Our reader has been told how Mrs. Penthony Morris stormed the Villa Caprini, established herself, child, maid, and Skye terrier within its walls, and became, ere many days went over, a sort of influence in the place. It is not in chemistry alone that a single ingredient, minute and scarce perceptible, can change the property and alter all the quality of the mass with which it is mingled. Human nature exhibits phenomena precisely alike, and certain individuals possess the marvellous power of tingeing the world they mix in, with their own hue and color, and flavoring society with sweet or bitter, as temper induces them. The first and most essential quality of such persons is a rapid--an actually instinctive--appreciation of the characters they meet, even passingly, in the world's intercourse. They have not to spell out temperaments slowly and laboriously. To them men's natures are not written in phonetic signs or dark symbols, but in letters large and legible. They see, salute, speak with you, and they understand you. Not, perhaps, as old friends know you, with reference to this or that minute trick of mind or temper, but, with a far wider range of your character than even old friends have taken, they know your likes and dislikes, the things you fear and hope, the weak points you would fortify, and sometimes the strong ones you would mask,--in a word, for all the purposes of intercourse, they are able to estimate your strength and weakness, and all this ere, perhaps, you have noted the accents of their voice or the color of their eyes.
