A usage among diplomatists by which the rank and places of different powers, who have the same right and pretensions to procedence, are changed from time to time, either in a certain regular order, or one determined by lot In drawing up treaties and conventions, for example, it is the usage of certain powers to alternate, both in the preamble and the signatures, so that each power occupies, in the copy intended to be delivered to it, the first place.
