4th.  Up, and a while at the office, but thinking to have Mr. Povy’s business to-day at the Committee for Tangier, I left the Board and away to White Hall, where in the first court I did meet Sir Jeremy Smith, who did tell me that Sir W. Coventry was just now sent to the Tower, about the business of his challenging the Duke of Buckingham, and so was also Harry Saville to the Gate-house; which, as [he is] a gentleman, and of the Duke of York’s bedchamber, I heard afterwards that the Duke of York is mightily incensed at, and do appear very high to the King that he might not be sent thither, but to the Tower, this being done only in contempt to him.  This news of Sir W. Coventry did strike me to the heart, and with reason, for by this and my Lord of Ormond’s business, I do doubt that the Duke of Buckingham will be so flushed, that he will not stop at any thing, but be forced to do any thing now, as thinking it not safe to end here; and, Sir W. Coventry being gone, the King will have never a good counsellor, nor the Duke of York any sure friend to stick to him; nor any good man will be left to advise what is good.  This, therefore, do heartily trouble me as any thing that ever I heard.  So up into the House, and met with several people; but the Committee did not meet; and the whole House I find full of this business of Sir W.

[Charles ii. wrote to his sister (Henrietta, Duchess of Orleans), on March 7th, 1669:  “I am not sorry that Sir Will.  Coventry has given me this good occasion by sending my Lord of Buckingham a challenge to turne him out of the Councill.  I do intend to turn him allso out of the Treasury.  The truth of it is, he has been a troublesome man in both places and I am well rid of him” (Julia Cartwright’s “Madame,” 1894, p. 283).]

go to him to know the business; but H. Saville would not tell it to any but himself, and therefore did go presently to the Duke of Buckingham, and told him that his uncle Coventry was a person of honour, and was sensible of his Grace’s liberty taken of abusing him, and that he had a desire of satisfaction, and would fight with him.  But that here they were interrupted by my Lord Chamberlain’s coming in, who was commanded to go to bid the Duke of Buckingham to come to the King, Holmes having discovered it.  He told me that the King did last night, at the Council, ask the Duke of Buckingham, upon his honour, whether
