Mesmerism was introduced into England in the year 1788, by a Dr. De Mainauduc, who, on his arrival at Bristol, delivered lectures on ‘Animal Magnetism’; and, as his somewhat cautious biographer, Dr. George Winter, observes, he ‘was reported to have cured diseased persons, even without the aid of medicines, and of his having the power of treating and curing diseased persons at a distance.’ He found many dupes, for the said authority remarks, ‘On looking over the lists of Students that had been, or then were under the Doctor’s tuition, it appeared that there was 1 Duke—1 Duchess—1 Marchioness—2 Countesses—1 Earl—1 Lord—3 Ladies—1 Bishop—5 Right Honourable Gentlemen and Ladies—2 Baronets—7 Members of Parliament—1 Clergyman—2 Physicians—7 Surgeons—exclusive of 92 Gentlemen and Ladies of respectability, in the whole 127.

‘Naturally fond of study, and my thirst after knowledge being insatiable, I also was allured to do myself the honour of adding my name to the list; and to investigate this very extraordinary Science: and, according to the general terms, I paid 25 Guineas to the Doctor, and 5 Guineas for the use of the Room; I also signed a bond for £10,000, and took an affidavit that I would not discover the secrets of the Science during the Doctor’s natural life.’

So we see that this wonderful power had a market value of no mean consideration, and, indeed, an anonymous authority, who wrote on ‘Animal Magnetism,’ states that Dr. Mainauduc realised £100,000. So lucrative was its practice, that many pretenders sprung up, notable one Holloway who gave lectures at the rate of five guineas the course, besides Miss Prescott, Mrs. Pratt, Monsieur de Loutherbourg the painter, Mr. Parker, and Dr. Yeldal; but the chief of these quacks was Dr. Loutherbourg, who was assisted in his operations by his wife. A book about his wonderful cures was written by one of his believers, Mary Pratt, ‘A lover of the Lamb of God,’ in which he is described as ‘A Gentleman of superior abilities, well known in the scientific and polite Assemblies for his brilliancy of talents as a Philosopher, and Painter: this Gentleman is no other than Mr. De Loutherbourg, who with his Lady, Mrs. De Loutherbourg, have been made by the Almighty power of the Lord Jehovah, proper Recipients to receive divine Manuductions, which heavenly and divine Influx coming from the Radix God, his divine Majesty has most graciously condescended to bestow on them (his blessing) to diffuse healing to all who have faith in the Lord as mediator, be they Deaf, Dumb, Lame, Halt, or Blind.’

That thousands flocked to these charlatans is undoubted, for Dr. George Winter (above quoted) says, ‘It was credibly reported that 3,000 persons have attended at one time, to get admission at Mr. Loutherbourg’s, at Hammersmith; and that some persons sold their tickets for from One, to Three Guineas each.’ And this is corroborated by crazy Mary Pratt. ‘Report says three Thousand People have waited for Tickets at a time. For my own part, the Croud was so immense that I could with difficulty gain the Door on Healing Days, and I suppose, upon conviction, Report spoke Truth.’ De Loutherbourg charged nothing for his cures, and Mary Pratt is extremely scandalized at those who, having received a ticket gratis, sold them from two to five guineas.

Many cases are given in her book of the cures effected by this benevolent couple; how the blind were made to see, the deaf to hear, the lame to walk, or the dumb to speak—nay, could even cast out devils—as the following testimonial will show.

‘The second case I shall mention is that of a woman possessed with Evil Spirits, her name Pennier, lives at No. 33 Ogle Street, Mary-le-bone, near Portland-Chapel; her husband lives with the French Ambassador: her case was too terrific to describe; her eyes and mouth distorted, she was like a Lunatic in every sense of the word; she used to say that it was not her voice that spoke, but the devil in her. In short, her case was most truly distressing, not only to her family, but the neighbourhood; she used to invite people in with apparent civility, then bite them, and scratch like a cat; nay, she would beg a pin of women, and then scratch them with it, &c., &c., &c.’

‘Mrs. De Loutherbourg, a lady of most exquisite sensibility and tenderness, administered to this Mrs. Pennier; she daily amended, and is now in her right mind, praising God, who has through his servant performed such an amazing cure, to the astonishment of hundreds who saw her and heard her.’

Mrs. De Loutherbourg’s system of cure was extremely simple, as this example will show: ‘Mrs. Hook, Stable Yard, St. James’s, has two daughters, born Deaf and Dumb. She waited on the Lady above mentioned, who looked on them with an eye of benignity, and healed them. (I heard both of them speak.)’

Her husband’s plan was rather more clumsy. He imposed hands. ‘A News-Carrier at Chelsea cured of an Abscess in his Side. Mr. De Loutherbourg held his hand on the Abscess half a minute, and it broke immediately.’

Perhaps these cures were not permanent, for ‘Mr. De Loutherbourg told me he had cured by the blessing of God, two Thousand since Christmas. But, as our Lord said, of the ten healed, one only returned to thank him; so many hundreds have acted, that have never returned to Mr. De Loutherbourg.’
