The more ancient of the Nebraska skulls; 3. The Neanderthal man; 4. One of the Spy skulls; 5. Skull of the Java man. (Altered from Schwalbe and Osborn.) The derivation of man from an extinct tertiary Primate seems already to be wTell authenticated. Furthermore, the fossil records give evidence of the conditions under which the development of the higher races of animals began.
