Mr. Seward to Mr. Dayton.

No. 42.]

Sir: * * * * * * * *

You will learn from a distinct despatch, No. 41, which accompanies or which will soon follow this, that our negotiation in England has taken a new phase, which, of course, will soon present itself in discussion with the French government.

Treason was emboldened by its partial success at Manassas, but the Union now grows manifestly stronger every day. Let us see how Great Britain will explain.

I am, sir, respectfully, your obedient servant,

WILLIAM H. SEWARD.

William L. Dayton, Esq., &c., &c., &c.
