Of the mesal derivatives of the lingual sulcus our knowledge ismeager. In the 20 millimeter embryo a flange of the same form asthe sublingual is directed mesad into the substance of the tongue. In THE DEVELOPMENT OF THE SALIVARY GLANDS IN MAN 67 the 22 millimeter embryo a plug is attached to the lingual sulcus ashort distance caudad of the frenulum. In his 10 weeks embryo Chie-vitz describes a small plug arising from the lingual sulcus, but in this. Fig. 27.

Its direction is not stated, and it is men-tioned in connection with the lesser subungual glands; its identitywith the mesally directed plugs is more than cjuestionable. Of thesubsequent history of this element nothing is known. Its presence isnot recorded in Bujards careful study of his 5 centimeter these sprouts represent the apical gland is only a conje
