It appears to me that the two indispensable elements of fine acting are a certain amount of poetical imagination and a power of assumption, which is a good deal the rarer gift of the two; in addition to these, a sort of vigilant presence of mind is necessary, which constantly looks after and avoids or removes the petty obstacles that are perpetually destroying the imaginary illusion, and reminding one in one's own despite that one is not really Juliet or Belvidera. The curious part of acting, to me, is the sort of double process which the mind carries on at once, the combined operation of one's faculties, so to speak, in diametrically opposite directions; for instance, in that very last scene of Mrs. Beverley, while I was half dead with crying in the midst of the real grief, created by an entirely unreal cause, I perceived that my tears were falling like rain all over my silk dress, and spoiling it; and I calculated and measured most accurately the space that my father would require to fall in, and moved myself and my train accordingly in the midst of the anguish I was to feign, and absolutely did endure. It is this watchful faculty (perfectly prosaic and commonplace in its nature), which never deserts me while I am uttering all that exquisite passionate poetry in Juliet's balcony scene, while I feel as if my own soul was on my lips, and my color comes and goes with the intensity of the sentiment I am expressing; which prevents me from falling over my train, from setting fire to myself with the lamps placed close to me, from leaning upon my canvas balcony when I seem to throw myself all but over it. In short, while the whole person appears to be merely following the mind in producing the desired effect and illusion upon the spectator, both the intellect and the senses are constantly engrossed in guarding against the smallest accidents that might militate against it; and while representing things absolutely imaginary, they are taking accurate cognizance of every real surrounding object that can either assist or mar the result they seek to produce. This seems to me by far the most singular part of the process, which is altogether a very curious and complicated one. I am glad you got my print safe; it is a very beautiful thing (I mean the drawing), and I am glad to think that it is like me, though much flattered. I suppose it is like what those who love me have sometimes seen me, but to the majority of my acquaintance it must appear unwarrantably good-looking. The effect of it is much too large for me, but when my mother ventured to suggest this to Lawrence, he said that that was a peculiarity of his drawings, and that he thought persons familiar with his style would understand it.
