Changes in Adults.—The changes which take place in the in-vaginated intestine of adults are in some points identical withthose which occur in the more delicate tissues of children, but inothers they are widely different. This section^ (Fig. 12) wastaken from the ileum of a married woman, aet. 30, who was seized1 Trans. Path. Soc. Load., 1892, vol. p. 74. INTUS S US CEPTION 21 with a sudden abdominal pain on November 21. Her abdomenwas opened on November 25, and the small intestine was foundto be invaginated and irreducible for 5 inches at a point situated2 feet above the ileo-cascal valve. The intestine was cut away,and with it a small fibrous polypus undergoing calcareousdegeneration, which was attached to the mucous and muscularcoats of the ileum just above the beginning of the intussuscep-tion. The patient died of peritonitis on the day after the opera-tion. The histological changes in the intussuscepted intestine^.

Thevilli (Fig. 13) are mere shrivelled tags of connective tissue, fromwhich the columnar epithelium has disappeared, whilst theadenoid tissue, the involuntary muscle, and the central lymphatichave been replaced by small round cells, the products of thechronic inflammatory change which has affected the walls of theintestine. Congested vessels are visible here and there, and inmany places blood is extravasated into the connective submucous layer (Fig. 12), too, is full of extravasated blood,1 St. Barth. Hosp.
