The theory that American aboriginal civilization was derived from south-east Asia and indirectly from Egypt has received such wide publicity that it is no longer possible to dismiss it lvithout refutation and wait for it to die a natural death. Such was the policy followed when the extravagances of Lord Kingsborough claiming that the inhabitants of Central America were the lost ten tribes first saw the light. Le Plongeon's fantastic claims too had their hour and then passed into the limbo of lost causes. Other heads of this hydra, peopling Central America from the lost continent of Atlantis, from Babylonia, Africa, New Zealand, Easter Island, and in fact from nearly every quarter of the globe, were not lopped off but left to wither away from lack of that blood, so necessary to this type of hydra–reasoned argument and proof.
