On the third point we again quote Dr. Nott: "The only argument left, then, is that of congenital varieties or peculiarities, which are said to spring up and be transmitted from parent to child, so as to form new races. Let us pause for a moment to illustrate this fanciful idea. The negroes of Africa, for example, are admitted not to be offsets from some other race which have been gradually blackened and changed in a moral and physical type by the action of climate, but it is asserted that 'once, in the flight of ages,' some genuine little negro, or rather many such, were born of Caucasian, Mongol, or other light-skinned parents, and then have turned about and changed the type of the inhabitants of a whole continent. So, in America, the countless aborigines found on this continent, which we have reason to believe were building mounds before the time of Abraham, are the offspring of a race changed by accidental or congenital varieties. Thus, too, old China, India, Australia, Oceana, etc., all owe their types, physical and mental, to congenital and accidental varieties, and are descended from Adam and Eve! Can human credulity go further, or human ingenuity invent any argument more absurd?" But even supposing these objections to the second and third suppositions set aside, there are two other propositions which, if affirmed, as I believe they may be, entirely overthrow the orthodox assertion "that Adam and Eve, six thousand years ago, were the first pair; and that all diversities now existing must find their common source in Noah--less than four thousand three hundred years from the present time." These two are as follows. 1. That man may be traced back on the earth long prior to the alleged Adamic era. 2. That there are diversities traceable as existing among the human race four thousand five hundred years ago as marked as in the present day. To illustrate the position that man may be traced back to a period long prior to the Adamic era, we refer our readers to the chronology of the late Baron Bunsen, who, while allowing about 22,000 years for man's existence on earth, fixes the following dates, after a patient examination of the Nilotic antiquities: Egyptians under a republican form.............. 10,000 B. C. Ascension of Bytis, the Theban, first Priest King. 9,085 Elective Kings in Egypt......................... 7,280 Hereditary Kings in Upper and Lower Egypt (a double empire) form......................... 5,143* * Nott and Gliddon, "Indigenous Races," page 687. The assertion of such an antiquity for Egypt is no modern hypothesis. Plato puts language into the mouth of an Egyptian first claiming in that day an antecedent 10,000 years for painting and sculpture in Egypt. This has long been regarded as fabulous because it was contrary to the Hebrew chronology.
