Note 71 — APPENDIX.

Suppose a number of boys and girls, associated as partners for a dance, to stand up in a row, severally united, and distinguished into couples by those joining hands; the sexes being regularly alternating, so that no two of the same sex should be hand in hand. Under these conditions no effort to take a boy from one end of the row, or a girl from the other end, could be effected with the consent of the couples concerned, both partners in which would thus be deprived of the power of joining in the dance. But should it be understood that only an exchange of partners was all that should be intended, and, consistently, a boy from one end and a girl from the other end of the row, taken simultaneously and allowed to form a couple, forthwith, the rest merely shifting their hands from one neighbour to another, there would no longer be the same motive for resistance and the required exchange might be cheerfully accomplished.
