It appears in the Swan-rolls, exhibited by the Right Honourable Sir Joseph Banks, that the King's Swans were doubly marked, and had, what was called two nicks, or notches. The term, in process of time, not being understood, a double animal was invented, unknown to the Egyptians and Greeks, with the name of the Swan with two Necks : but this is not the only ludicrous mistake that has arisen out of the subject, since Swan-upping, or the taking up of Swans, performed annually by the swan-companies, with the Lord Mayor of London at their head, for the purpose of marking them, has been changed by an unlucky asperite, into Swan hopping, which is not to the purpose, and perfectly unintelligible.
