Although the glands of von Ebner have been believed to be purely serous glands, they may be of the mixed type in some cases. In order to ascertain the occurrence of mucous cells in the glands and to study the staining properties of them, the authors obtained 23 vallate papillae from 7 Korean adult tongues, cut them serially and stained them with the hematoxylin and eosin, mucicarmine, mucihematein, toluidin blue or ferric mannitol technic.
