Lord Lyons to Mr. Seward.

Sir: I have the honor to acknowledge the receipt of your note of the 20th instant, with which you were so obliging as to send me a copy of a circular order of the Provost Marshal General, dated the 19th instant, which points out the mode in which persons claiming exemption from the military service on the ground of alienage will be expected to establish their claims.

I have the honor to be, with the highest respect, sir, your most obedient, humble servant,

LYONS.

Hon. Wm. H. Seward, &c., &c., &c.
