TO THE MEMORY OF DR. LIEBEAULT, OF NANCY, IN ADMIRATION OF HIS GENIUS, THIS BOOK, THE OUTCOME OF HIS TEACHING, IS GRATEFULLY DEDICATED 3f]39iS PREFACE TO THE SIXTH EDITION The fifth edition being exhausted, I have prepared a sixth and probably final one. During the six years which have elapsed since the last edition steady progress has been made in the spread of professional interest in psycho-therapy. Many misconceptions have been swept away, and the practice of hypnotism has become widespread, respectable, and almost humdrum. From it has arisen a new form of psycho-therapy, introduced by Professor Sigismund Freud, of Vienna — Psycho-analysis. I am convinced of the great importance of this form of treatment, and it may take the place of hypnotic suggestion in many obscure and baffling cases, but there is room for both and, I think, for their combination. I have been fortunate in obtaining the collaboration of Dr. Constance Long, who has made an attentive study of Freud's theories, and has considerable experience of their practical application. The chief events concerning us since the last edition are : The lamented death of Sir Francis Cruise, ever our stanch supporter ; the growth of the Psycho-Medical Society, the foundation of which was alluded to in the last edition, and which now numbers over a hundred and fifty members, under the presidency of Dr. T. W. Mitchell, with Dr. Douglas Bryan, of Leicester, as Hon. Secretary ; the establishment of clinics in London and Liverpool for viii PREFACE TO THE SIXTH EDITION the treatment of necessitous patients and the instruction of medical inquirers. I have made a good many alterations in this edition, eliminating and curtailing much which has become com- monplace knowledge, and adding a good deal of matter drawn from my personal experience of thirty years' practice of hypnotism. The book has, always had one object in view : To arouse an interest in the mind of the general practitioner in the study of psycho-therapy, and induce him to use it in his own and his patients' interests. Kindly acknowledgments from hundreds of medical men from all parts of the world afford gratifying proof of the attainment of this purpose. My thanks are due to Dr. Dalrymple Marriner for kindly correcting proofs and other help. C. L. T. 47, Upper Brook Street, London, W. October, 1913. PREFACE TO THE FIRST EDITION In bringing forward this little book on Treatment by Suggestion, I feel that, though I must crave indulgence for the shortcomings of the writer, no apology is necessary for introducing so important a subject. The Nancy treatment has during the last few years attracted so much interest among men of science and members of the medical profession on the Continent, that it seems strange the knowledge of it in this country is almost entirely theoretical. The system of psycho-therapeutics has so far attained its fullest development in Holland, where in every large town it is followed by at least one well- qualified practitioner ; while in Germany, Russia, Sweden, and, indeed, every European country, its position is secured by the support of leading physicians, and by the success attending their practice. In every country, I believe, the introduction of the system was at first opposed by persons who feared the popularization of so potent an agent ; but as the beneficial results of the treatment became manifest opposition decreased, and has now almost died out. This is doubtless due chiefly to the fact that the treatment has not been allowed to fall into the hands of ignorant and unqualified practitioners, but has been accepted by men of high character and professional repute. The dangers of hypnotism have been proved chimerical : in proper hands no undesirable medical results can occur through its practice, and there is, I believe, hardly one authenticated case of its being used for a criminal purpose in the countries where it is most frequently employed by medical men. X PRE FA CE More than this can hardly be said for any system of medical treatment. But while maintaining that hypnotism has been very little used for criminal purposes, we should be foolish to blink the fact that it mi'^ht conceivably, under certain circumstances, be a dangerous weapon in unprincipled hands, and that its injudicious use might lead to physical and mental ills ; but such evil results are in a very great measure preventable. Wherever hypnotism has been largely adopted as a valuable aid in the treatment of disease, its importance has been formally recognized, and its employment by charlatans, either as a toy at public exhibitions, or in unauthorized medical practice, has been prohibited by law. Medical electricity is only now emerging from the limbo of quackery, because for years the medical profession allowed it to be exploited by ' professors,' who used it as a universal remedy in all cases, suitable and unsuitable. The Nancy system has been successful on the Continent because it is practised there by qualified physicians and surgeons, whose knowledge and experience has taught them where the treatment would be likely to succeed, and where it would prove ineffectual. I here advocate its use not as a universal remed}- or as a supplarrter of ordinary medical treatment, but as a powerful auxiliary in combating many forms of disease not readily reached by other means. C. L. T. LONDOX, January i, 1889. FOREWORD By Sir FRANCIS R. CRUISE, M.D. Dr. Charles Lloyd Tuckey asks me to write a short introductory chapter to the fifth edition of his truly monumental work on * Psycho-Therapeutics, or Treatment by Hypnotism and Suggestion.' I do so with great pleasure, although I know it is quite needless. His work treats the subject so fully and satisfactorily I feel that any addition of mine is really out of place. I believe the best course I can adopt is to tell the story of how I came to study hypnotism, to believe in it, and to practise it, as 1 do in all cases which appear to me suitable. In the latter part of the eighties I read a great deal on the subject, mainly owing to the advice of a friend, a very learned clergyman, who was interested by the startling psychological problems it involves touching questions of moral responsibility. My studies included the works of Dr. Lloyd Tuckey, Drs. Liebeault, Bernheim, Fontan, Segard, Moll, and others; and ultimately I was led to the conclusion that the statements made concerning hypnotism were either astounding facts, quite unknown to me, or most audacious falsehoods. Being determined to set my mind at rest, I proceeded to Nancy in June, 1890, and placed myself under the tuition of Drs. Liebeault and Bernheim. Later I came to Paris, and there followed the clinical instruction of Dr. Luys at the Charite, Dr. Auguste Voisin, and Dr. Guinon, Chef de Clinique of M. Charcot at the Salpe- xii FOREWORD triere. Later I studied with M. Berillon at his dispen- sary in Rue des Beaux-Arts. I may now state definite!}- that after this somewhat extended, and I hope unpre- judiced study, I arrived at the conclusion that hypnotism is a marvellous reality — a most extraordinary and interest- ing development of neurological and psychological science, and in certain cases a potent aid in therapeutics. I ma}' add that, while striving to be open-minded, my original inclination was adverse to hypnotism. However, I trust that there are exceptions to Herbert Spencer's dictum that ' where prejudices exist the most obvious facts avail nothing,' and that I may claim to be one of the exceptions. Sir William Crookes's advice should be treasured — namely, * to keep our minds, like the windows of a lodging-house, with a notice written thereon, " Rooms to let." ' I do not intend here to enter upon any full account of the history of hypnotism. Such may be found in all the standard treatises bearing upon the subject. Suffice it to say that, while known and practised, after a fashion, in very ancient times, animal magnetism, so called, was pro- minently revived by Mesmer, who flourished at the end of the seventeenth and commencement of the eighteenth centuries. Later — some sixty or more years ago — Mr. Braid, a Manchester surgeon, reintroduced it, and showed how it might be made practically useful in medicine. Braid has the merit of foreshadowing its true application by combining with mesmeric sleep the manipulation of the diseased parts — the first attempt to use suggestion with artificial sleep. Still later, hypnotism was again brought to the front by Dr. Ambroise Liebeault, of Nancy, to whom we are indebted for its present position and for its establishment on a solid basis of usefulness, by its con- junction with systematic verbal suggestion. Now we see in hypnotism no longer a medical curiosity, but the applica- tion of suggestion during 'provoked sleep.' I think I cannot do better than relate here M. Li6- beault's story, as I heard it from himself, of how he came FOREWORD xiii to combine hypnotism with suggestion, and thereby to revolutionize the treatment of a large class of ailments. M. Liebeault told me that as a young practitioner he was often forcibly struck by the potent effect on patients which he observed to follow the physician's expression of a de- cided opinion, favourable or the reverse. This he rightly attributed to the power of the mind and nervous system upon the physical condition. None of us is ignorant of it. Oftentimes we see patients sink from fright, while others are saved, because they are courageous and deter- mined to recover if they can. Pondering over this problem, Liebeault came to seek in what way he could apply sugges- tion of cure with the utmost possible advantage. After many trials, he discovered that in ' induced sleep ' — hypnosis, in other words — when the personality of the subject is partially or almost completely extinguished, and the imagination set free, suggestion becomes infinitely more powerful than in the waking state. This was Lie- beault's point of departure — this is the essence of modern hypnotism. A careful study of his remarkable essay, ' Le Sommeil Provoque,' published in i88g, will well repay study. In it he summarizes the result of all his published contribu- tions to the subject, which date back to the year iS68. Despite ridicule and neglect, Liebeault, with the earnestness of a true scientist and the disinterested de- votion of his compatriots, worked and worked, until he proved to all candid observers that he had struck upon a mine of wealth in therapeutics, and his method came to be tested and adopted by numbers in France and else- where. His first distinguished pupil — Dr. Henri Bernheim, Physician to the Hopital Civil at Nancy and Professor of the Faculty of Medicine there — took the matter up, and utilized his vast field of observation. The result of his labours is embodied in his exhaustive work, ' De la Suggestion et de ses Applications a la Therapeutique,' published in 1888, and also in a later essay, dated 189 1. xiv FORE WORD The study and practice of hypnotism has gradually spread in France and elsewhere, and now reckons amongst its advocates many illustrious names in France, Belgium, Holland, Swit-^erland, Russia, America, England, and elsewhere. To proceed. Let us suppose ourselves in M. Lie- beault's consulting rooms — dispensary, in fact — in the Rue Bellevue at Nancy. From seven in the morning till noon he worked. He was a remarkably bright, in- telligent old gentleman — simple, kindly in manner, and sympathetic with all his patients, who streamed in to seek his aid, mostly when all other means of cure had failed. There were to be seen countless phases of disease, affecting men and women of all ages and many children. His procedure was as follows: He placed the patients in turn in an easy reclining chair, with their backs to the light, questioned them closely as to their symptoms and sufferings, and then forthwith hypnotized them. His method was to make the subject stare at two of his fingers, which he placed a few inches from their eyes, and as soon as the eyes began to water and the pupils to dilate he suggested ' sleep ' in an emphatic manner, and then closed the eyelids, gently pressing the eyeballs. In nearly every case, sooner or later, the patients passed into sleep — of very varying degree, no doubt ; but to all he suggested verbally that on awakening their symptoms would be improved; at the same time he rubbed strongly the seat of disease. In ten minutes or less he awakened them by fanning the face, and when they were aroused all stated that their symptoms were improved, and they went their way, returning in one or more days, as M. Lie- beault directed. I had the opportunity of interrogating these patients, and found that all had the same story to tell — namely, that after Dr. Liebeault's treatment — short or long, as he required — they were either cured or re- lieved. Many of the cases were incurable, and relief only was possible ; in others the cure was averred to be complete. FOREWORD XV Evidently suggestion thus used was potent for thera- peutics. Such was my experience of M. Li6beault's cHnique at the Rue Bellevue. I am very glad I saw his practice, which I can never forget or fail to appreciate for its high value and deep interest. The only criticism I would venture to make is that he appeared to me to rely too completely on suggestion under hypnotic sleep in the treatment of disease, and but rarely sought any aid from our vast medical armamentarium. I shall not attempt to theorize or offer any explanation of his extraordinary results. I have long ago arrived at that period of mental development — for good or ill — at which I have ceased to attempt explanation. If a body falls to earth I call it, as I have been taught, gravitation. That word expresses a fact, but explains nothing. I know that quinine lowers temperature and cures some neuralgias, that aloes purges, and that opium checks the purging. Of the why and wherefore I know nothing. So I also must acknowledge the power of suggestion in hypnosis. If I must theorize on this point I would do so by analogy. Quinine alters the circulation in the brain and nervous system, and thus, I presume, alters the condition of the brain, which is necessary for the sensation of pain. May it not be so of hypnosis ? Obviously, this theory merely puts back the difficulty a stage. Explanation there is none, no more than of the countless processes of physical science which we see pass before us daily. It seems to me more profitable, with our present means of knowledge, to observe and treasure up facts, especially when they help us to cure or relieve disease. Behind all physical phenomena is the Almighty Power that works and directs them, and teaches us — if we are wise — how little we know beyond mere ultimate facts and the generalization therefrom. I think it was the late Duke of Argyll who said : ' Nature, properly interrogated, tells us much of how, when, and where ; but when asked why, she is silent.' Now let me bring my reader to visit M. Bernheim at xvi FOREWORD the Hopital Civil. He is one of the most trusted and prominent medical men in Nancy, and physician to the great hospital of that city. At first he was an absolute sceptic regarding hypnotism and suggestion, but was in- duced to try it after seeing the strange and unexpected cures worked by his friend Li^beault. After some ten thousand experiments he became a firm believer in it, especially in certain cases, and he uses it on a large scale. His practice differs from that of Li^beault in this : that he merely adds hypnotism and suggestion — the latter especially — as an adjunct to other therapeutic agencies. Let us follow him during the visit to his huge wards, filled with every possible form of malady. He treats disease as we physicians all do. For pneumonia he pre- scribes quinine and poultices ; for rheumatism, the sali- cylates ; for phthisis, cod-liver oil and phosphates, and so on. But for many cases, if he thinks it desirable, he adds hypnotism and suggestion. To the sleepless pneumonic patient, to whom he dares not give opium, he administers hypnotism and suggestion of sleep. The patient generally responds and sleeps. The rheumatic patient finds relief of his pains, the phthisical of his cough, and other dis- tressing symptoms. In dealing with patients whose ailments are essentially neurotic he relies mainly on hypnotism. By it he rapidly cures their neuralgias, functional paralysis, hysterical crisis, writer's cramp, insomnia, etc. ; lessens and post- pones, and sometimes cures, epileptic convulsions and other analogous troubles. Of these effects I speak as an eye-witness. With dipsomaniacs he suggests the horror of stimu- lants, and in a large proportion of cases when they awaken there remains a dislike of what previousl}' had been their absorbing passion. My subsequent experience leads me to the opinion that when the patient is really anxious to be cured of dipsomania, and when the sur- roundings are good and helpful, hypnotism is most useful. My friend Dr. J. J. Murphy can bear me out as regards FOREWORD xvii one striking cure under our care. In many other vicious habits, respecting which it is too common with physicians to overlook the physical element, like good results are obtainable. In certain mental failures remarkable cures are . obtained. Some years ago I succeeded after three months' treatment in curing a bad case of kleptomania in a youth. Dr. Lloyd Tuckey gives a similar one at p. 328 of this work, and Dr. Berillon records another in the number of the Revue de VHypnotisme of December, 1906. M. Bernheim does not for a moment pretend that hypnotism can cure organic diseases, such as cancer, phthisis, paralysis from cerebral effusion, with destruction of motor centres ; but even in such cases it often relieves the most distressing symptoms. I have myself seen it relieve pain in hopeless cancerous disease. The special field for treatment by hypnotism is non-organic functional disease, and we all know how rebellious ailments of that nature are to ordinary medication. Strange as this may appear at first sight, a little reflection prepares us to understand the fact. We know how remarkably diges- tion, assimilation, and nutrition are influenced by mental conditions. Should not this prepare us for much more ? ^i Like the late Dr. Liebeault, Dr. Bernheim is delighted to see visitors, and is most attentive to them. After a short time he taught me how to hypnotize, and allowed me to operate on his patients before the class. I soon made the observation, which I confirmed later in Paris, that operators vary a great deal in their power. Some succeed at once, others more slowly, and a few fail alto- gether. Patience, kindness, and a firm will appear indis- pensable. It would be impossible in the short space at my dis- posal to describe even a fraction of the cases I saw and noted in Bernheim's wards during my stay at Nancy. I shall only give some details of a few. The first I shall select exemplifies the power of relieving distressing symp- toms in a case of organic disease, and, moreover, illus- trates that very curious state known as somnambulism, b xviii FOREWORD or the deepest degree of induced sleep. The patient was a man aged forty-two, a soldier discharged from the army owing to disease of the aortic valves, or, as M. Bernheim correctly termed it, ' la maladie de Corrigan.' The ail- ment was not far advanced, and the patient's troubles were mainly insomnia and dyspnoea. Hypnotism, with suggestion of sleep and facility of respiration, gave marked relief, and was repeated whenever the effect wore off. One day M. Bernheim said to me : ' I will now show you a real hypnotic somnambulist.' The patient having been hypnotized, M. Bernheim suggested to him as follows : ' Sleep for ten minutes, then get up, walk across the ward to No. 15, take the nightcap of the patient there, place it under your own pillow, then open the window, and you will hear music' We left the man sleeping. In just ten minutes he arose, crossed the ward slowly and carefully, his eyes being closed, took the nightcap from bed No. 15, brought it over and placed it under his own pillow. He then went to the window, threw it open, and leant out. His face expressed keen delight, and he remained standing until M, Bernheim woke him by blowing on his eyelids. When questioned about the nightcap he was astonished, knew nothing about it ; and when asked ^why he stood at the open window, replied : ' I thought I was back with my regiment, and that the band was playing.' His sleep being of the deepest kind — somnambulistic, in fact — he had not the faintest recollection of the suggestion which caused him to go through the evolutions described. This was one of many similar cases I saw in the services of Drs. Bernheim and Liebeault. I shall now recount the cure of a fi.xed neuralgia of long duration accomplished by suggestion under hyp- notism. One morning while on his rounds M. Bernheim found a new patient just received into hospital. He was a bronzed, weather-beaten man about fifty years of age — a workman in one of the iron foundries which abound FOREWORD xix near Nancy. He complained of a fixed pain in the region of the right false ribs, just over the liver. This pain came on suddenly about a year before, while he was making great exertion in lifting a heavy bar of iron. It was constant, disabling him from working, undermining his health, and reducing him to poverty. He had undergone much treatment, and the affected region bore evidence of severe counter-irritation in the cicatrices caused by the - actual cautery, of which our French brethren are fond. The whole side was so tender that he could barely allow us to examine it. M. Bernheim said to me across the bed : ' I am glad you are here to-day. This is a case in which I expect a very good result from hypnotism.' He then hypnotized the patient, and suggested that on awaking the pain would be better, and at the same time rubbed strongly over the affected parts. In ten minutes he returned and awakened the patient. The pain was gone ! The side was so insensible that vigorous palpation elicited no complaint. This patient was a deep sleeper, or somnambulist. He had no recollection of having even seen M. Bernheim or me. I asked M. Bernheim what explanation he could offer of such a marvellous result. He replied : * I can give none satisfactory. If I must propose any I would say that, as the pain was felt in the brain, the cauteries, etc., merely fixed it there, and that hypnotism has so altered the cerebral condition that sensibility is lost.' I had the opportunity of watching the progress of the case. The pain returned in the evening, but greatly mitigated. A daily repetition of hypnotism gradually extinguished it, and in nine days it was completely gone. All this sounds like a fairy-tale. However, I was able not long after to relieve by hypnotism and suggestion an almost identical neuralgia of long duration in a young girl, which had resisted all other treatment. As in M. Bernheim's case, the pain returned in a mitigated form ; but after five repetitions of the hypnosis and XX FOREWORD suggestion a full week's relief ensued, and the girl went home. This patient was in the Mater Misericordiae Hospital, under the care of my colleague, Dr. Joseph Redmond, now President of the Royal College of Physicians in Ireland. He can bear me out in what I state. The cure has been permanent. This is one of the many successes I have had. Dr. Charles Fitzgerald tells me he has cured by hypnotism and suggestion a case of tinnitus aurium when all other treatment failed. Drs. Richard Hayes, McCullagh, and J. J. Murphy have also had some remarkable results. Thus far I have drawn a very imperfect sketch of what I saw at Nancy with Drs. Li^beault and Bernheim, and I must now leave them. When parting, M. Bernheim gave me a few words of advice, kindly and emphatic. He said that he had taught me all he could within the limits of my visit, and that he could teach me no more unless I remained with him for three or four months. ' You must now learn,' he said, ' the rest by your own experience. Remember, above all, that suggestion is the basis of the new departure. You must learn to dominate by your will-power those whom you treat. When you can hypnotize them (and with perseverance you can do so with much the greater number) your capacity to benefit your patients will grow proportionately.' I not only believe him, but have found untold value in his instructions, and also the solution of much that was previously quite inexplicable. The present is no fit place to dilate upon his idea, but I cannot avoid hinting that it elucidates much that has been hitherto mysterious. For example, the effects of metallo-therapy, homoeopathy, electro-homceopathy, 'faith cure,' and so forth. I now believe that suggestion, plus receptivity, is the foundation of all. I regret that from want of space I dare not attempt here to open up the wide field of deeply interesting study offered by the marvellous effects of suggestion, auto- suggestion, hypnotic and post-hypnotic suggestion. The FOREWORD xxi more I have studied these problems, the more convinced I have become that at present we are quite unable to define the power and limits of suggestion, both in medicine and outside of it. From Nancy I betook myself to Paris, and there followed the clinical teaching of Drs. Luys, Auguste Voisin, Guinon, and Berillon. I found each most in- structive in its special line, and particularly that of Dr. Berillon. But it is time for me to close this little introduction to Dr. Lloyd Tuckey's work. I must not trespass on the reader's patience by details of all I witnessed in Paris. Those who wish can see them in a paper I read before the Medical Section of the Royal Academy of Medicine in Ireland, April 17, 1891, and which was published in the Dublin Journal of Medical Science, May i, i8gi. On my return home after my studies in Nancy and Paris, and ever since, I have practised hypnotism in the cases which appeared to me suitable, and in a large pro- portion of them with most satisfactory results. I have already mentioned my success in a bad case of dipso- mania, in conjunction with Dr. J. J. Murphy. This is only one of many. I have also referred to the remark- able cure of kleptomania in a schoolboy, and of a fixed neuralgia of some standing. I have succeeded also in many cases of insomnia ; in the correction of various bad habits ; in cases of nerve crises, such as fear of crowds, and so forth ; also in various cases of nerve troubles, physical and mental, and m the relief of pain, even when due to organic disease. In one case I suc- ceeded in curing a surgeon of a nervous condition which disabled him from operating. This patient was sent to me by a medical friend of his who had failed to cure him by drugs. The cure has been perfect and permanent. In a case of diabetes I found marked reduction of the excretion of urine and sugar follow hypnotism and sug- gestion. Doubtless this was a case in which the neurotic element predominated. In two cases of somnambulism xxii FOREWORD the effect was striking : one was completely and per- manently cured ; the other is under treatment still, and remarkably improved, though it is of very old standing. As already stated, I have practised hypnotism since 1891, adopting M. Bernheim's doctrine that it is the duty of a physician to do all in his power to cure his patient (see p. 131 of this work). If he understands hypnotism, he will meet many cases m which it is invaluable. It has often struck me that most successful physicians practise hypnotism — at least, that element included under the term * suggestion ' — unconsciously. When I was ver}- young, I frequently met two great Irish physicians, who used to impress on me the importance of a cheerful, con- fident manner, and I recollect one of them saying to me : ' Remember that to inspire a patient with hope and con- fidence is as valuable a stimulus towards recovery as half the drugs in the Pharmacopoeia.' Now that I am old, I understand how right and wise he was. This was treat- ment by suggestion. When I read the paper mentioned before the Ro}al Academy of Medicine in Ireland, I was earnestly and kindly warned to abandon a dangerous subject, and the example was held up of a great London physician who, years ago, met his ruin by espousing the kindred subject of mesmerism. However, I felt no misgiving. I had learned a new means of treating a class of disease quite beyond the reach of drugs, and I refused to give it up. I had no interest or purpose to serve, save truth and the relief of suffering. I have had no reason to regret my decision. So far from injuring me, the result has been exactly the reverse. The modern mind has expanded with the advance of science, and, although conservative and slow, has outlived many prejudices. If my time permitted me, I would practise hypnotism far more freely than I am now able to do. We are upbraided occasionally by weak-minded folk who say that hypnotism is sometimes allied with quackery and charlatanism. Be it so. It is all the more the special duty of the physician to rescue it from such evil FOREWORD xxiii surroundings, and to place it in its true position. As we make it, so it shall be. It may be well now to consider the objections which are occasionall}^ raised against hypnotism. These may be classified as — (a) Those of a physical nature, and (b) Those based on moral grounds. (a) As regards the former, we have the evidence of experts of large experience, such as Liebeault, Bernheim, Forel, Voisin, and others, and they assure us that such objections are groundless. If accidents have arisen, it was only in the hands of unskilled non-medical operators. So far as I am aware no case has been recorded of injury to a patient's health where hypnotism was used by a skilled physician. (6) Passing on to the objections which may be urged against hypnotism upon the score of morality, I feel that I tread upon delicate ground. There is no doubt that it is a very serious matter to submit our free-will to the domination of another, and, as it were, to confide ourselves into his hands. Nevertheless, we freely consent without hesitation to do this every day when we take anaesthetics, such as chloroform, ether, methylene, or nitrous oxide gas. The reason we do not shrink is because we always make sure to entrust ourselves to those in whom we have full confidence. Why should not the same precau- tion justify us in submitting ourselves or our patients to hypnotism ? Even granting, which I do, that the surrender of will and action in hypnosis is greater than in the case of ordinary anaesthetics, the decision must be similar, and is summed up in the sentence, ' Take great care whom you allow to hypnotize you.' Bernheim lays down three rules which seem to include all needful precaution on the part of the hypnotizer. Let me quote them : I. Never hypnotize any subject without his or her formal consent, or the consent of those in authority over him or her. xxiv FOREWORD 2. Never induce sleep except in the presence of a third party. Thus any accusation or trouble may be avoided. 3. Never make any suggestions to the hypnotized subject except those necessary for cure. It seems to me that the ver}- dangers which might arise by the use of hypnotism in evil hands should impel all physicians who naturally wish to use this potent remedy honestly and for the highest ends to take up its study and practice, and carry it out with due honour and tidelity to a great trust. Satisfied as I am that hypnotism is a reality, a potent means towards cure, one which can never be crushed by ignorant and baseless criticism, I hold that it is our duty — imperative duty — to do it justice, and rescue it from unworthy hands. As wc use it, it will be good or evil. I have treated this aspect of the subject fully in my essay of 189 1. It is very gratifying to find that due honour has been paid by the citizens of Nancy to their great towns- man, whose worth they have immortalized by naming after him the Rue Bellevue, the scene of his labours and triumph. It is now the Rue Liebeault. When espousing hypnotism in 1891, I was quite pre- pared to find my statements received with incredulity, and even derision. Had I not studied the subject prac- tically, I should have been sceptical myself. I am rejoiced to see that a society has been inaugurated in England especially devoted to psycho-therapeutics, and that its first President is, most wisely and justly. Dr. C. Lloyd Tuckey. All this looks well, and I think justifies my advice to those who are in doubt (as I once was) to do as I did, and to go and study the subject practically where it is worked out on a large scale. Then they will be capable of form- ing a. just judgment. FRANCIS R. CRUISE, M.D. DUHLIN, A/
