I SAT ONE EVENING IN my laboratory; the sun had set, and the moon was just rising from the sea; I had not sufficient light for my employment, and I remained idle, in a pause of consideration of whether I should leave my labour for the night, or hasten its conclusion by an unremitting attention to it. As I sat, a train of reflection occurred to me, which led me to consider the effects of what I was now doing. Three years before I was engaged in the same manner, and had created a fiend whose unparalleled barbarity had desolated my heart, and filled it for ever with the bitterest remorse. I was now about to form another being, of whose dispositions I was alike ignorant; she might become ten thousand times more malignant than her mate, and delight, for its own sake, in murder and wretchedness.
