transjiarent protoplasm. These cells form the outermost part of the 

 epithelium, covering the end of the papilla ; all the cells belong-ing" 

 to the same papilla are of the same size. In consequence of the 

 mutual pressure which they exert on each other they present, in 

 transverse section, six-sided outlines (Fig*. 237, 2). The nuclei of 

 adjacent cells are placed at almost exactly the same level. By the 



Fig. 237. 







I. Various paiis from the fungiform papillae ; 

 after Engelmann. 



1. Nerves of a fungiform papilla. Magnified 450 



times. 



2. Surface view of the epithelium, after five 



minutes' action of iodized serum. Magnified 

 600 times. 



3. Goblet-cell with adjacent forked cell. Magni- 



fied 450 times. 



4. Portion of the papilla, after removal of the 



' goblet- and forked cells ; only cylindrical 

 cells remaining. Magnified 400 times. 

 5. Goblet-cell, with swollen contents. Magni- 

 fied 450 times. 

 6-13. Various forms of isolated forked cells. 



Magnified 450 times. 

 II. Sections of two glands of the tongue ; 

 after Biederman. 



1. Resting-gland. 



2. Gland after stimulation. 



action of reagents on these cells very remarkable forms are obtained, 

 in consequence of the protoplasm swelling and being forced up- 

 wards (Fig. 237, 5). 



(2) The cylindrical cells (Fig. 237 I) have rounded free extre- 

 mities, which reach to the general surface of the epithelium ; the 

 remainder of the cell is cylindrical except towards its lower ex-
