William H. Seward to Horatio J. Perry , Esq., & c ., & c ., & c . , Madrid, December 2, 1864

Mr. Seward to Mr. Perry.

Sir:Your despatch of the 8th ultimo, No. 139, which relates to the detention of the Spanish steamer Cicerone by the sloop-of-war Niagara has been received, and your note upon the subject to Mr. Llorente is approved. I had already, before the receipt of your communication, been informed of the circumstances referred to, and had called upon the Secretary of the Navy for fuller information, which, however, has not been furnished.

In a late despatch from our vice-consul at Havana the Cicerone is referred to as a slave trader.

I am, sir, your obedient servant,
