They he been used by all historians of the times, and there is no8 intention of repeating here fully the oft-told story divulged by these curious declarations. It is needless to say that they disclose scandalous treatment of a young and sensitive girl both by Seymour and Catharine Parr, even after allowing for the free manners then prevalent. It is difficult to understand, indeed, what can he been Seymour’s real intention towards the Princess, unless it was the guilty satisfaction of his own passions. His wife was young and healthy, and in the natural course of events might he been expected to live long, so that he could hardly he looked forward to his marriage with Elizabeth; and yet Mrs. Ashley,3 her governess, confessed in the Tower in February, 1549, that Seymour was in the habit of visiting the girl’s bedroom before she was dressed, sometimes by himself and sometimes with his wife, a

with Charles IX. hing served their pure were now quite at an end, and the Queen of Scots’ determination to take Darnley had further simplified the situation, so that Leicester’s chance was better than ever it had been, supported as he was, for interested reasons, both by France and Spain, the promotion of the Archduke’s suit being mainly pushed in the English Court by those who were Leicester’s declared enemies, whilst the Spanish ambassador was only giving it half-hearted countenance. Norfolk and Sus, however, continued to talk to the Queen about the Archduke, and in a conversation with Sus on the subject she told him that “Robert pressed her so that he does not lee her a moment’s peace.” When Leicester urg
