Poor Cosmo nearly lost his senses with delight.

She was there once more! Her eyes sought the corner where the skeleton had stood, and a faint gleam of satisfaction crossed her face, apparently at seeing it empty.

She looked suffering still, but there was less of discomfort expressed in her countenance than there had been the night before.

She took more notice of the things about her, and seemed to gaze with some curiosity on the strange apparatus standing here and there in her room.

At length, however, drowsiness seemed to overtake her, and again she fell asleep.
