    of the writer’s very early cases was one in which the peritoneal cavity was filled with pus. Post- mortem examination discovered pus in the appendix, but no visible lesion in the organ by which it could have passed into the cavity.] The deeper part of the serous layer is of fine connective tissue, which binds the peritoneal surface to the outer portions of the muscular layer. The muscular layer, like that of the intestines, is in two parts, the outer longitudinal, the inner circular. The outer or longitudinal layer consists of bands of muscular fibres running, as the name implies, lengthways in the organ, in discontinuous groupings not unlike the bands in the caecum. In the intervening spaces between those bands are found connective tissue, blood-vessels, and lymphatic spaces. These gaps are important in the spread of infection, as noted already in the case of the stomata in the peritoneal layer. The inner or circular muscular layer consists of thick, firm and continuous muscular rings. The sub-mucous layer is composed of fibro-elastic, connective tissue, many small blood-vessels, some fat, and lymphatics. The mucous layer is the usual mem- brane, composed of cylindrical epithelium cells arranged on a connective-tissue basement-membrane with tubu- lar glands and lymphoid follicles, which latter are the essential part of the organ. The tubular glands are situated in a network of very fine connective tissue; they are racemose in appearance, and are confined entirely to the mucous layer. They do not penetrate to the muscular layer, which the
