Nero into the mildest of men before he has done digesting it, and the morning draught of Alexander the Great shall make Alexander run for his life at the first sight of the enemy the same afternoon. On my sacred word of honour it is lucky for Society that modern chemists are, by incomprehensible good fortune, the most harmless of mankind. The mass are worthy fathers of families, who keep shops. The few are philosophers besotted with admiration for the sound of their own lecturing voices, visionaries who waste their lives on fantastic impossibilities, or quacks whose ambition soars no higher than our corns." In "Armadale," the same novelist introduces us to a poisoner of the deepest dye in the person of Miss Gwilt. This fair damsel, whose auburn locks seemed to have possessed an irresistible attraction for the opposite sex, was addicted to taking laudanum to soothe her troubled nerves, and first tried to mix a dose with some lemonade she had prepared for her husband's namesake and friend, whom she wished out of the way. This attempt failing, and a second one, to scuttle a yacht in which he was sailing, proving futile also, he was finally lured to a sanatorium in London, where she had arranged for him to be placed to sleep in a room into which a poisonous gas (presumably carbonic acid) was to be passed. At the last moment she discovers her husband has taken the place of her victim, and in a revulsion of feeling she rescues him, and ends her own life instead in the poisoned chamber. According to the story, the medical investigation which followed this tragedy ended in discovering that she had died of apoplexy; a fact which had it occurred in real life would not have redounded to the credit of the medical men who conducted it. The heroine of Mr. Benson's novel, "The Rubicon," poisons herself with prussic acid of unheard of strength, which she discovers _among some photographic chemicals_.
