“As if the butterfly, like the artist, were conscious of something not entirely congenial in the child's nature, it alternately sparkled and grew dim. At length it arose from the small hand of the infant with an airy motion that seemed to bear it upward without an effort, as if the ethereal instincts with which its master's spirit had endowed it impelled this fair vision involuntarily to a higher sphere. Had there been no obstruction, it might have soared into the sky and grown immortal. But its lustre gleamed upon the ceiling; the exquisite texture of its wings brushed against that earthly medium; and a sparkle or two, as of stardust, floated downward and lay glimmering on the carpet.”
