Fig. 3 Photograph of a sagittal section of the head of the 21 mm embryo

From which the reconstruction (fig. 2) was made, and at S.R. shows this independent rod of cartilage, which is rounded in section and connected by a fibrous band with the clivus region. In a 30 mm. embryo lent by Professor Bryce of Glasgow this rod of cartilage is no longer independent.
