weapons are as hard to distinguish by inspection as those from other parts of the world. We may reasonably suppose, moreover, that the skill of the Mexican artificer increased when he found a better material than flint to work upon. Be this as it may, an inspection of any good collection of such articles shows the much higher finish of the obsidian implements than of those of flint, agate, and rock-crystal. They say there is an ingenious artist who makes flint arrow-heads and stone axes for the benefit of English antiquarians, and earns good profits by it: I should like to give him an order for ribbed obsidian razors and spear-heads; I don’t think he would make much of them.
The wonderful similarity of character among the stone weapons found in different parts of the world has often been used by ethnologists as a means of supporting the theory that this and other arts were carried over the world by tribes migrating from one common centre of creation of the human species. The argument has not much weight, and a larger view of the subject quite supersedes it.
