My dear Sons: . . . Yesterday we dined at Macready's and met quite a new, and to us, a most agreeable circle. There was Carlyle, who talked all dinner-time in his broad Scotch, in the most inimitable way. He is full of wit, and happened to get upon James I., upon which topic he was superb. Then there was Babbage, the great mathematician, Fonblanc, the editor of the EXAMINER, etc.
