Even the very lowest Egyptians would not touch any thing a Grecian knife had polluted--the very rigidity with which caste was preserved in Egypt would forbid the propagation of castes among barbarians so much below the very lowest caste they could introduce.

So far, therefore, from Egyptian adventurers introducing such an institution among the general population, their own spirit of caste must rapidly have died away as intermarriage with the natives, absence from their countrymen, and the active life of an uncivilized home, mixed them up with the blood, the pursuits, and the habits of their new associates.

Lastly, If these arguments (which might be easily multiplied) do not suffice, I say it is not for me more completely to destroy, but for those of a contrary opinion more completely to substantiate, an hypothesis so utterly at variance with the Athenian character--the acknowledged data of Athenian history; and which would assert the existence of institutions the most difficult to establish;--when established, the most difficult to modify, much more to efface.

[74] Homer--so nice a discriminator that he dwells upon the barbarous tongue even of the Carians--never seems to intimate any distinction between the language and race of the Pelasgi and Hellenes, yet he wrote in an age when the struggle was still unconcluded, and when traces of any marked difference must have been sufficiently obvious to detect--sufficiently interesting to notice.

[77] With all my respect for the deep learning and acute ingenuity of Mueller, it is impossible not to protest against the spirit in which much of the History of the Dorians is conceived--a spirit than which nothing can be more dangerous to sound historical inquiry.

A vague tradition, a doubtful line, suffice the daring author for proof of a foreign conquest, or evidence of a religious revolution.
