- 1The hyomandibular, quadrate, symplectic, and styIohyoid are, in the 5 mm. stage, all one mass of cartilage.
- 2This mass is fused, at this stage, to the cranial cartilage and to Meckel's cartilage.
- 3The palato-pterygoid forms at about 13 mm., and grows back to meet the quadrate.
- 4Until the 20 mm. stage is reached, the brain is in no place roofed over.
- 5The Trabeculæ Cranii disappear between 20 mm. and 30 mm., leaving a median process, which does not join the posterior part of the skull.
- 6The quadrate appears by a constriction in the hyomandibular mass.
- 7The symplectic appears as a thin pointed process from beneath this mass.
- 8Articulations of this mass with the cranium and with Meckel's cartilage appear at 10 mm. and 26 mm. respectively.
- 9Considerable ossification is taking place at 30 mm.
