  On Some Fossil Remains of Man
  by Thomas H。 Huxley
  I HAVE endeavoured to show; in the preceding Essay; that the ANTHROPINI;
  or Man Family; form a very well defined group of the Primates; between
  which and the immediately following Family; the CATARHINI; there is; in
  the existing world; the same entire absence of any transitional form or
  connecting link; as between the CATARHINI and PLATYRHINI。
  It is a commonly received doctrine; however; that the structural
  intervals between the various existing modifications of organic beings
  may be diminished; or even obliterated; if we take into account the
  long and varied succession of animals and plants which have preceded
  those now living and which are known to us only by their fossilized
  remains。  How far this doctrine is well based; how far; on the other
  hand; as our knowledge at present stands; it is an overstatement of the
  real facts of the case; and an exaggeration of the conclusions fairly
  deducible from them; are points of grave importance; but into the
  discussion of which I do not; at present; propose to enter。  It is
  enough that such a view of the relations of extinct to living beings
  has been propounded; to lead us to inquire; with anxiety; how far the
  recent discoveries of human remains in a fossil state bear out; or
  oppose; that view。
  I shall confine myself; in discussing this question; to those
  fragmentary Human skulls from the caves of Engis in the valley of the
  Meuse; in Belgium; and of the Neanderthal near Dusseldorf; the
  geological relations of which have been examined with so much care by
  Sir Charles Lyell; upon whose high authority I shall take it for
  granted; that the Engis skull belonged to a contemporary of the Mammoth
  ('Elephas primigenius') and of the woolly Rhinoceros ('Rhinoceros
  tichorhinus'); with the bones of which it was found associated; and that
  the Neanderthal skull is of great; though uncertain; antiquity。
  Whatever be the geological age of the latter skull; I conceive it is
  quite safe (on the ordinary principles of paleontological reasoning) to
  assume that the former takes us to; at least; the further side of the
  vague biological limit; which separates the present geological epoch
  from that which immediately preceded it。  And there can be no doubt
  that the physical geography of Europe has changed wonderfully; since
  the bones of Men and Mammoths; Hyaenas and Rhinoceroses were washed
  pell…mell into the cave of Engis。
  The skull from the cave of Engis was originally discovered by Professor
  Schmerling; and was described by him; together with other human remains
  disinterred at the same time; in his valuable work; 'Recherches sur les
  ossemens fossiles decouverts dans les cavernes de la Province de
  Liege'; published in 1833 (p。 59; 'et seq。'); from which the following
  paragraphs are extracted; the precise expressions of the author being;
  as far as possible; preserved。
  〃In the first place; I must remark that these human remains; which are
  in my possession; are characterized like thousands of bones which I
  have lately been disinterring; by the extent of the decomposition which
  they have undergone; which is precisely the same as that of the extinct
  species: all; with a few exceptions; are broken; some few are rounded;
  as is frequently found to be the case in fossil remains of other
  species。  The fractures are vertical or oblique; none of them are
  eroded; their colour does not differ from that of other fossil bones;
  and varies from whitish yellow to blackish。  All are lighter than
  recent bones; with the exception of those which have a calcareous
  incrustation; and the cavities of which are filled with such matter。
  〃The cranium which I have caused to be figured; Plate I。; Figs。 1; 2; is
  that of an old person。 The sutures are beginning to be effaced: all the
  facial bones are wanting; and of the temporal bones only a fragment of
  that of the right side is preserved。
  〃The face and the base of the cranium had been detached before the skull
  was deposited in the cave; for we were unable to find those parts;
  though the whole cavern was regularly searched。 The cranium was met
  with at a depth of a metre and a half 'five feet nearly'; hidden under
  an osseous breccia; composed of the remains of small animals; and
  containing one rhinoceros tusk; with several teeth of horses and of
  ruminants。  This breccia; which has been spoken of above (p。 30); was a
  metre '3 1/4 feet about' wide; and rose to the height of a metre and a
  half above the floor of the cavern; to the walls of which it adhered
  strongly。
  〃The earth which contained this human skull exhibited no trace of
  disturbance: teeth of rhinoceros; horse; hyaena; and bear; surrounded
  it on all sides。

  glabello…occipital line); 'c' auditory foramen。
  〃The famous Blumenbach* has directed attention to the differences
  presented by the form and the dimensions of human crania of different
  races。  This important work would have assisted us greatly; if the
  face; a part essential for the determination of race; with more or less
  accuracy; had not been wanting in our fossil cranium。
  'footnote' *Decas Collectionis suae craniorum diversarum
  gentium illustrata。  Gottingae; 1790…1820。
  〃We are convinced that even if the skull had been complete; it would not
  have been possible to pronounce; with certainty; upon a single
  specimen; for individual variations are so numerous in the crania of
  one and the same race; that one cannot; without laying oneself open to
  large chances of error; draw any inference from a single fragment of a
  cranium to the general form of the head to which it belonged。
  〃Nevertheless; in order to neglect no point respecting the form of this
  fossil skull; we may observe that; from the first; the elongated and
  narrow form of the forehead attracted our attention。
  〃In fact; the slight elevation of the frontal; its narrowness; and the
  form of the orbit; approximate it more nearly to the cranium of an
  Ethiopian than to that of an European:  the elongated form and the
  produced occiput are also characters which we believe to be observable
  in our fossil cranium; but to remove all doubt upon that subject I have
  caused the contours of the cranium of an European and of an Ethiopian
  to be drawn and the foreheads represented。  Plate II。; Figs。 1 and 2;
  and; in the same plate; Figs。 3 and 4; will render the differences
  easily distinguishable; and a single glance at the figures will be more
  instructive than a long and wearisome description。
  〃At whatever conclusion we may arrive as to the origin of the man from
  whence this fossil skull proceeded; we may express an opinion without
  exposing ourselves to a fruitless controversy。  Each may adopt the
  hypothesis which seems to him most probable: for my own part; I hold it
  to be demonstrated that this cranium has belonged to a person of
  limited intellectual faculties; and we conclude thence that it belonged
  to a man of a low degree of civilization: a deduction which is borne
  out by contrasting the capacity of the frontal with that of the
  occipital region。
  〃Another cranium of a young individual was discovered in the floor of
  the cavern beside the tooth of an elephant; the skull was entire when
  found; but the moment it was lifted it fell into pieces; which I have
  not; as yet; been able to put together again。  But I have represented
  the bones of the upper jaw; Plate I。; Fig。 5。  The state of the alveoli
  and the teeth; shows that the molars had not yet pierced the gum。
  Detached milk molars and some fragments of a human skull proceed from
  this same place。  The Figure 3 represents a human superior incisor
  tooth; the size of which is truly remarkable。*
  'footnote' *In a subsequent passage; Schmerling remarks upon
  the occurrence of an incisor tooth 'of enormous size' from
  the caverns of Engihoul。  The tooth figured is somewhat
  long; but its dimensions do not appear to me to be
  otherwise remarkable。
  〃Figure 4 is a fragment of a superior maxillary bone; the molar teeth of
  which are worn down to the roots。
  〃I possess two vertebrae; a first and last dorsal。
  〃A clavicle of the left side (see Plate III。; Fig。 1); although it
  belonged to a young individual; this bone shows that he must have been
  of great stature。*
  'footnote' *The figure of this clavicle measures 5 inches
  from end to end in a straight lineso that the bone is
  rather a small than a large one。
  〃Two fragments of the radius; badly preserved; do not indicate that the
  height of the man; to whom they belonged; exceeded five feet and a
  half。
  〃As to the remains of the upper extremities; those which are in my
  possession consist merely of a fragment of an ulna and of a radius
  (Plate III。; Figs。 5 and 6)。
  〃Figure 2; Plate IV。; represents a metacarpal bone; contained in the
  breccia; of which we have spoken; it was found in the lower part above
  the cranium: add to this some metacarpal bones; found at very different
  distances; half…a…dozen metatarsals; three phalanges of the hand; and
  one of the foot。
