He described, it is true, the development of the external meatus of the ear and the Eustachian tube from the slit which appears between the first and the second arch, as Huschke had done before him; he described, in confirmation of Meckel, the "Meckelian process" of the hammer running down inside the lower jaw; but the discovery of the true homologies of the ear-ossicles was not made until
The lingual face of the dentary preserves an anterior dentary symphysis which originates ventrally of the first alveolus; is narrow along its length; follows the anterior margin of the dentary, curving onto the antero-ventral margin and terminating just antero-ventrally of the Meckelian foramen.
The Meckelian groove is long, straight, open and dorsal-ventrally narrow, extending posteriorly to a position ventral of tooth loci 14, where it meets a large singular foramen for the inferior alveolar nerve.
