A "spiritual medium," Miss A. was "under the control" of Stillman's dead cousin "Harvey." The "possession" seems to have been throughout free from trance. Stillman says:
I asked Harvey if he had seen old Turner, the landscape painter, since his death, which had taken place not very long before. The reply was "Yes," and I then asked what he was doing, the reply being a pantomime of painting. I then asked if Harvey could bring Turner there, to which the reply was, "I do not know; I will go and see," upon which Miss A. said, "This influence [Harvey's. Editor] is going away--it is gone"; and after a short pause added, "There is another influence coming, in that direction," pointing over her left shoulder. "I don't like it," and she shuddered slightly, but presently sat up in her chair with a most extraordinary personation of the old painter in manner, in the look out from under the brow, and the pose of the head. It was as if the ghost of Turner, as I had seen him at Griffiths's, sat in the chair, and it made my flesh creep to the very tips of my fingers, as if a spirit sat before me. Miss A. exclaimed, "This influence has taken complete possession of me, as none of the others did. I am obliged to do what it wants me to." I asked if Turner would write his name for me, to which she replied by a sharp, decided negative sign. I then asked if he would give me some advice about my painting, remembering Turner's kindly invitation and manner when I saw him. This proposition was met by the same decided negative, accompanied by the fixed and sardonic stare which the girl had put on at the coming of the new influence. This disconcerted me, and I then explained to my brother what had been going on, as, the questions being mental, he had no clue to the pantomime. I said that as an influence which purported to be Turner was present, and refused to answer any questions, I supposed there was nothing more to be done.
But Miss A. still sat unmoved and helpless, so we waited. Presently she remarked that the influence wanted her to do something she knew not what, only that she had to get up and go across the room, which she did with the feeble step of an old man. She crossed the room and took down from the wall a colored French lithograph, and, coming to me, laid it on the table before me, and by gesture called my attention to it. She then went through the pantomime of stretching a sheet of paper on a drawing-board, then that of sharpening a lead pencil, following it up by tracing the outlines of the subject in the lithograph. Then followed in similar pantomime the choosing of a water-color pencil, noting carefully the necessary fineness of the point, and then the washing-in of a drawing, broadly. Miss A. seemed much amused by all this, but as she knew nothing of drawing she understood nothing of it. Then with the pencil and her pocket handkerchief she began taking out the lights, "rubbing-out," as the technical term is. This seemed to me so contrary to what I conceived to be the execution of Turner that I interrupted with the question, "Do you mean to say that Turner rubbed out his lights?" to which she gave the affirmative sign. I asked further if in a drawing which I then had in my mind, the well-known "Llanthony Abbey," the central passage of sunlight and shadow through rain was done in that way, and she again gave the affirmative reply, emphatically. I was so firmly convinced to the contrary that I was now persuaded that there was a simulation of personality, such as was generally the case with the public mediums, and I said to my brother, who had not heard any of my questions [He says above that they were mental. Ed.] that this was another humbug, and then repeated what had passed, saying that Turner could not have worked in that way.
