My Lord: I have the honor to inform your lordship that Commander Rolando is supposed to be on his Way north, and that when he arrives, inquiry will be made of him in regard to the authenticity of the intercepted letter, a copy of which accompanied your note of the 4th instant, respecting the case of the Sir William Peel.

I have the honor to be, with high consideration, my lord, your obedient servant,
