Lord Lyons to Mr. Seward,.

Sir: I have the honor to acknowledge the receipt of your note of the day before yesterday, enclosing a copy of a despatch from Mr. J. Q. Howard, consul of the United States at St. John, New Brunswick, relative to the passage through that city of unusual numbers of persons hostile to the United States en route for Canada. I have, without loss of time, brought the matter to the notice of his excellency the governor general of that province.

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

LYONS.

Hon. William H. Seward, &c., &c., &c.
