The late Mr. Charles Peace, an adventurous if acquisitive spirit, who gave up his life in the same manner as the deceased Mr. Haman, worked alone during the long period of his professional existence, and with misleading safety. The illustrious French lady-prophet unwisely did not value this form of security, and so multiplied opportunities of failure. She followed an entirely opposite policy, one which though it doubtless stood by her on many occasions had a fatal weakness. In some ways it may facilitate matters if one is one’s own Providence; such a course avoids temporarily errors of miscalculation or deduction of probable results. And just as the roulette table has certain chances in favour of Zero, there is for the practical prophet a large hazard in that the dead are unable to speak or to renew effort on a more favourable basis. La Voisin, probably through some unfavourable or threatening experiences, saw the wisdom of associating the forces of prediction and accomplishment, and with the readiness of an active personality effected the junction. For this she was already fairly well equipped with experiences. Both as a wife and a lover of warm and voluptuous nature she understood something of the passions of humanity, on both the female and the male side; and being a woman she knew perhaps better of the two the potency of feminine longing. This did not act so strongly in the lesser and more directly commercial, if less uncertain, phases of her art, such as finding lost property, divining the result of hazards, effecting immunity from danger, or the preserving indefinitely the more pleasing qualities of youth. But in sterner matters, when the issue was of life or death, the masculine tendency towards recklessness kicked the beam. As a nurse in active touch with both medical and surgical wants, aims, and achievements, she was at ease in the larger risks of daily life. And after all, her own ambitions, aided by the compelling of her own natural demands for physical luxury, were quite independent, only seeking through exiguous means a way of achievement. In secret she studied the mystery of a toxicologist; and, probably by cautious experiment, satisfied herself of her proficiency in that little-known science. That she had other aims, more or less dependent on this or the feelings which its knowledge superinduced, can be satisfactorily guessed from some of her attendant labours which declared themselves later.
