But the fact that the things thus attached to the totem are not of a different nature from it, and consequently have a religious character, is best proved by the fact that on certain occasions they fulfil the same functions. They are accessory or secondary totems, or, according to an expression now consecrated by usage, they are sub-totems.[469] It is constantly happening in the clans that under the influence of various sympathies, particular affinities are forming, smaller groups and more limited associations arise, which tend to lead a relatively autonomous life and to form a new subdivision like a sub-clan within the larger one. In order to distinguish and individualize itself, this sub-clan needs a special totem or, consequently, a sub-totem.[470] Now the totems of these secondary groups are chosen from among the things classified under the principal totem. So they are always almost totems and the slightest circumstance is enough to make them actually so. There is a latent totemic nature in them, which shows itself as soon as conditions permit it or demand it. It thus happens that a single individual has two totems, a principal totem common to the whole clan and a sub-totem which is special to the sub-clan of which he is a member. This is something analogous to the _nomen_ and _cognomen_ of the Romans.[471] Sometimes we see a sub-clan emancipate itself completely and become an autonomous group and an independent clan; then, the sub-totem, on its side, becomes a regular totem. One tribe where this process of segmentation has been pushed to the limit, so to speak, is the Arunta. The information contained in the first book of Spencer and Gillen showed that there were some sixty totems among the Arunta;[472] but the recent researches of Strehlow have shown the number to be much larger. He counted no less than 442.[473] Spencer and Gillen did not exaggerate at all when they said, "In fact, there is scarcely an object, animate or inanimate, to be found in the country occupied by the natives which does not give its name to some totemic group."[474] Now this multitude of totems, whose number is prodigious when compared to the population, is due to the fact that under special circumstances, the original clans have divided and sub-divided infinitely; consequently nearly all the sub-totems have passed to the stage of totems.
