 To this Grantian tradition was also added a strong input of German philosophy of nature which entered British discussions in the 1820s, expounded particularly in the Hunterian Lectures in Comparative Anatomy at the Royal College of Surgeons, delivered by the British surgeon Joseph Henry Green (1791–1863). Green imported into his lectures several dimensions of Schelling’s Naturphilosophie which he used to develop a dynamic theory of species relation which synthesized the work of Lamarck, Cuvier, and the University of Göttingen medical theorist Johann Blumenbach (1752–1840 (Sloan 2007). These themes would be continued in the major series of lectures delivered by Green’s protégé at the College of Surgeons, the comparative anatomist, Richard Owen (1804–92), holder of the prestigious Hunterian Chair in Comparative Anatomy from 1837 to 1856 (Rupke 1994, 1993; Sloan (ed.) 1992). Owen’s widely-attended lectures between 1837 and 1856 brought many of the issues of anatomy, biology, and embryology to bear on the questions of species relationship and change.
