Throgmorton, about this time, unwilling to intrust to letters the great secrets committed to him, obtained leave, under some pretext, to come over to London.
{1561.} Elizabeth was determined to make advantage of these events against the queen of Scots, whom she still regarded as a dangerous rival.

She saw herself freed from the perils attending a union of Scotland with France, and from the pretensions of so powerful a prince as Francis; but she considered, at the same time, that the English Catholics, who were numerous, and who were generally prejudiced in favor of Mary's title, would now adhere to that princess with more zealous attachment, when they saw that her succession no longer endangered the liberties of the kingdom, and was rather attended with the advantage of effecting an entire union with Scotland.

She gave orders, therefore, to her ambassador, Throgmorton, a vigilant and able minister, to renew his applications to the queen of Scots, and to require her ratification of the treaty of Edinburgh.

But though Mary had desisted, after her husband's death, from bearing the arms and title of Queen of England, she still declined gratifying Elizabeth in this momentous article; and being swayed by the ambitious suggestions of her uncles, she refused to make any formal renunciation of her pretensions.
Meanwhile the queen mother of France, who imputed to Mary all the mortifications which she had met with during Francis's lifetime, took care to retaliate on her by like injuries; and the queen of Scots, finding her abode in France disagreeable, began to think of returning to her native country.

Lord James, who had been sent in deputation from the states to invite her over, seconded these intentions; and she applied to Elizabeth, by D'Oisel, for a safe-conduct, in case she should be obliged to pass through England;[*] but she received for answer, that, till she had given satisfaction, by ratifying the treaty of Edinburgh, she could expect no favor from a person whom she had so much injured.
