That I ever breathed again is a tribute to the inherent vitality of the healthy human organism. Often I look back to that night and feel a touch of actual humour in those repeated lapses of consciousness; lapses wdiose succession reminded me at the time of nothing more than the crude cinema melodramas of that period. Of course, it is possible that the repeated lapses never occurred; and that all the features of that underground nightmare were merely the dreams of one long coma which began with the shock of my descent into that abyss and ended with the healing balm of the outer air and of the rising sun which found me stretched on the sands of Gizeh before the sardonic and dawn-flushed face of the Great Sphinx.
