A. Conan Doyle in _The Los Amigos Fiasco_ shows supernaturalism based on the effect of electricity on the body, for the lynchers in trying to kill a man by connecting him with a dynamo succeed in so magnetizing him that he can't be killed in any way. Sax Rohmer tells one Fu-Manchu story of a mysterious murder committed by means of an imprisoned gas that escapes from a mummy case and poisons those exposed to it, and, in another, he introduces a diabolic red insect attracted by the scent of a poisonous orchid, that bites the marked victim. Wells's _The Island of Dr. Moreau_ is a ghastly study in vivisection. Two scientists on a remote island with no other human inhabitants try unspeakable experiments on animals, trying by pruning and grafting and training the living tissue to make them human. They do succeed in a measure, for they teach the beasts to talk and to observe a sort of jungle law laid down by man, yet the effect is sickening. The animals are not human and never can be, and these revolting experiments deprive them of all animal dignity without adding any of the human. In the end they revert to savagery, becoming even more bestial than before. The most dreadful biological experiments in recent fiction are described in Arthur Machen's volume of short stories, _The House of Souls_. In one story an operation on the brain enables a victim to "see the great god Pan," to have revelations of ancient supernaturalism wherein Pan and the devil are united in one character. In another, a delicate cutting of the brain removes the soul,--which takes the form of a wonderful jewel,--and utterly diabolizes the character. These curious and revolting stories are advanced instances of scientific diabolism and leave a smear on the mind. They are more horrible than the creation of Frankenstein's man-monster, for here moral monsters are evolved. Medicated supernaturalism associated with prenatal influence occurs in various stories where a supernormal twist is given because of some event out of the ordinary. Ambrose Bierce's _The Eyes of the Panther_, a story of a young woman who is a panther for part of the time as a result of a shock, is associated with the snake nature of Elsie Venner. Barry Pain's _The Undying Thing_ is one of the most horrible of such complications, for because of a mother's fright over a pack of wolves a monster is born, neither wolf nor human, neither animal nor man, neither mortal nor immortal. It is hidden in a secret cave to die, yet lives on, though not living, to fulfil a curse upon the ancient house. A. Conan Doyle's _The Terror of Blue John Gap_ is a story of a monstrous animal, like a bear yet bigger than an elephant, that ravages the countryside. The theory for its being is that it is a survival, in a subterranean cave, of a long-extinct type, from prehistoric times, that comes out in its blindness to destroy. There are other examples of supernormal animals in modern fiction, yet these suffice to illustrate the _genre_.
