Mr. Seward to Mr. Clay.

No. 24.]

Sir: I have received your despatch of the 2d instant, (No. 8) relative to my instruction of the 11th ultimo (No. 342) to Mr. Dayton, in reply to the instruction addressed by Mr. Drouyn de l’Huys to Mr. Mercier, on the 23d of April last, respecting the Polish insurrection.

While this government could not with propriety publish the correspondence, it could not object to its publication by either of the powers to whom it was furnished.

I am, sir, your obedient servant,

WILLIAM H. SEWARD.

Cassius M. Clay, Esq., &c., &c., &c.
