pore. In the interior are elongated cells, with large clear nuclei, which 

 are called taste-cells. Delicate hair-like processes are connected with 

 the taste-cells and extend through the taste-pores, in the form of fine 

 filaments. Bodies similar to the taste-buds have been found on the 

 papillae of the soft palate and uvula, the mucous membrane of the epi- 

 glottis and some parts of the top of the larynx. As regards these struc- 

 tures in the tongue, it has been found that four or five months after

on the corresponding side of the posterior portion of the tongue disap- 

 pear, while they remain perfect on the sound side. 



According to the views of those who have described the so-called 

 taste-buds, sapid solutions find their way into the interior of these struc- 

 tures through the taste-pores and come in contact with the taste-cells, 

 these cells being directly connected with the terminal filaments of the 

 gustatory nerves. 



Ferrier and others have described a taste-centre near the so-called 

 olfactory centre in the uncinate gyrus ; but their observations are not 

 very definite, and the location of a centre for gustation must still be 

 regarded as uncertain.
