Scholars of the nineteenth-century race sciences have tended to identify the period from 1820-1850 as a phase of transition from philologically to physically focused study. In France, the physiologist William Frédéric Edwards (1776-1842) is normally placed near the center of this transformation. A reconsideration of Edwards' in the context of his larger biography shows that it is impossible to see a clear-cut philological to physical "paradigm shift." Although he has been remembered almost solely for his principle of the permanency of physical "types," Edwards was also committed to what he recognized as the new science of "" and proposed a new branch of comparative philology based on pronunciation. Bearing Edwards' attention to linguistics in mind, this article reconstructs his racial theories in their intellectual contexts and suggests that at a time of emergent disciplinary specialization, Edwards tried to hold discrete fields together and mold them into a new "natural history of man."
