Mr. Koerner to Mr. Seward.

No. 90.]

Sir:* * * * *

The resolutions of the House of Representatives at Washington, protesting against a monarchy in Mexico, under European auspices, has caused surprise in diplomatic circles and a good deal of sensation in the press. It is generally supposed that the attitude assumed by the House will produce complications with France, and may lead to a war. As far as Spain is concerned, there are in fact very few persons in favor of the new empire under Maximilian; some indeed, who would otherwise have been in favor of French policy in America, and who generally take their ideas from France, being disappointed in this instance because a Spanish prince was not selected.

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

GUSTAVUS KOERNER.

Hon. William H. Seward, Secretary of State, &c., &c., &c.
