    in the adventitia the arrangement is that of elongated or rhombic spaces, connected by short canals, and these lacunte are lined with corpuscles resembling an endothelium, being unbranched. In any case, the corpuscles, be they branched or unbranched, are continuous with the endothelium lining the lymphatic vessel in their vicinity. In young subjects particularly, the corpuscles lining the bundles may be occasionally observed to contain two nuclei. Besides these fixed corpuscles, whose nuclei appear spindle-shaped when seen on edge, there may be seen in the mucosa occasional large granular unbranched cells, containing a relatively large nucleus which contains in its interior granules which stain deeply with nuclear staining reagents—the plasma cells of Waldeyer. The origin, functions, and behaviour in disease of these cells are as yet unknown. In connection with the bronchial lymphatics are numerous lympltadenohl JkhIIcs. They are most usually observed in the medium sized bronchi, and are situated in the walls of lymphatic vessels, both in the mucosa and adventitia. They are frequently found near the ducts of mucous glands, which they may even envelop. They consist of a delicate fibrillated reticulum, supporting capillaries, and more or less crowded with lymph corpuscles. My observations of these bodies in man would lead me to conclude that they are less cellular than the corresponding structures in the cat and guinea-pig, whilst on the other hand, they are more cellular containing less reticulum, than those in the rabbit. Burdon Sanderson observes that in the adventitia they usually occupya position near the artery. In morbid processes they are often useful as indicators of lymphatic vessels. The nerves of the bronchi have not been satisfactorily traced. They are derived from the pneumogastric and the sympathetic system. I have observed large gangliated trunks containing medullated and non-medullated fibres, c
