As a matter of fact, the totem is already itself the embodiment of a soul. Either the soul of an ancestor or that of a protective being is regarded as incorporated in the animal. The other totems, such as plants or totem fetishes (churingas), are obviously derivative phenomena, and the same is true of those legendary beings that inhabit the churingas as spirits, or that gave them to the ancestors for the purposes of magic. Now, originally, the totem was probably always an animal. But a survey of the great mass of animistic conceptions prevalent in all parts of the world shows that in this case also it is particularly the animal that is represented as capable of becoming the receptacle of a human soul after death. Animals, of course, are not all equally suited to this purpose. Some are more apt than others to be regarded as soul animals, particularly such as are characterized by rapid movement, flight through the air, or by other features that arouse surprise or uncanny dread. Thus, even in the popular belief of to-day, it is especially the snake, the lizard, and the mouse, in addition to the birds, that are counted among the soul animals. If, now, with these facts in mind, we cast a glance over the list of totem animals, we are at once struck by the fact that the most common among them are soul animals. In Australia, we find the hawk, the crow, and the lizard; in America, the eagle, the falcon, and the snake. In respect to these ideas, the totemic age marks an important turning-point in the history of soul conceptions. Primitive man regards that which we have succinctly called the 'corporeal soul' (p. 82) as the principal, and perhaps originally as the only, soul. At death, the soul is believed to remain in the body, wherefore primitive man flees in terror from the corpse. Even at this stage, of course, we occasionally find traces of a different idea. The soul may also be regarded as active outside of the body, in the form of a demoniacal being. But as yet these ideas are generally fluctuating and undefined. There then comes a change, dependent, just as are the other cultural transformations, on the strife and warfare arising as a result of tribal migrations. This change, as we may suppose, is due to the fact that tribal struggles bring with them the impressive spectacle of sudden death. One who is killed in battle exhibits the contrast between life and death so directly that, even though the belief in the continued existence of the soul within the body still survives, it nevertheless permits the co-presence of other more advanced conceptions. Thus _two_ sets of ideas come to be developed. On the one hand, the soul is believed to depart with the blood. In place of the entire body, therefore, the blood comes to be the chief vehicle of the soul. Blood magic, which by itself constitutes an extensive chapter in the history of magic beliefs, and which is prevalent in all periods of culture, has its source in this conception. Further factors
