(1) We learn the order of the entire series of thirty-seven sovereigns by means of the relations, direct and indirect, which we establish with the reigning sovereign, Victoria. (2) The precise credit is claimed for this method which it is entitled to receive. In a list of proper names we sometimes have several surnames alike, with usually a difference of Christian names, as in the presidential series we have--_William Henry_ Harrison and _Benjamin_ Harrison, and _John_ Adams and _John Quincy_ Adams, and we also sometimes have the same Christian names prefixed to different surnames, as James _Madison_ and James _Monroe_. But in the Sovereigns of England, from William I. to Victoria, we have many Christian names alike, and the differences indicated by _ordinal_ numbers, as George I., George II., George III., George IV. This order of the English Kings is most extraordinary, neither the Popes of Rome, nor the French, nor any other list of kings, furnishing any parallel in more than a few incidents. It is these unique coincidences and recurrences that make it so easy to find relations between these sovereigns. This method is not applicable to the American Presidents, Prime Ministers of England, or hardly any other series. (3) No accidental relations of parts of names is resorted to, as was done in the case of the American Presidents. (4) The series is so taught that it can be recited forwards and backwards--the only true test of learning any series. (5) The series is completely worked out and nothing is left to chance or possible mistakes so liable to be committed by novices in dealing for the first time with a new process that has to be applied to many details. (6) When the series is carefully studied and the relations painstakingly _characterised_, it is quickly learned and it is hard to forget. (7) When the series is learned by this method and the relations are occasionally reviewed and _identified_, its recital both ways once or twice a day for a month helps to develop the Attention as well as the Assimilative powers. (8) The _exact name_ of each Sovereign is learned. The student relies on real relations and names, and not on unidentified jingles of threes and threes and twos and twos, like three Edwards and three Henrys and two Edwards and two Henrys, with the inevitable necessity of having afterwards to learn _which_ Edward and _which_ Henry was meant, &c. But summations can follow specifications.
