The nasal cavities are relatively small; the orbits 104 ANTENATAL PATHOLOGY AND HYGIENE and their contents do not differ in their anatomy from these parts inthe child or adult. The ear of the full-time foetus has certain characters in which itresembles the ear of the adult, and others in which it differs from internal ear, for instance, is very completely dev
