eth by the brothers de Valois, or rather by their intriguing mother, Catharine de Medici, he been related somewhat fully, mainly from the documents in the National Library in Paris, by the Count de la Ferrière,1 and the recent publication of the Spanish State Papers at Simancas of the reign of Elizabeth by the Record Office,2 puts us into session of a vast quantity of hitherto unused material of the highest interest, especially with regard to the matrimonial overtures made by Philip II. and the princes of the house of Austria; whilst the full text of the extraordinary private letters to and from the Queen in relation to the Alen?on match, 1579–82, printed by the Historical5 MSS. Commission from the Hatfield Papers, affords an opportunity of the greatest value for criticising the by-play in this curious comedy. From these sources, from the Walsingham Papers from the French diplomatic correspondence, from the Foreign, Domestic, and Venetian Calendars of State Papers, and from the various contemporary and later chroniclers of the times, it is proed to construct a consecutive narrative of mos

The Swdish ambassador was to he been openly reproved by the Queen before the whole Court, but the Queen thought better of it, and received him in the presence of Gardiner and the21 Marquis of Winchester only. She diissed him curtly—almost rudely—and told him that after committing such a breach of etiquette as to deliver a letter to her sister before presenting his credentials, he had better go home and never come back to England with such a message as that again. Before Feria left England to see his in July, 1558, he visited Elizabeth at Hatfield, and did his best to persuade her that she had all Philip’s sympathy, and that her safe course would be to adhere to the Spanish connection. He was no match for her in diplomacy even then, and got nothing but iles and genial generalities. In November Mary was dying, and Dassonleville, the Flemish agent, wrote to the King begging him to send Feria back again to forward
