As we stated in the Introduction to this volume, a mere glance cast upon this skull is sufficient to bring to naught all that has been written and propounded touching the organic consanguinity which is asserted to exist between man and the ape, to say nothing of the objects produced by primitive man--objects which, in this work, we are studying in all necessary detail. An examination of the labours of primitive man is the best means of proving--every other consideration being set aside--that a great abyss exists between him and the animal; this is the best argument against our pretended _simial_ origin, as it is called by those who seek to veil their absurd ideas under grand scientific phrases.

Tombs and Mode of Interment during the Polished-stone Epoch-- _Tumuli_ and other sepulchral Monuments formerly called _Celtic_--Labours of MM. Alexandre Bertrand and Bonstetten-- Funeral Customs. Having in our previous chapters described and delineated both the weapons and instruments produced by the rudimentary manufacturing skill of man during the polished-stone epoch; having also introduced to notice the types of the human race during this period; we now have to speak of their tombs, their mode of interment, and all the facts connected with their funeral customs.
