She could never give any satisfactory account of how she proceeded in forming her opinions of others. The only visible means of arriving at them, which her deafness and dumbness permitted her to use, consisted simply in examination of a stranger’s manner, expression, and play of features at a first interview. This process, however, seemed always amply sufficient for her; and in more than one instance events proved that her judgment had not been misled by it. Her affliction had tended, indeed, to sharpen her faculties of observation and her powers of analysis to such a remarkable degree, that she often guessed the general tenor of a conversation quite correctly, merely by watching the minute varieties of expression and gesture in the persons speaking--fixing her attention always with especial intentness on the changeful and rapid motions of their lips. Exiled alike from the worlds of sound and speech, the poor girl’s enjoyment of all that she could still gain of happiness, by means of the seeing sense that was left her, was hardly conceivable to her speaking and hearing fellow-creatures. All beautiful sights, and particularly the exquisite combinations that Nature presents, filled her with an artless rapture, which it affected the most unimpressible people to witness. Trees were beyond all other objects the greatest luxuries that her eyes could enjoy. She would sit for hours, on fresh summer evenings, watching the mere waving of the leaves; her face flushed, her whole nervous organization trembling with the sensations of deep and perfect happiness which that simple sight imparted to her. All the riches and honors which this world can afford, would not have added to her existence a tithe of that pleasure which Valentine easily conferred on her, by teaching her to draw; he might almost be said to have given her a new sense in exchange for the senses that she had lost. She used to dance about the room with the reckless ecstasy of a child, in her ungovernable delight at the prospect of a sketching expedition with Mr. Blyth in the Hampstead fields. At a very early date of her sojourn with Valentine, it was discovered that her total deafness did not entirely exclude her from every effect of sound. She was acutely sensitive to the influence of percussion--that is to say (if so vague and contradictory an expression may be allowed), she could, under certain conditions, _feel_ the sounds that she could not hear. For example, if Mr. Blyth wished to bring her to his side when they were together in the painting-room, and when she happened neither to be looking at him nor to be within reach of a touch he used to rub his foot, or the end of his mahl-stick gently against the floor. The slight concussion so produced, reached her nerves instantly; provided always that some part of her body touched the floor on which such experiments were tried.
