Sir Theodore Martin shows more zeal than wisdom in his
con- troversy with Mrs. Hardcastle as to the late Lord Lyndhurst's social attitude towards Lord Campbell. In his letter to the Times of this day week, he denies that anything but the most formal visite were exchanged between them. Yesterday Mrs- Hardcastle published the letter to which she had referred, which certainly shows that in 1854, at least, Lord Lyndhurst treated Lord Campbell with cordial familiarity, and invited his visits as a friend, not as a legal colleague. Indeed, we hardly understand Sir Theodore Martin's zeal for his own side of the great cause of Lyndhurst v. Campbell, unless, indeed, it be the zeal of an ardent Conservative for a brilliant quondam chief.
