Huxley (supported by many other anatomists) also showed conclusively that the little lobe in the interior of the brain called the "hippocampus minor" is present in the apes as in man, and that the posterior part of the greater brain, or "cerebrum," does overlap the "cerebellum" in apes and many monkeys to an even greater extent than it does in man. Owen's statements on this matter appear to have been due to his reliance on specimens of apes' brains removed from the skull and badly preserved in spirit--in which condition the parts in question had slipped out of their natural position. Owen's statements were thus fully demonstrated to be contrary to the fact, and Huxley declared, and conclusively showed, that so far from being entitled, on anatomical grounds, to a separate sub-class, man differs less from the higher apes--the four animals known as the gorilla, the chimpanzee, the orang-utan, and the gibbon--than does any one of these differ from the lower monkeys. Huxley came, therefore, to the conclusion that man could not logically be dissociated from the apes and monkeys in the way proposed by Owen, and that he should be placed with them in one "order," to which the name "Primates" (pronounced as three syllables, and having no reference to the clergy of the Anglican Church) is applied. This name was given by the great naturalist Linnæus, one hundred and fifty years ago, to the same group, in which, however, he erroneously included also the bats. It was distinctly pointed out by Huxley, and has been maintained by all those who have since occupied themselves with the matter, that there are certain very obvious differences between man and the highest ape, or that which comes nearest to him in the largest number of important features--the gorilla. The chimpanzee is practically, for the purpose of such a comparison, very nearly identical with the gorilla. Both are inhabitants of tropical Africa, whilst the next nearest, the orang and the gibbons, are inhabitants of tropical Asia. The differences separating man from these near kindred animals are differences of the size and proportion of structures present in them all, and are not due to the existence in man of actual parts or structures which are present in him and not present in these apes. Man has developed from the ape, not by the production of any new organ or part, but by the definite modification of parts already present in the apes. Even that obscure internal worm-like outgrowth of the intestine, called the "vermiform appendix," which has become so unhappily familiar to the general public of late years on account of its frequent ulceration and the consequent danger to life, is present in full size in those higher apes which I have cited by name, and is present in them and man alone amongst all the varied members of the class of mammals until we come to the little Australian beaver-like "wombat," which has a vermiform appendix or
