What is there that does not appear marvellous, when it comes to our knowledge for the first time? How many things, too, are looked upon as quite impossible, until they have been actually effected? But it is the fact, that every moment of our existence we are distrusting the power and the majesty of Nature, if the mind, instead of grasping her in her entirety, considers her only in detail. Not to speak of peacocks, the spotted skins of tigers and panthers, and the rich colors of so many animals, a trifling thing apparently to speak of, but of inestimable importance, when we give it due consideration, is the existence of so many languages among the various nations, so many modes of speech, so great a variety of expressions; that to another, a man who is of a different country, is almost the same as no man at all. And then, too, the human features and countenance, although composed of but some ten parts or a little more, are so fashioned, that among so many thousands of men, there are no two in existence who cannot be distinguished from one another, a result which no art could possibly have produced, when confined to so limited a number of combinations. In most points, however, of this nature, I shall not be content to pledge my own credit only, but shall confirm it in preference by referring to my authorities, which shall be given on all subjects of a nature to inspire doubt. My readers, however, must make no objection to following the Greeks, who have proved themselves the most careful observers, as well as of the longest standing. CHAPTER II. THE WONDERFUL FORMS OF DIFFERENT NATIONS. There are certain tribes of the Scythians, and, indeed, many other nations, which feed upon human flesh. This fact itself might, perhaps, appear incredible, did we not recollect, that in the very centre of the earth, in Italy and Sicily, nations formerly existed with these monstrous propensities, the Cyclopes, and the Læstrygones, for example; and that, very recently, on the other side of the Alps, it was the custom to offer human sacrifices, after the manner of those nations; and the difference is but small between sacrificing human beings and eating them.
