ANATOMY OF THE GUSTATORY ORGAN 125 by Baginsky (1894), it has been confirmed by such a number of observers, including Drasch (1887), Ranvier (1888), Sandmeyer (1895), Meyer (1897) and others, that it is now generally accepted. Both the right and the left branches of this nerve innervate the median vallate papilla in mammals and form at the base of this organ, as Vastarini-Cresi (1915) has shown, more or less of a gusta- tory chiasma. The anterior two- thirds of the tongue in man are innervated by the lingual nerve which is made up of a union of the lingual branch of the trigem- inal nerve with the chorda tympani of the facial. It has been an open question whether the gustatory fibers for this part of the tongue belong to the trigeminal, to the facial, or possibly even to the glosso- pharyngeal, for all these nerves intercommunicate through a plexus of fine branches near their roots. F. Krause (1895) noted the effect on taste of the complete extirpation of the ganglion of the trigeminal nerve, and found that in some instances taste was entirely obliterated from the appro- priate part of the tongue, but that in others it was only somewhat reduced. These differences do not appear in the later and more conclusive work of Gushing (1903) who found that, when time enough was given, all subjects from whom the ganglion of the trigeminal nerve had been removed, recovered taste completely.
