Summary

1911 Encyclopædia Britannica, Volume 11… (1911)

Gegenbaur showed that “in the lowest (gristly) fishes, where hints of the original vertebrae might be most expected, the skull is an unsegmented gristly brain-box, and that in higher forms the vertebral nature of the skull cannot be maintained, since many of the bones, notably those along the top of the skull, arise in the skin.” Other publications by Gegenbaur include a Text-book of Human Anatomy (Leipzig, 1883, new ed. 1903) , the Epiglottis (1892) and Comparative Anatomy of the Vertebrates in relation to the Invertebrates (Leipzig, 2 vols., 1898–1901) .
