In connection with this part of the subject, and to throw a light on the active dangers associated with the practices of some of M. Luys's trained subjects, I think it right here to put on record the literal transcript of a letter I have received since reaching England from one of them (Jeanne), in which she describes the activities of herself and another subject of Dr. Luys's (Clarice), whom he introduced to me at his clinic, who is figured and described in his lectures, and to whom J have already referred:

Monsibeur le Docteur, - Ayant eu l'honneur Samedic dernier de servir de Sujet a une Seance d'hypnotism chez vous, Monsieur le Docteur, j'espere que vous voudrez bien m'excuser, Monsieur le Docteur, la liberte que je prends de vous faire parvenir une petite nomenclature - des experiences et des phenomenes - que Mr. le Dr. Luys obtien, depuis bien tot 7 ans, sur moi.

Voila Mr. le Docteur les phenomenes qu'on obtien tres facilement sur moi - sans jamais les rater. Mr. Le Docteur Luys n'hesitera pas a le confirmer - d'ailleurs j'offre de le prouver - quand on voudra.

Je travail en ce moment comme Sujet (passif) a la Charite avec Mr. le Dr. Louys - et comme Sujet active avec mes sujets - chez moi tons les jours de 2 heures a 6 heures - et dans tous les Salons de la haute Aristocratic Parisienne en soiree hypnotique ou Spirite.

Anciennements Mdlle. Clarice que Samedi Mr. le Docteur j'avais apercue dans votre Salon - a ete employee par moi - pendant 8 mois comme mon sujet J'ai ete force de la conjedier pour un fait - assez serieux. Cette petite dont les aptitudes sont absolument aussi nules que le Cabotinage est grande, profite des visites chez moi de quelques toutes jeunes dames du plus grand monde qui dans l'apres midi venaient me oonsulter et naturellement en cachette de moi, pour grossire ces gages de sujet, cette petite fille, sans conscience vendai de la morphine au morphinomane et de l'opiome aux opiomanes, une de mes cliente, Mme. la Vicomtesse de . . . . devenue absolument opiomane par l'opiom procurai en secret par Clarice a manque payer cela de sa vie. Par un hasard ayant decouvert le verite j'ai mise, Clarice immediatement a la porte. Voila pourquoi j'ai ete desagreablement impressionee voyant cette triste personne singer avec aplond dans le salon de Mr. le Docteur tous ce qu'elle m'avais vu faire etant chez moi.

This letter will indicate some of the characteristics of the favoured patients and trained subjects of Dr: Luys, and a full investigation of the story of which a corner of the veil is thus lifted, might be very useful in the interests of social morality.

Another ramification and extension of the proceedings at the Charite was disclosed to me by the presence at one of the sittings of a Madame W., who was apparently much interested in the proceedings, and presented me with her card and invited further acquaintance. I called with M. Cremiere and found her installed at a library and reading room. It was the headquarters not only of profound hypnosis and the great hypnotism, but also of the new magic. Here I was introduced to the literature of occult science, and a ' methodical bibliography' of the same was presented to me, being a critical study of the principal modern works on the subject by a group of occultists under the direction of Dr. Papus, President of the independent group of esoteric studies and director of ' L'Initiation.' The book is interesting in itself, and all the more interesting because Madame W. informed me that Papus, or Dr. Papus, as he is described, is in fact M. Encausse, whom I find described on the title-page of Dr. Luys's journal as 'Chef de Laboratoire de la Charit6.' To those who wish to follow out the curious relationships into which the Chef de Laboratoire of Dr. Luys has entered, this little bibliogrcvphie will be singularly interesting.

It contains in itself a good deal of picturesque and surprising information which makes it quite worth the reading of anyone who is curious about the ramifications of so-called occultism, and the vagaries into which the apostles of mesmerism and hypnotism often allow themselves to wander. The absolute key to occult science is, it appears, to be found in the book entitled 'Le Tarot des Bohemiens, le plus Ancien Livre du Monde & l'Usage Exclusive des Inities,' par Papus. Papus (Dr. Luys's Chef de Clinique) is also the author of 'La Science des Mages, et ses Applications Theo-riques et Pratiques.' This is a little pamphlet, price 50 centimes. In the press is announced to appear immediately a series of books of which the first is entitled 'Erotique, comment on devient Fee.' The author not stated.

Under another rubric are the works on hypnotism.

Hypnotism, it is explained, studies the phenomena produced in certain persons by physical or psychical acts capable of fatiguing and surprising one of the senses. Hypnotisers differ from magnetisers in that they deny the existence of any fluid. The 'Lecons Cliniques' of Dr. Luys are warmly recommended, as are those of Colonel de Rochas, who is described as one of the rare French savams who occupy themselves in a scientific manner with the forces, as yet little known, of Nature and of man. Many new and very curious discoveries on the relations of hypnotism and of the ancient magnetism are brought to light in this work. The journal called 'L'Initiation,' of which M. Papus is the editor, deals with hypnotism, psychical force, theosophy, kabala, gnostics, freemasonry and occult sciences. 1 To read through the whole of this catalogue is like a nightmare. It may be recommended to the Psychical Society. They will learn that, under the name of 'telepathy' and of ' telepathic hallucination,' certain French savans have approached the study of the mysterious phenomena of the communication of thought or of the vision of phantoms, and that 'this study is part of occult science and of spiritism.' Of course I brought this and some of the literature away with me; but as I understood that Madame W., the presiding spirit of this Librairie du Merveilleux, could also undertake to provide subjects for experiment.
