A witty friend of mine expressed her sense of the remoteness of the ancient Egyptians, and her difficulty in sympathizing with them, by declaring that “_they talked in beetles, you know_.” She referred, of course, to the hieroglyphics in which that curious people now speak to us from ancient tombs. Whether those swarthy sages were eloquent and wise, or obscure and otherwise, in their beetle-speech, it is certain that entomologists of our day recognize their beetles as belonging to the same species that are now gathered into collections. Such as the Egyptians knew them, such we know them now. Nay, the sacred cats found in those ancient tombs, are cats of the same kind as our own familiar mousers; they purred before Pharaoh as they purr on our hearthrugs; and the descendants of the very dogs which irreligiously worried those cats, are to this day worrying the descendants of those sacred cats. The grains of wheat, which the _savans_ found in the tombs, were planted in the soil of France, and grew into waving corn in no respect distinguishable from the corn grown from the grain of the previous year. Have these familiar facts any important significance? Are we entitled to draw any conclusion from the testimony of paintings and sculptures, at least four thousand years old, which show that several of our well-known Species of animals, and several of the well-marked Races of men, existed then, and have not changed since then? Nimrod hunted with dogs and horses, which would be claimed as ancestors by the dogs and horses at Melton Mowbray. The Negroes who attended Semiramis and Rhamses are in every respect similar to the Negroes now toiling amid the sugar-canes of Alabama. If, during four thousand years Species and Races have not changed, why should we suppose that they ever will change? Why should we not take our stand on that testimony, and assert that Species are unchangeable? Such has been the argument of Cuvier and his followers; an argument on which they have laid great stress, and which they have further strengthened by a challenge to adversaries to produce one single case where a _transmutation_ of species has taken place:—“Here we show you evidence that Species have persisted unaltered during four thousand years, and you cannot show us a single case of Species having changed—you cannot show us one case of a wolf becoming a dog, an ass becoming a horse, a hare becoming a rabbit. Yet you must admit that if there were any inherent tendency to change, four thousand years is a long enough period for that tendency to display itself in; and we ought to see a very marked difference between the Species which lived under Semiramis, and those which are living under Victoria. Instead of this, we see that there has been no change: the dog has remained a dog, the horse has remained a horse; every Species retains its well-marked characters.”
