Two or more variables are said to be contragredient to as many others when, on replacing those of the first set by linear functions of themselves, those of the second set become replaced by linear functions of themselves respectively inverse (or reciprocal) to the former; in other words, when the new variables, of the one set, bear to the old the same relations that the old do to the new, of the other set.
