March 9th, 1933. This morning I took souvara for the first time, dissolving the proper amount in pure distilled water as I had been instructed to do. Afterward I leaned back easily in my chair, breathing with a slow, regular rhythm. I had no preconceived idea of the sensations that would mark the drug's initial effect, since these were said to vary prodigiously with the temperament of the users; but I composed myself to await them with tranquility, after formulating clearly in my mind the purpose of the experinent. For a while there was no change in my awareness. I noticed a slight quickening of the pulse, and modulated my breathing in conformity with this. Then, by slow degrees, I experienced a sharpening of visual perception. The Chinese rugs on the floor, the backs of the serried volumes in my bookcases, the very wood of chairs, table and shelves, began to exhibit new and unimagined colors. At the same time there were curious alterations of outline, every object seeming to extend itself in a hitherto unsuspected fashion. Following this, my surroundings became semi-transparent, like molded shapes of mist. I found that I could see through the marbled cover the illustrations in a volume of John Martin's edition of Paradise Lost, which lay before me on the table.
