    I/O In the mucus-flakes were large numbers of lymph-corpuscles some perfect and small, others swollen up ; many of them contam the small straight bacilli in great numbers ; besides these there were numerous coherent masses entirely com- posed of the small bacilli, but comma-bacilH were also everywhere to be found, though the small bacilli were in the majority. Cultivations made on linen from these mucus-flakes yielded after twenty-four hours large crops both of comma-bacilU and of the small straight bacilli.] These bacilli are of extremely small size, about half to two-thirds the thickness of the typical comma-bacilli, and about one-third their length. They are straight and appear pomted at each end; generally they are single, but occasion- ally they form a chain of two elements. In the well-preserved mucus corpuscles they lie closely packed together, appar- ently all single; in the large swollen corpuscles there are some in couples; and amongst those occurring free around and between the lymph-corpuscles and epithelial cells there are a good many in couples and in small groups. It is not at all a rare occurrence to meet with mucus-flakes from rice- water stools in which the corpuscles were found almost com- pletely disintegrated; there were nevertheless found many groups of the small bacilli, from six to twenty and more in each group. Two questions present themselves in connection with these lymph-corpuscles; (r) where do they come from? and (2) where do they get the bacilli from ? There can be no diffi- culty in answering the first. It is well known that in all those places where the highly-vascular lymphatic tissue reaches the free epithelium of a mucous membrane, e.g. the tonsils of the palate and pharynx, the lymph-follicles of the pyloric end of the stomach and the duodenal part of the in- testine, the solitary andagminated lymph-follicles of the ileum,
