Fig. 3 Sagittal section of head end of ten-day rabbit embryo

(27A) showing oral membrane ruptured. X 50. Nasal end at right. st., stump of oral plate; other abbreviations as in figure 2.

Another ten-day embryo (27A) shows the oral membrane in the process of rupture. A sagittal section of this embryo is given in figure 3. A noteworthy feature is the presence of a thickened epithelium, continuous with the hypophysial wall, which extends nasalward from Rathke’s pocket for some distance. Its rather abrupt termination is marked by x (fig. 3).
