guc. — The tongue is preemi- 

 principal part is made up of 

 muscular fibers which run in 

 various directions, although 

 they run in similar directions 

 upon the opposite halves of 

 this organ. The tongue is 

 covered with a thick mucous 

 membrane, which contains a 

 large number of papillae simi- 

 lar to those of the skin, which 

 are of three kinds, the Filiform, 

 Fungiform, and Circumvallate. 

 The filiform are from one 

 thirty -sixth to one eighth of 

 an inch long, of a conical 

 shape, and are most abundant 

 on the middle portion of the 

 tongue. The fungiform are 

 situated upon the tip and sides 

 of the tongue, and are some- 

 what smaller than the filiform. 

 The circumvallate are from 

 six to twelve in number, and 

 are arranged upon the base 

 of the tongue in the form of 

 the letter V 3 the apex pointing 

 downwards. They consist of 

 a central round papilla fiat-
