No. 10.

Earl Russell to Mr. Mason.

Sir: I have the honor to acknowledge the receipt of your letter of the 16th instant, enclosing twelve affidavits made by passengers on board the steamer Margaret and Jessie, respecting the sinking of that vessel by a shot from a United States man-of-war, and I beg leave to thank you for the communication of these papers.

I am, &c.,

RUSSELL.
