about two years ago, I was taken to see the phenomena which occur under the mediumship of Mrs. Mary Marshall, who then resided at 13, Bristol-gardens, but now at 2, Bennett-strect, St. James’s. Tables and chairs moved about in daylight, and sometimes rose from the ground, whilst at the dark séances voices were heard, and luminous manifestations seen; all these things purported to come from spirits. I therefore re solved to be a constant visitor at the séances, and to stick at the work till I either discovered the assertions to be true, or detected the imposture with sufficient aecuraey and certainty to expose it in the presence of witnesses, and to be able to publish the facts with com plete sectional drawings of the apparatus used. The voice calling itself “ John King” is backed by an intelligence apparently entirely different in kind from that of Mr. or Mrs. Marshall. However, I pri vately assumed that Mr. Marshall did the voice, and by attending a few séances found that it was a common thing for Mr. Marshall and John King to speak at the same time, so I was obliged to throw over that theory. Next I assumed that Mrs. Marshall did it, till one evening I sat next her; she was on my right hand side, I had hold of her hand and arm, and John King came and talked into my left ear, Mrs. Marshall being perfectly motionless all the time, so over went the other theory. Next, I assumed that a confederate, among the visitors to the circle did John King’s voice, so had a séance with Mr. and Mrs. Marshall alone; John was there, and talked for an hour. Lastly, I assumed that a concealed confederate did the voice, so attended two séances where Mrs. Marshall was present among strangers to her, in a strange house, and again John King was as lively as ever. Finally, on Thursday evening, Decem ber 30th, 1869, John King came and talked to eleven persons at Mrs. C. Berry’s circle, in the absence of Mr and Mrs. Marshall, the medium being Mrs. Perrin. I only certify to the genuine character of such of the manifestations as I have tested, and no more, but trust that these facts will clear away some of the doubts in cautiously thrown over Mrs. Mary Marshall’s medium ship by Daybreak and the Spiritual Magazine. THE CURE OF M. LEON FAVRE.—The Revne Spiri tualiste of September last contains an account written by M. Leon Favre, Consul-General of France, narrating how he was cured of a complaint of 42 years standing, by a spirit. He says — "I was in 1826 at Livorno. I was there poisoned by eating of a large sort of lobster, probably cooked in a copper vessel in bad condition. I was saved by medical energy, but the poison left the most terrible effects on my stomach; the most singular symptoms seized me. I had a gastric complaint which lasted seven years, and which was succeeded by nervous maladies strange lethargies, and morbid effects which defied ever scientific remedy. The crises were marked by the most frightful circumstances. Sometimes my eyes were convulsed the pallor of death, overspread my features which were dis torted by the most painful contractions ; my cheeks instantly sunk, all my limbs became rigid ; my body was stretched out like a corpse, I often fell with my head against the wall, and I lay in this state of catalepsy. Sometimes the attack seemed to come down on me like a bird of prey ; my intestines stomach and chest seemed wrenched and twisted violently. The paroxysm lasted for an hour at most, but it left a fearful havoc in the system. Frequently it produced aberrations of vision which caused me te see every object triple, always fol lowed by a prostration and temporary exhaustion of all my He then narrates how in the course of years this cruel forces. malady increased in virulence, and the attacks succeeded each other at shorter intervals. Medical skill failed to remove the disease. At last a spirit, acting through the mediumship of a young schoolmistress of the name of Catarina, prescribed for M. Leon Favre. The spirit "declared his name to be Giacomco Giaferro; that he was born at Venice in 1418, and died in 1510, at the age of 92, at Verona, where he practised medic cine. Generally, medical healers proceed on the system of the somnambules. They inspect the patient and prescribe their remedies without the subject being required to give an explanation. Giaferro acted like a living doctor. The patient gave the history of his complaints without omitting the smallest detail. Giaferro listened scrupulously to the present diagnosis, but he rarely foresaw that which might unexpectedly arise. I assembled often with me three or four physicians to act as a check upon him. I have heard them dispute with him, make fresh consultation of the patient according to his indications, find that they were wrong, and that he (Giaferro) the invisible, was right ! His appreciations were marked by an exactness remarkable, and nearly always I have seen the doctors adopt his opinion in the treatment of the case. It was under the direction of this invisible doctor, at first watched by my friend Cogevina, that I placed myself, as I have said on the 5th of March, 1868. Reversing the method of Mans dorf, he placed the silver on my stomach, and the zinc under the soles of my feet, commencing by an application of ten minutes, which augmented every day by as much additional time, arrived finally at nine hours. During three months examining me every week, oftener twice than once, at first with the concurrence of Dr. Cogevina, then by himself alone he alternated the poles, placing on the stomach sometimes the positive, sometimes the negative, varying the duration of the applications, suspending them occasionally for some days, and taking as the principal basis of his internal treatment bismuth, caleined magnesia, and the codeine of Berthé. At the end of three months he declared that I was cured of my cramps, and that they could never return. He continued, however, till December, the use of the apparatus, increasing progressively the intervals between the applications. He ended by sus pending them altogether. In fact, I was well. Cured by an invisible hand after having suffered 42 years, and having exhausted all known medieal remedies ! It is impossible to retrace here the minnte cares, the extreme tenderness, the expression of love which accompanied this prolonged treat ment. The soul of this man seemed to follow me everywhere, to watch over me, and, let the sceptics smile, to knit up with my own a holy and fraternal relation which my gratitude has sealed for eternity.” M. Leon Favre’s narrative is published in full in the December number of the Spiritual Magazine.
