It was in this room and at the apothecary Glazer’s that Sainte-Croix made his experiments; but in accordance with poetical justice, the manipulation of the poisons proved fatal to the workers themselves. The apothecary fell ill and died; Martin was attacked by fearful sickness, which brought, him to death’s door. Sainte-Croix was unwell, and could not even go out, though he did not know what was the matter.
