Sir Adam Ferguson is a delightful person, whose quick, bustling manner forms a striking contrast to Walter Scott's quiet tone of voice and deliberate enunciation I have also made acquaintance with Jeffrey, who came and called upon us the other morning, and, I hear, like some of his fellow-townsmen, complains piteously that I am not prettier. Indeed, I am very sorry for it, and I heartily wish I were; but I did not think him handsome either, and I wonder why he is not handsomer? though I don't care so much about his want of beauty as he seems to do about mine. But I am running on at a tremendous rate, and quite forget that I have traveled upward of forty miles to-day, and that I promised my mother, whenever I could, to go to bed early. Good-by, my dear Mrs. Jameson. I hope you will be able to make out this scrawl, and to decipher that I am yours affectionately, F. A. KEMBLE. Of the proverbial frigidity of the Edinburgh public I had been forewarned, and of its probably disheartening effect upon myself. Mrs. Harry Siddons had often told me of the intolerable sense of depression with which it affected Mrs. Siddons, who, she said, after some of her grandest outbursts of passion, to which not a single expression of applause or sympathy had responded, exhausted and breathless with the effort she had made, would pant out in despair, under her breath, "Stupid people, stupid people!" Stupid, however, they undoubtedly were not, though, as undoubtedly, their want of excitability and demonstrativeness diminished their own pleasure by communicating itself to the great actress and partially paralyzing her powers. That this habitual reserve sometimes gave way to very violent exhibitions of enthusiasm, the more fervent from its general repression, there is no doubt; and I think it was in Edinburgh that my friend, Mr. Harness, told me the whole of the sleep-walking scene in "Macbeth" had once been so vehemently encored that my aunt was literally obliged to go over it a second time, before the piece was allowed to proceed.
