stricture, in attempting to push up the got, as to bmise the softer inner coats of the gut. PLATE XL This plate represents the manner in which the femoral hernia will some-a times rise from the depth of the groin, when freed of the integuments, and the binding of the fascia. A B, The extent of the incision of the integumcnts. C C, An aponeurosis dissected oi? the proper sac. I), The hernia covered by the proper eat. The tumour is of a pyramidal. form. E, A cut through the sac. \Mniva , l |
