(12) _The Foxhall Man_: This is the earliest known prehistoric man. He is known to us, however, only through “his flint instruments partly burned with fire, found near the little hamlet of Foxhall, near Norwich, on the east coast of England. These flints, discovered in 1921, constitute the first proofs that man of sufficient intelligence to make a variety of flint implements and to use fire existed in Britain at the close of the Age of Mammals; this is the first true Tertiary man ever found.” (Osborn: _Guide-leaflet_ to “The Hall of the Age of Man,” 2nd ed., 1923, p. 9.) Osborn assigns the twelve kinds of flint instruments typical of the Foxhallian culture to the Upper Pliocene epoch. R. A. Macalister, however, denies that the deposits are Tertiary. Abbé Henri Breuil’s verdict was undecided. In any case, the Foxhallian culture proves that the earliest of prehistoric men were intelligent like ourselves. _Summa summarum_: So far as science knows, only one human species has ever existed on the earth, and that is _Homo sapiens_. All the alleged connecting links between men and apes are found, on careful examination, to be illusory. When not wholly ambiguous in view of their inadequate preservation and fragmentary character, they are (as regards both mind and body) distinctly human, like the Neanderthal man, or they are purely simian, like the Pithecanthropus, or they are heterogeneous combinations of human and simian bones, like the Eoanthropus Dawsoni.[18] “With absolute certainty,” says Hugues Obermaier, “we can only say that man of the Quaternary period differed in no essential respect from man of the present day. In no way did he go beyond the limits of variation of the normal human body.” (“The Oldest Remains of the Human Body, etc.,” Vienna, 1905.) The so-called _Homo primigenius_, therefore, is not a distinct species of human being, but merely an ancient race that is, at most, a distinct variety or subspecies of man. In spite of tireless searching, no traces of a bestial, irrational man have been discovered. Indeed, man whom nature has left naked, defenseless, unarmed with natural weapons, and deficient in instinct, has no other resource than his reason and could never have survived without it. To imagine primitive man in a condition analogous to that of the idiot is preposterous. “For other animals,” says St. Thomas of Aquin, “nature has prepared food, garments of fur, means of defense, such as teeth, horns, and hoofs, or at least swiftness in flight. But man is so constituted that, none of these things having been prepared for him by nature, reason is given him in their stead, reason by which through his handiwork he is enabled to prepare all these things.... Moreover, in other animals there is inborn a certain natural economy respecting those things which are useful or hurtful, as the lamb by nature knows the wolf to be its enemy. Some animals also by natural instinct are aware of the medicinal properties of herbs and of other
