According to Sappey, Luschka, and others, they usually reach to within two or three feet of the end of the ileum. Noduli Lymphatici Solitarii.âThe solitary lymph nodules are minute masses of lymph tissue, opaque and of a whitish colour, found Aggregated lymph projecting on the surface of the mucous membrane two solitary glands throughout the whole length of both the small and large intestines. Isolated lymph cells are found in abundance scattered through the connective-tissue layer of the intestinal mucous membrane generally; in places these cells are gathered together to form little nodules, supported by a framework of retiform tissue, and sur- rounded by a lymph space which communicates below with the lymph vessels of the tela submucosa. Such a collection of lymph cells constitutes a solitary nodule. They are usually of a rounded or oval shape (Fig. 931), the wide end resting in the tela submucosa, the nodule itself piercing the lamina muscularis mucosae, and the narrow end projecting slightly above the general sur- face of the mucous membrane. In size they vary from TVth to £th of an inch (-6 to 3-0 mm.), but their average bulk is about that of a small grain of sago, to which they bear some resemblance. As already mentioned, they are present throughout the small and large intestines, being particularly abundant in the vermiform process and caecum. In the small intestine they are found on the plicae cir- culares, as Well aS Upon the general Surface Of the Solitary gland Intermediate form mucous membrane between them. Noduli Lymphatici Aggregati.âThese lymph nodules ( Peyer's patches) consist of a large number of minute lymph nodules groupe
