During that year I had seven lower teeth capped in a rather lengthy dental process. This was examined in detail in relation to the later symptom of "tuning" the Second State condition by movements of the jaw. It is possible that the bits of assorted metal comprising part of the tooth-capping fabrication acted electrically or in some other fashion on the brain. This still remains an unexplored possibility. Physicists, physiologists, and electronics specialists have no theory relating to this. Proper research could prove or disprove the hypothesis. There are hundreds of thousands of people walking around with bits of metal in their teeth, and other such incidents have been reported. A survey might prove interesting. There were no other physiological changes significant enough to be recalled consciously. The only above-ordinary nutritional factor was that of vitamin intake. Since my wife believed strongly in nutrition, daily dosages of vitamins A, B complex, C, and E, plus mineral tablets, had been a norm for several years. Again, a cumulative effect could have been the cause, but no reports or research studies indicated any factors resembling the Second State. Other than this, a normal diet was the rule, with no major changes for five years at the least. At the psychological and physical activity levels, there is much to be noted. It is quite conceivable that the causes of the phenomenon lie here. The first consideration might be termed the anesthesia episode, which took place some six months prior to the first symptom. The beginning came when I noticed an unusual "heady" effect from the fumes of a gallon can of contact cement. I was installing a cubbyhole desk top in the wall of a bedroom at home when I became aware of the sensation. The can clearly stated on the lid that the cement should be used in well-ventilated areas. I correctly assumed that this was a fire-hazard warning from the manufacturers. The sensation reminded me of the strange effect I had experienced in the past just as I was "going under" from anesthesia. Curious, I experimented with the effect of the fumes a number of times in the following month, with very significant results. Upon learning that the fuming agents were toluol (a common commercial hydrocarbon detergent) and acetone (once used as anesthetic), 1 made several experiments with the subjective effects of light anesthesia, utilizing a less volatile and relatively safe inhalant, Trilene. In retrospect, the results of these experiments seem to parallel closely the reports of those who have undertaken the LSD experience. Intensely vital and not at all unpleasant, the effects may well have triggered an inner desire or need for experiences beyond those I had had to that date. Reluctantly, I stopped the experiments, as there seemed inherent dangers of physiological side effects if they were continued. Although I had set up rigid controls, there
