"In spite of its curious characteristics, the Neanderthal skull none the less belonged to an individual, who, to judge by other bones which have been found, diverged but little from the average type of the present Germanic races, and by no means approximated to that of the ape. "Is it probable, proceeding even on the class of ideas which I am opposing, that in a being in a state of transition between man and the anthropomorphous apes, the body would have become entirely human in its character, whilst the head presented its simial peculiarities? If a fact like this is admitted, does it not render the hypothesis absolutely worthless? "Notwithstanding all the discussion to which these curious remains have given rise, it appears to me impossible to look upon them in any other light than as the remains of an individuality, exceptional, no doubt, but clearly belonging to the human species, and, in addition to this, to the Celtic race, one of the branches of our Aryan stock. M. Pruner-Bey appears to me to have placed this fact beyond all question by the whole mass of investigations which he has published on this subject. The most convincing proofs are based on the very great similarity which may be noticed in a Celtic skull taken from a tumulus in Poitou to the skull which has become so well known and, indeed, so celebrated owing to the writings of Doctor Schaaffhausen. This similarity is not merely external. An internal cast taken from one skull fits perfectly into the interior of the other. It was, therefore, the _brains_ and not merely the _skulls_ which bore a resemblance to one another. The proof appears to me to be complete, and, with the learned author of this work, I feel no hesitation in concluding that the Neanderthal skull is one of Celtic origin. "After all, neither experience nor observation have as yet furnished us with the slightest data with regard to man at his earliest origin. Science, therefore, which pretends to solidity of character, must put this problem on one side till fresh information is obtained. We really approach nearer to the truth when we confess our ignorance than when we attempt to disguise it either to ourselves or others. "With regard to the simial origin of man, it is nothing but pure hypothesis, or rather nothing but a mere _jeu d'esprit_ which everything proves utterly baseless, and in favour of which no solid fact has as yet been appealed to." In dealing with this question in a more general point of view, we must add that the most enlightened science declares to us in unmistakable accents, that species is immutable, and that no animal species can be derived from another; they may change, but all bear witness to an independent creation. This truth, which has been developed at length by M. de Quatrefages in his numerous works, is a definitive and scientific judgment which must decide this question as far as regards any unprejudiced minds.
