Statutes and full particulars of proceedings are given in _Liber Custumarum_, and curiously enough no other evidence of the existence of such a fraternity in England is known. From this document we learn that the society had received from the city great privileges in respect of the Chapel of St. Mary, in Guildhall, which was building towards the close of the reign of Edward I. Hence the donation in its favour for a chaplain by Sir Henry le Waleys, 1299,[119] who had been Mayor both of London and Bordeaux, and in the latter capacity would be likely to feel an additional interest in this musical society of French merchants and their English friends. The Regulations are very full and explanatory of the various proceedings at the Festival of the Pui, as the following extracts from Mr. Riley's translation of the Latin original will show:-- _As to the yearly election of a Prince._--'The Prince ought to be chosen as being good, and loyal, and sufficient, upon the oath of eleven companions, or of the twelve, to their knowledge, upon their oath, that the Pui may be promoted thereby, and maintained and upheld. And he who shall be chosen for Prince, may not refuse it, upon his oath. And when the old Prince and his companions shall leave to make a new Prince, at the great feast, the old Prince and his companions shall go through the room, from one end to the other, singing; and the old Prince shall carry the crown of the Pui upon his head, and a gilt cup in his hands, full of wine. And when they shall have gone round, the old Prince shall give to drink unto him whom they shall have chosen, and shall give him the crown, and such person shall be Prince.' _Marriage, death and burial of the Members._--'If there be any one of the companions who marries in the city of London, or who becomes a clerk-priest, he ought to let the companions know thereof, and each shall be there according to his oath, if he have not a proper excuse. And the married person ought to give them chaplets, all of one kind; and all the companions ought to go with the bridegroom to church, and to make offering, and to return from the church to the house. And if there be any of the companions of the brotherhood who departs this life and dies, all the companions ought to be there, and to carry the body to church, by leave of the kindred, and to make offering.' _Common hutch._--'There shall be a common hutch of the company of the Pui, in which the remembrances and the revised provisions of the company shall be placed in safe keeping; of which hutch, in the first place, the new Prince, each year after he is chosen, shall have one key; and two companions, by assent of the companions, for such custody chosen, each one key. And that this hutch shall stand in such safe place as the companions shall ordain within the city of London.'
