This alarm appears to have soon subsided; for, in the year 1455, King Henry VI., by advice of his council and parliament, granted four successive patents and commissions to several knights, citizens of London, chemists, monks, mass-priests, and others, to find out the philosopher’s stone and elixir, “to the great benefit,” said the patent, “of the realm, and the enabling of the king to pay all the debts of the crown in real gold and silver.” Prinn, in his Aurum Reginæ, observes, as a note to this passage, that the king’s reason for granting this patent to ecclesiastics was, that “they were such good artists in transubstantiating bread and wine in the eucharist, and therefore the more likely to be able to effect the transmutation of baser metals into better.” No gold, of course, was ever made; and next year the king, doubting very much of the practicability of the thing, took further advice, and appointed a commission of ten learned men and persons of eminence to judge and certify to him whether the transmutation of metals were a thing practicable or no. It does not appear whether the commission ever made any report upon the subject.
In the succeeding reign an alchymist appeared who pretended to have discovered the secret. This was George Ripley, the canon of Bridlington, in Yorkshire.
