ether, not unlike that which is postulated by modern science for a precisely similar purpose, namely, to explain how things can physically affect each other through a space which appears to be empty. [Sidenote: Table of the branches of Sympathetic Magic.] It may be convenient to tabulate as follows the branches of magic according to the laws of thought which underlie them:— Sympathetic Magic (_Law of Sympathy_) Homoeopathic Magic (_Law of Similarity_) Contagious Magic​[191] (_Law of Contact_) I will now illustrate these two great branches of sympathetic magic by examples, beginning with homoeopathic magic. {p55} §2. _Homeopathic or Imitative Magic_ [Sidenote: Magical images among the American Indians.] Perhaps the most familiar application of the principle that like produces like is the attempt which has been made by many peoples in many ages to injure or destroy an enemy by injuring or destroying an image of him, in the belief that, just as the image suffers, so does the man, and that when it perishes he must die. A few instances out of many may be given to prove at once the wide diffusion of the practice over the world and its remarkable persistence through the ages. For thousands of years ago it was known to the sorcerers of ancient India, Babylon, and Egypt, as well as of Greece and Rome,​[192] and at this day it is still resorted to by cunning and malignant savages in Australia, Africa, and Scotland. Thus the North American Indians, we are told, believe that by drawing the figure of a person in sand, ashes, or clay, or by considering any object as his body, and then pricking it with a sharp stick or doing it any other injury, they inflict a corresponding injury on the person represented.​[193] For example, when an Ojebway Indian desires to work evil on any one, he makes a little wooden image of his enemy and runs a needle into its head or heart, or he shoots an arrow into it, believing that wherever the needle pierces or the arrow strikes the image, his foe will the same instant be seized with a sharp pain in the corresponding part of his body; but if he intends to kill the person outright, he burns or buries the puppet, uttering certain magic words as he does so.​[194] So when a Cora Indian {p56} of Mexico wishes to kill a man, he makes a figure of him out of burnt clay, strips of cloth, and so forth, and then, muttering incantations, runs thorns through the head or stomach of the figure to make his victim suffer correspondingly. Sometimes the Cora Indian makes a more beneficent use of this sort of homoeopathic magic. When he wishes to multiply his flocks or herds, he models a figure of the animal he wants in wax or clay, or carves it from tuff, and deposits it in a cave of the mountains; for these Indians believe that the mountains are masters of all riches, including cattle and sheep. For every cow, deer, dog, or hen he wants, the Indian has to
