The colour of the lymphatic gland, depending apparently on the contents of its bloodvessels, is of a pale rose pink, resembling in this re- spect the colour of the salivary glands or of the cineritious matter of the brain ; the exceptions to this observation will be found in the mesen- teric glands while the chyle is passing through them, when they assume a whitish colour ; the lymphatic glands in the neighbourhood of the liver and gall-bladder have been observed to possess a slight yellow tinge, but this is to be con- sidered a post-mortem appearance. The black colour of the bronchial glands is remarkable and not easily accounted for ; the lymph passing from the lung to them being always perfectly transparent and colourless. The lymphatic gland has a capsule of con- densed cellular tissue, which surrounds it and firmly adheres to it, appearing to send cellular prolongations into its substance; the outer sur- face of this capsule is connected to the surround- ing textures by a loose cellular tissue. The capsule appears to serve the purposes of convey- ing the bloodvessels to the interior of the gland, of isolating it from the surrounding parts, and of preventing its over-distension by the lymph conveyed to it. The bloodvessels of the lymphatic glands art; large and distinct; frequently more than one artery is traced to a gland ; the returning veins do not generally correspond either in direction or number with the arteries. The veins are much larger, but have appeared to me fewer in number than the arteries. Nerves of considerable size pass to the lym- phatic glands and can generally be traced through them, from which circumstance it has been doubted whether any filaments are left in the °land; but if acute sensibility to pain from undue pressure or from disease be admitted as dependent upon a p
