SATURDAY.—I am almost a whole day old, now. I arrived yesterday. That is as it seems to me. And it must be so, for if there was a day-before-yesterday I was not there when it happened, or I should remember it. It could be, of course, that it did happen, and that I was not noticing. Very well; I will be very watchful now, and if any day-before-yesterdays happen I will make a note of it. It will be best to start right and not let the record get confused, for some instinct tells me that these details are going to be important to the historian some day. For I feel like an experiment, I feel exactly like an experiment; it would be impossible for a person to feel more like an experiment than I do, and so I am coming to feel convinced that that is what I AM—an experiment; just an experiment, and nothing more.
