These experiments of the hero with his young bride, these attempts to enhance the attraction of her love by the added zest of peculiar natural surroundings, are extremely characteristic. But it is all in vain! The unnatural passion he had once inspired, and to which the very fact of its being unnatural, and, according to human laws, criminal, communicated a strength and a fire which harmonised with the fiery strength of his own nature, has half infected him, has, in any case, made it impossible for him to love again. In his very remarkable farewell letter to Celuta he says that it is this misfortune which has made him what he is; he has been loved, too deeply loved, and that mysterious passion has sealed the fountains of his being although it has not dried them up. "All love," he says, "became a horror to me. I had the image of a woman before my eyes whom none could approach. Although consumed by passion in my inmost soul, I have been in some inexplicable fashion frozen by the hand of misfortune...." "There are," he continues, "some existences so miserable that they seem an accusation against Providence, and should surely cure any one of the mania for life." Even the innate desire to live, the deeply-rooted natural love of life itself, is scorned by him half affectedly, half weariedly, as a _mama_, and is supplanted by a wild Satanic lust of destruction. "I take it," he continues to Celuta, "that René's heart now lies open before you. Do you see what a strange world it is? Flames issue from it, which lack nourishment, and which could consume creation without being satiated, yea, could even consume thee!"

The one wrong which he accuses himself of having done to Celuta is, that he has united her destiny with his. The deepest sorrow this connection has caused him lies in the fact that Celuta has made him a father; it is with a species of horror that he sees his life thus extended beyond its limits. He bids Celuta burn his papers, burn the hut built by him in which they have lived, and return home to her brother. He wishes to leave no traces of his existence upon earth. It is evident that he would fain also require her, after the manner of Indian widows, to lay herself upon his funeral pile; for the same species of jealousy inspires him which prompted many a mediæval knight to kill his favourite horse. This last letter to his wife ends with the following characteristic farewell:--
