Now in every physical characteristic of the Northern, did the Mexican differ; they bore no analogy as being of the same race, either in feature, courage, endurance, or general religion. In Mexican America, Cortez, with only 500 Spanish soldiers, and those worn and dispirited, drove 50,000 Mexicans from the field of Otumba,--they fled like snow-flakes before the wind, when their standard was seized by a Spaniard; but, in the North, the fight was man to man, and no retreat--death or victory--Jerusalem or the grave! Every chieftain of the North, even upon a supposition of flight from a superior foe (either in number or prowess), may be imagined to have uttered the last words of Judas Maccabæus, when in his final battle he was opposed by twenty times his own force: "God forbid that I should do this thing, and flee from them; if our time be come, let us die manfully for our brethren, and not stain our honour!" Some of the Mexican nations worshipped idols, and knew not God!--for they sacrificed human beings to propitiate their savage Deities; not so the noble Northerns, they worship THE ONE GOD, who declared to the first Lawgiver, "Thou shalt have no other Gods before me," and their only human sacrifice is the invader of their lands and birthright. The only two analogies that existed between the North and Mexican America, and which might apparently destroy or prevent the proof of this theory, are, first, Circumcision; and second, the similitude of Language. In the North, circumcision, as we have shewn, is a religious custom only; in the Mexican territories, it was both _optional_ and religious. This strange and apparent stumbling-block in the way of proving that they are of a different race, will be removed as we proceed; for so far from injuring the proofs of the theory, it absolutely supports them, as does also the analogy in language. These important points--viz., Circumcision and Language, will be met in their respective places, and in an original manner of application; for they form two of the most substantial evidences, and were the primitive causes for our belief in the subject contemplated by this work, and especially in reference to that portion having Christianity for its basis.
