§ SIR H. DRUMMOND WOLFFSir, having received a private intimation from the right hon. Member for Greenwich that he cannot be present this evening, I beg to give Notice that I shall to-morrow call the attention of the House to a letter, purporting to be addressed to me, published in The Times of this day, and that at the same time I shall ask you, Sir, whether it is in 506 accordance with Parliamentary usage for one hon. Member to write a letter to another while Parliament is sitting, impugning his conduct in debate and to publish it in the Press, without first giving that hon. Member an opportunity of explanation in this House itself.
