The debate took a turn last night we had not at all anticipated. Warre never mentioned Henry Wynn but in terms of civility and courtesy, and not only disclaimed all personal attack against him, but also every imputation against the arrangements which had led to his appointment. Lord Londonderry followed Warre, and explained the case, &c., &c.; and the only other person who took any part in the debate was Lord Normanby, who distinctly also declared against all allusion to the individual who held the appointment; and he had scarcely proceeded thus far before the House became so impatient that he was all but coughed down. Under these circumstances there was no opening for any of us, which for some reasons I regret, though upon the whole nothing could be more satisfactory than the tone and temper of the debate. I think the abstinence from personal attack must have been the result of previous arrangement, probably the more sober ones refused to concur in the vote on any other terms. A weaker case was never made out. Newport stayed away. Calcraft went out just before the division. Talbot, member for the County of Dublin, sent a message to Wynn by Plunket, to say that he would not vote against his brother. Carew, member for the County of Wexford, made a similar communication to me. Neville, I believe, voted with us; and Ebrington stayed away. Holmes told me that twenty-four came to the door after it was closed, of whom nineteen belonged to us. The most serious business we have now to look forward to is the new financial arrangement; and I must own that I dread the difficulties in which Van may involve us. Believe me, your Grace's very faithful, JOSEPH PHILLIMORE. P.S.--The whole debate last night did not occupy two hours. The Catholic Peers' Bill stands for the third reading to-night; it is not to be opposed, at least not by those who have taken the lead against it. I hear that Lords Caledon and Gosford, Gosse and Wilton will vote for the Bill, the two first have hitherto always voted against the Catholics, the two latter have not voted on the question; an Irish bishop is also to vote with us. On the other hand, Lords Camden and Clancarty will not vote, and they have supported always the general measure. The Archbishop of York told me he thought several of the opposers of the general measure would stay away: this, I understand from other quarters, is the course he intends to adopt. Lord Grenville, I believe, will come to London for the debate in the House of Lords. I am afraid that the Bill will not be carried, but I am very sanguine in thinking that the majority in the Upper House will be very considerably diminished. Wilberforce made a point of staying to vote with us last night. THE RIGHT HON. CHARLES W. WYNN TO THE DUKE OF BUCKINGHAM.
