Mr. Seward to Mr. Stuart.

Sir: I have the honor to acknowledge the receipt of your note of the 3d instant, requesting to be made acquainted with the circumstances which led to the detention of the British bark Rowena at Philadelphia, and to the imprisonment of her master, Captain John Sherwin, in Fort Delaware.

In reply, I have the honor to inform you that a copy of your note has been sent to Major L. O. Turner, associate judge advocate, with a view to an inquiry into the case being set on foot, the result of which, when ascertained, will be communicated to you.

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

WILLIAM H. SEWARD.

Hon. William Stuart, &c., &c., &c.
