If these tentative suggestions are justified, this small fi*agmentaffords further corroboration of the opinion that I expressed to the endocranial cast of the Piltdown skull: namely,that it presents features which are more distinctlyprimitive and ape-like than those of any other memberof the human family at present available for V a = paramedian eminence ; h = de-pressed area at the lateral borderof the eminence ; c = part of thefronto-orbital margin.] Quart.
