No bag having come there was not much material for Despatches so that my labours were not so great as common. Soon after two o’clock I drove once more to Count Vitzthum’s and found him at home. I asked him if he represented Saxe Coburg in any way, and he promptly replied in the negative. I then asked him if he could tell me who did, in London. He said he though Count Bernstorf might. He was not in turn just now, but I could apply to Mr Katto his Secretary. I drove immediately to the Prussian Embassy and found Mr Katto. On my asking him the same questions, he gave the same answer to the first, and to the second, he named Count Vizthum. Thus it is plain that there is nobody. here to take care of this Duchy, which governs a population not so large as our little state of Rhode Island. I returned home and wrote a Despatch to Mr Seward informing him of the vanity of my labors. Towards evening, a solitary walk to Primrose hill. We had to dinner Mr and Mrs Brown Sequard, Mr Lyman and the Revd Mr Weiss. The two latter come to bring out some biographical work, in connection with Mr Theodore Parker. A gentleman called at dinner time, to tell me that he had the care of a Despatch bag, which failed to come on Sunday.423
