Each is isolated by a circular trench, and is terminated by a flat summit, which is level with the surrounding sur- face, and bears numerous secondary papillae. They contain the peculiar gustatory bodies, to which fibres of the glosso-pharyngeal nerve are distributed. 4. The Papillce Foliatce (Fig. 23, 6), also known as Mayer's organs, are situated near the root of the tongue, one on each side, in front of the anterior pillar of the fauces. Each presents itself as a slightly pro- jecting oval pa
