appears by the whole transaction, the house of peers assumed an exclusive right of choosing the protector, though, in the act passed to ratify their election, the commons' assent, as a matter of course, is introduced. The last year's precedent was followed in the present instance, excepting a remarkable deviation; instead of the words "during the king's pleasure," the duke was to hold his office "until he should be discharged of it by the lords in parliament."[444] This extraordinary clause, and the slight allegations on which it was thought fit to substitute a vicegerent for the reigning monarch, are sufficient to prove, even if the common historians were silent, that whatever passed as to this second protectorate of the duke of York was altogether of a revolutionary complexion. In the actual circumstances of civil blood already spilled and the king in captivity, we may justly wonder that so much regard was shown to the regular forms and precedents of the constitution. But the duke's natural moderation will account for part of this, and the temper of the lords for much more. That assembly appears for the most part to have been faithfully attached to the house of Lancaster. The partisans of Richard were found in the commons and among the populace. Several months elapsed after the victory of St. Albans before an attempt was thus made to set aside a sovereign, not labouring, so far as we know, under any more notorious infirmity than before. It then originated in the commons, and seems to have received but an unwilling consent from the upper house. Even in constituting the duke of York protector over the head of Henry, whom all men despaired of ever seeing in a state to face the dangers of such a season, the lords did not forget the rights of his son. By this latter instrument, as well as by that of the preceding year, the duke's office was to cease upon the prince of Wales arriving at the age of discretion.
