Read it through once

Mrs. Linton sat in a loose white dress, with a light shawl over her shoulders, in the recess of the open window, as usual. Her thick, long hair had been partly removed at the beginning of her illness, and now she wore it simply combed in its natural tresses over her temples and neck. Her appearance was altered, as I had told Heathcliff; but when she was calm, there seemed unearthly beauty in the change. The flash of her eyes had been succeeded by a dreamy and melancholy softness; they no longer gave the impression of looking at the objects around her: they appeared always to gaze beyond, and far beyond—you would have said out of this world. Then, the paleness of her face—its haggard aspect having vanished as she recovered flesh—and the peculiar expression arising from her mental state, though painfully suggestive of their causes, added to the touching interest which she awakened; and—invariably to me, I know, and to any person who saw her, I should think—refuted more tangible proofs of convalescence, and stamped her as one doomed to decay.
