Nevertheless, it rests upon ideas so strongly ingrained in the mind that it frequently survives its original cause for being. We have seen that in all probability, the different clans of a phratry are only subdivisions of one original clan which has been dismembered. So there was a time when all the clans, being welded together, had the same totem; consequently, wherever the souvenir of this common origin is not completely effaced, each clan continues to feel itself united to the others and to consider that their totems are not completely foreign to it. For this reason an individual may not eat freely of the totems held by the different clans of the phratry of which he is a member; he may touch them only if the forbidden plant or animal is given him by a member of the other phratry.[377]
Another survival of the same sort is the one concerning the maternal totem. There are strong reasons for believing that at first, the totem was transmitted in the uterine line. Therefore, wherever descent in the paternal line has been introduced, this probably took place only after a long period, during which the opposite principle was applied and the child had the totem of his mother along with all the restrictions attached to it. Now in certain tribes where the child inherits the paternal totem to-day, some of the interdictions which originally protected the totem of his mother still survive: he cannot eat it freely.[378] In the present state of affairs, however, there is no longer anything corresponding to this prohibition.
To this prohibition of eating is frequently added that of killing the totem, or picking it, when it is a plant.[379] However, here also there are exceptions and tolerations. These are especially in the case of necessity, when the totem is a dangerous animal,[380] for example, or when the man has nothing to eat. There are even tribes where men are forbidden to hunt the animals whose names they bear, on their own accounts, but where they may kill them for others.[381] But the way in which this act is generally accomplished clearly indicates that it is something illicit. One excuses himself as though for a fault, and bears witness to the chagrin which he suffers and the repugnance which he feels,[382] while precautions are taken that the animal may suffer as little as possible.[383]
