Still more remarkable, however, were the physical changes which I now began to perceive. I found to my horror that at times I was less conscious of myself, of my own existence, than used to be the case. This sensation was so novel, that at first it quite bewildered me. I felt like asking some one constantly if I were really George Dedlow or not; but, well aware how absurd I should seem after such a question, I refrained from speaking of my case, and strove more keenly to analyze my feelings. At times the conviction of my want of being myself was overwhelming, and most painful. It was, as well as I can describe it, a deficiency in the egoistic sentiment of individuality. About one half of the sensitive surface of my skin was gone, and thus much of relation to the outer world destroyed. As a consequence, a large part of the receptive central organs must be out of employ, and, like other idle things, degenerating rapidly. Moreover, all the great central ganglia, which give rise to movements in the limbs, were also eternally at rest. Thus one half of me was absent or functionally dead. This set me to thinking how much a man might lose and yet live. If I were unhappy enough to survive, I might part with my spleen at least, as many a dog has done, and grown fat afterwards. The other organs, with which we breathe and circulate the blood, would be essential; so also would the liver; but at least half of the intestines might be dispensed with, and of course all of the limbs. And as to the nervous system, the only parts really necessary to life are a few small ganglia. Were the rest absent or inactive, we should have a man reduced, as it were, to the lowest terms, and leading an almost vegetative existence. Would such a being, I asked myself, possess the sense of individuality in its usual completeness,--even if his organs of sensation remained, and he were capable of consciousness? Of course, without them, he could not have it any more than a dahlia, or a tulip. But with it--how then? I concluded that it would be at a minimum, and that, if utter loss of relation to the outer world were capable of destroying a man's consciousness of himself, the destruction of half of his sensitive surfaces might well occasion, in a less degree, a like result, and so diminish his sense of individual existence.
