mother was present, and in a few seconds I made up my mind that she was trying all she knew to mislead her mother and prevent her from being anxious. I have no doubt she guesses, if she does not know, what need of caution there is. We lunched alone, and as we all exerted ourselves to be cheerful, we got, as some kind of reward for our labours, some real cheerfulness amongst us. Then Mrs. Westenra went to lie down, and Lucy was left with me. We went into her boudoir, and till we got there her gaiety remained, for the servants were coming and going. As soon as the door was closed, however, the mask fell from her face, and she sank down into a chair with a great sigh, and hid her eyes with her hand.

She complains of difficulty in breathing satisfactorily at times, and of heavy, lethargic sleep, with dreams that frighten her, but regarding which she can remember nothing. She says that as a child she used to walk in her sleep, and that when in Whitby the habit came back, and that once she walked out in the night and went to East
