Howitt mentions them among the Dieri of South Australia.[830] The word _Mura-mura_, which Gason translates with Good Spirit and which he thinks expresses a belief in a god creator,[831] is really a collective word designating the group of ancestors placed by the myth at the beginning of the tribe. They continue to exist to-day as formerly. "They are believed to live in trees, which are sacred for this reason." Certain irregularities of the ground, rocks and springs are identified with these Mura-mura,[832] which consequently resemble the Altjirangamitjina of the Arunta in a singular way. The Kurnai of Gippsland, though retaining only vestiges of totemism, also believe in the existence of ancestors called _Muk-Kurnai_, and which they think of as beings intermediate between men and animals.[833] Among the Nimbaldi, Taplin has observed a theory of conception similar to that which Strehlow attributes to the Arunta.[834] We find this belief in reincarnation held integrally by the Wotjobaluk in Victoria. "The spirits of the dead," says Mathews, "assemble in the _miyur_[835] of their respective clans; they leave these to be born again in human form when a favourable occasion presents itself."[836] Mathews even affirms that "the belief in the reincarnation or transmigration of souls is strongly enrooted in all the Australian tribes."[837] If we pass to the northern regions we find the pure doctrine of the Arunta among the Niol-Niol in the north-west; every birth is attributed to the incarnation of a pre-existing soul, which introduces itself into the body of a woman.[838] In northern Queensland myths, differing from the preceding only in form, express exactly the same ideas. Among the tribes on the Pennefather River it is believed that every man has two souls: the one, called _ngai_, resides in the heart; the other, called _choi_, remains in the placenta. Soon after birth the placenta is buried in a consecrated place. A particular genius, named Anje-a, who has charge of the phenomena of procreation, comes to get this _choi_ and keeps it until the child, being grown up, is married. When the time comes to give him a son, Anje-a takes a bit of the choi of this man, places it in the embryo he is making, and inserts it into the womb of the mother. So it is out of the soul of the father that that of the child is made. It is true that the child does not receive the paternal soul integrally at first, for the _ngai_ remains in the heart of the father as long as he lives. But when he dies the _ngai_, being liberated, also incarnates itself in the bodies of the children; if there are several children it is divided equally among them. Thus there is a perfect spiritual continuity between the generations; it is the same soul which is transmitted from a father to his children and from these to their children, and this unique soul, always remaining itself in spite of its successive divisions and subdivisions, is the one which
