The wreck on our shores of some solitary vessel, a circumstance dwelt upon by all who have attempted to get over the difficulties in accounting for the origin of the American people, is equally unsatisfactory; for it is but a bare supposition at best. We might as reasonably suppose any other means of peopling this continent. It is even less probable that a female was upon such a wreck, and survived the catastrophe, to constitute an American Eve. Yet supposing even this to have been the case, how long a time would have been required, from the earliest history of Carthaginian or Roman prow navigation, for the luckless navigators of their craft, with each a surviving partner, a circumstance still less probable, to have explored Central America, built numerous cities--one containing at least two millions of people--reared the most stupendous and durable edifices, and other monuments, and then to have become extinct, or identified with other species of men, and all their monuments of 'eternal rock' to have crumbled into one general wreck of matter? Could all this have happened, we ask, even supposing, for the love of conjecture, that all the rest actually did happen? We leave reasonable men to answer for themselves. But there is another reason why the Tultiques are derived from no such reputed stock, and one which every scientific man will deem conclusive, if his prejudices preclude all other sources of evidence. There are physical peculiarities, we all know, by which species of men, as well as all lower animals, are contradistinguished. These in the Tultique have so little resemblance in common with other species of mankind, ancient or modern, that no effort of the physiologist can give him, according to distinctive criteria, a homologous arrangement. He is completely alone in this respect, and consequently could not have been indebted to the people in question, from whom he most of all differed, for his origin.
