![which they line do not exist; their partial DEFICIENCY can only be acquired and not long continued. The ExcEss OF FORMATION of the mucous membrane occurs but rarely; we must here include the congenital irregular length of some of the mucous folds, also the congenital closing of the mucous canals at their usually open extremities, or at other parts by cross bands; unnatural mucous membranes are also formed in all irregular cavities and canals, which, like the normal mucous membranes, are connected with the surface of the body, or tend to represent them at certain spots, as in abscesses and fistulas; finally, the MucoUS MEMBRANES ARE COMMONLY REPRODUCED, if they have been destroyed, either of the usual kind, or somewhat changed, as by a cicatrix.' (1) The reproduction of mucous membrane does not appear to me to be doubtful, as it is not an unfrequent occurrence, for instance, in the mouth, the nose, and the vagina; in the alimentary canal it appears also to be reproduced, although generally somewhat changed; at least I have seen newly produced skin on certain spots of an intestine which has been affected by ulceration in dysentery, although without true villi, yet villous-like, and it may be said further, with little mucous glands. [In examining the body of the late M. Beclard, who had some years previously been affected with gastric disease, sup- posed to be chronic inflammation, there was found in the lesser curvature of the stomach, a cicatrized ulcer, about the size of a sixpence, with a flat surface, and traversed by a solid cellular band, on each side of which were two lacunz formed by peritoneum; the margins were neither red nor swollen, and the rest of the stomach was sound.—vy. C. Billard De la membrane muqueuse gastro intestinale. T.] § 4. Mucous membranes assume, together with the canals which they line, the most varied Form and SIZE, as they CONTRACT themselves, even to .the closing of their canal, and on the contrary are capable of great EXTENSION; sometimes they alone are expanded, and project like bladders through clefts in the surrounding parts.’ Their THICKNESS as an individual formation varies exceedingly, and is often very much dimi- nished, either locally or generally, by excessive extension and atrophy, as well as increased to a great extent by hypertrophy, and still more by disease. The coLour is frequently irregular, sometimes it is too pale in the atrophic state of the membrane; white from the effect of sulphuric acid; frequently red in the most various shades and extent, as a consequence of irritation, congestion, effusion of blood on the surface, and inflammation;? and in consequence of the latter disease, sometimes also brown, slate-coloured, and in the mortified state and melanotic de- posits, even blackish; the mucous membrane may also some- times be irregularly coloured by food, drink, and medicines containing pigment.’ Ruprrurr of the mucous membrane,](https://iiif.wellcomecollection.org/image/b33489166_0001_0114.jp2/full/800%2C/0/default.jpg)
