They are also found to a less extent on the fungiform papillae, the papillee of the soft palate and uvula, and even on the posterior surface of the epiglottis and on the inner side of the arytenoid cartilages, and on the vocal cords. These latter localities would seem to throw doubt upon the connection between these structures and their connection with the sense of taste, but the fact that after section of the glossopharyngeal nerve these taste bulbs degenerate, and that direct communication can be traced between this nerve and these cells, would, seem to place their position as the terminal organs of the special nerve of taste beyond doubt. These taste bulbs are barrel-shaped and consist of series of nucleated external, almost cylindrical protecting cells, arranged so as to leave an opening,—the so-called gustatory pore. Lying in the axis of such a structure are found from one to ten gustatory cells, some provided with. Fig. 410.—Structure of the Gustatory Organs. (Landois.) I. Transverse section of a oircumvallate papilla: W, the papilla; v, v, the wall in section; R. R, the circular slit of fossa: K, K, the taste bulbs in position: N, N, the nerves. II. Isolated taste bulbs: D. supporting or protective cells; K, under end; E, free end, open, with the projecting apices of the taste cells. III. Isolated protective cell, d, with a taste cell, e. delicate processes at their free extremities, while their lower, fixed ends become continuous with the non-medullated terminations of the nerve of taste (Figs. 411, 412, and 413). The tongue of mammals in its general characteristics resembles that of man, and similar papillae are found on it. In the different domestic animals, especially in the herbivora, the sense of taste must differ from that in the carnivora, althoug
