    numerous secreting goblet cells (Klein). Below the epithelium and separated from it by a hyaline basement membrane, is a mucosa of fibrous tissue containing numerous lymph corpuscles. The infiltration with lymph corpuscles amounts in many places to diffuse adenoid tissue, or to actual lymph follicles. In addition to a network of capillaries in its superficial layer, the mucosa contains a remarkably rich plexus of venous vessels. The deeper parts of the mucous membrane contain numerous mucous and serous glands. In parts where the mucous membrane is very thick, the glands are larger, and between them are found bundles of unstriped muscular tissue. This thickening of the respiratory mucous membrane is most marked on the inferior turbinated bone, and in this situation it forms the erectile tissue, (German Schwellgewebe originally described by Kohlrausch in 1853, afterwards by Kolliker and Henle, and which has been recently carefully examined by Voltolini. According to this author, the erectile tissue is not confined to the pos- terior extremity of the inferior concha as supposed by Kohlrausch, but extends over the whole of that bone. It is probably most noticeable after death in the posterior part, on account of the blood gravitating into that portion of the turbinated body. The frame- work of this erectile body consists* of connective tissue fibres, with many connective tissue corpuscles, and fibres of elastic tissue. The blood vessels are provided with endothelium, but are devoid of any other coats. The spaces formed by the vessels —lacunas—are few, but of large size in the anterior part, whereas at the posterior part of the concha they are * Voltolini, op. ext., p. 68. c2
