The peculiar excellence of her acting lay in the expression of pathos, sorrow, anguish,--the sentimental and suffering element of tragedy. She was expressly devised for a representative victim; she had, too, a rare endowment for her special range of characters, in an easily excited, superficial sensibility, which caused her to cry, as she once said to me, "buckets full," and enabled her to exercise the (to most men) irresistible influence of a beautiful woman in tears. The power (or weakness) of abundant weeping without disfigurement is an attribute of deficient rather than excessive feeling. In such persons the tears are poured from their crystal cups without muscular distortion of the rest of the face. In proportion to the violence or depth of emotion, and the acute or profound sensibility of the temperament, is the disturbance of the countenance. In sensitive organizations, the muscles round the nostrils and lips quiver and are distorted, the throat and temples swell, and a grimace, which but for its miserable significance would be grotesque, convulses the whole face. Men's tears always seem to me as if they were pumped up from their heels, and strained through every drop of blood in their veins; women's, to start as under a knife stroke, direct with a gush from their heart, abundant and beneficent; but again, women of the temperament I have alluded to above have fountains of lovely tears behind their lovely eyes, and their weeping, which is indescribably beautiful, is comparatively painless, and yet pathetic enough to challenge tender compassion. I have twice seen such tears shed, and never forgotten them: once from heaven-blue eyes, and the face looked like a flower with pearly dewdrops sliding over it; and again, once from magnificent, dark, uplifted orbs, from which the falling tears looked like diamond rain-drops by moonlight. Miss O'Neill was a supremely touching, but neither a powerful nor a passionate actress. Personally, she was the very beau ideal of feminine weakness in its most attractive form--delicacy. She was tall, slender, elegantly formed, and extremely graceful; her features were regular and finely chiseled, and her hair beautiful; her eyes were too light, and her eyebrows and eyelashes too pale for expression; her voice wanted variety and brilliancy for comic intonation, but was deep and sonorous, and of a fine pathetic and tragic quality.
