ORGAN OF TASTE. 251 



and, a little later, Schwalbe l described, under these names, 

 peculiar structures, which are supposed to be the true organs 

 of taste. They are found on the lateral slopes of the circum- 

 vallate papillae and occasionally on the fungiform papillae. 

 The structure of these organs is very simple. They consist 

 of flask-like collections of spindle-shaped cells, which are 

 received into little excavations in the epithelial covering of 

 the mucous membrane, the bottom resting upon the con-

 seen that the base is covered with secondary papillae ; 2, groove between the papilla and the 

 surrounding wall ; 3, 8, wall of the papilla. 



Fig. 22. Fungiform, filiform, and hemispherical papillae. 1, 1, two fungiform papillae, cov- 

 ered with secondary papillae; 2, 2, 2, filiform papillae; 3, a filiform papilla, the prolonga- 

 tions of which are turned outward ; 4, a filiform papilla, with vertical prolongations ; 5, 5, 

 small filiform papillae, with the prolongations turned inward; 6, 6, filiform papillae with 

 striations at their bases; 7, 7, hemispherical papillae, slightly apparent, situated between 

 the fungiform and the filiform papillae. (SAPPEY, Traite cPanatomie, Paris, 1871, tome iii.,

nective-tissue layer. Their form is ovoid, and, at the neck 

 of the flask, is a rounded opening, called the taste-pore. 

 Their length is from -$^ to -g-^, and their transverse diame- 

 ter, about -g-J-g- of an inch. 8 The cavity of the taste-beakers is
