A woman may not name her father-in-law, nor on any account her son-in-law. Two people whose children have intermarried are also debarred from mentioning each other’s names. And not only are all these persons forbidden to utter each other’s names; they may not even pronounce ordinary words which chance to be either identical with these names or to have any syllables in common with them. “A man on one occasion spoke to me of his house as a shed, and when that was not understood, went and touched it with his hand to shew what he meant; a difficulty being still made, he looked round to be sure that no one was near and whispered, not the name of his son’s wife, but the respectful substitute for her name, _amen Mulegona_, she who was with his son, and whose name was Tuwarina, Hind-house.” Again, we hear of a native of these islands who might not use the common words for “pig” and “to die,” because these words occurred in the polysyllabic name of his son-in-law; and we are told of another unfortunate who might not pronounce the everyday words for “hand” and “hot” on account of his wife’s brother’s name, and who was even debarred from mentioning the number “one,” because the word for “one” formed part of the name of his wife’s cousin.(1303) (M208) It might be expected that similar taboos on the names of relations and on words resembling them would commonly occur among the aborigines of Australia, and that some light might be thrown on their origin and meaning by the primitive modes of thought and forms of society prevalent among these savages. Yet this expectation can scarcely be said to be fulfilled; for the evidence of the observance of such customs in Australia is scanty and hardly of a nature to explain their origin. We are told that there are instances “in which the names of natives are never allowed to be spoken, as those of a father or mother-in-law, of a son-in-law, and some cases arising from a connection with each other’s wives.”(1304) Among some Victorian tribes, a man never at any time mentioned the name of his mother-in-law, and from the time of his betrothal to his death neither she nor her sisters might ever look at or speak to him. He might not go within fifty yards of their habitation, and when he met them on a path they immediately left it, clapped their hands, and covering up their heads with their rugs, walked in a stooping posture and spoke in whispers until he had gone by. They might not talk with him, and when he and they spoke to other people in each other’s presence, they used a special form of speech which went by the name of “turn tongue.” This was not done with any intention of concealing their meaning, for “turn tongue” was understood by everybody.(1305) A writer, who enjoyed unusually favourable opportunities of learning the language and customs of the Victorian aborigines, informs us that “A stupid custom existed among them, which they called _knal-oyne_. Whenever a female child was promised in marriage to any man,
