Clarendon came here to-day to take leave of me on going to the Conference in Paris. He talks despondingly, but less about making peace than about making one that will be acceptable here. He augurs well from the choice of Russian Plenipotentiaries who are both personally agreeable to him, for he knows Orloff very intimately. When he took leave of Brunnow three years ago he said to him, 'If ever you see a good chance of peace, let me know,' and now Brunnow has sent him a message reminding him of what he had said, and telling him he now saw it. It was Clarendon who fixed on Paris for the Conference, everybody else being against it, especially the Emperor Napoleon and Palmerston, but Clarendon thought the advantage of having personal communication with the Emperor himself outweighed every other consideration, and he is right. Louis Napoleon will be the arbiter, and the struggle will be between England and Russia to get possession of him. Brunnow arrived at Paris to-day, the first arrival of the Plenipotentiaries, and he was received with great acclamations and manifestations of joy. Clarendon is dissatisfied at Brunnow's having got there first as if to steal a march on him, but this is unreasonable, as no particular day was fixed for their coming at once, and Clarendon might have been the first if he had chosen it, and Cavour is to be there to-day or to-morrow.
