How profound that mystery of the Invisible is! We cannot fathom it with our miserable senses: our eyes are unable to perceive what is either too small or too great, too near to or too far from us; we can see neither the inhabitants of a star nor of a drop of water; our ears deceive us, for they transmit to us the vibrations of the air in sonorous notes. Our senses are fairies who work the miracle of changing that movement into noise, and by that metamorphosis give birth to music, which makes the mute agitation of nature a harmony. So with our sense of smell, which is weaker than that of a dog, and so with our sense of taste, which can scarcely distinguish the age of a wine!

     Oh! If we only had other organs which could work other miracles in our favor, what a number of fresh things we might discover around us!

     May 16. I am ill, decidedly! I was so well last month! I am feverish, horribly feverish, or rather I am in a state of feverish enervation, which makes my mind suffer as much as my body. I have without ceasing the horrible sensation of some danger threatening me, the apprehension of some coming misfortune or of approaching death, a presentiment which is no doubt, an attack of some illness still unnamed, which germinates in the flesh and in the blood.

     May 18. I have just come from consulting my medical man, for I can no longer get any sleep. He found that my pulse was high, my eyes dilated, my nerves highly strung, but no alarming symptoms. I must have a course of shower baths and of bromide of potassium.

     May 25. No change! My state is really very peculiar. As the evening comes on, an incomprehensible feeling of disquietude seizes me, just as if night concealed some terrible menace toward me. I dine quickly, and then try to read, but I do not understand the words, and can scarcely distinguish the letters. Then I walk up and down my drawing-room, oppressed by a feeling of confused and irresistible fear, a fear of sleep and a fear of my bed.

     About ten o'clock I go up to my room. As soon as I have entered I lock and bolt the door. I am frightened - of what? Up till the present time I have been frightened of nothing. I open my cupboards, and look under my bed; I listen - I listen - to what? How strange it is that a simple feeling of discomfort, of impeded or heightened circulation, perhaps the irritation of a nervous center, a slight congestion, a small disturbance in the imperfect and delicate functions of our living machinery, can turn the most light-hearted of men into a melancholy one, and make a coward of the bravest? Then, I go to bed, and I wait for sleep as a man might wait for the executioner. I wait for its coming with dread, and my heart beats and my legs tremble, while my whole body shivers beneath the warmth of the bedclothes, until the moment when I suddenly fall asleep, as a man throws himself into a pool of stagnant water in order to drown. I do not feel this perfidious sleep coming over me as I used to, but a sleep which is close to me and watching me, which is going to seize me by the head, to close my eyes and annihilate me.

     I sleep - a long time - two or three hours perhaps - then a dream - no - a nightmare lays hold on me. I feel that I am in bed and asleep - I feel it and I know it - and I feel also that somebody is coming close to me, is looking at me, touching me, is getting on to my bed, is kneeling on my chest, is taking my neck between his hands and squeezing it - squeezing it with all his might in order to strangle me.

     I struggle, bound by that terrible powerlessness which paralyzes us in our dreams; I try to cry out - but I cannot; I want to move - I cannot; I try, with the most violent efforts and out of breath, to turn over and throw off this being which is crushing and suffocating me - I cannot!

     And then suddenly I wake up, shaken and bathed in perspiration; I light a candle and find that I am alone, and after that crisis, which occurs every night, I at length fall asleep and slumber tranquilly till morning.

     June 2. My state has grown worse. What is the matter with me? The bromide does me no good, and the shower-baths have no effect whatever. Sometimes, in order to tire myself out, though I am fatigued enough already, I go for a walk in the forest of Roumare. I used to think at first that the fresh light and soft air, impregnated with the odor of herbs and leaves, would instill new life into my veins and impart fresh energy to my heart. One day I turned into a broad ride in the wood, and then I diverged toward La Bouille, through a narrow path, between two rows of exceedingly tall trees, which placed a thick, green, almost black roof between the sky and me.

     A sudden shiver ran through me, not a cold shiver, but a shiver of agony, and so I hastened my steps, uneasy at being alone in the wood, frightened stupidly and without reason, at the profound solitude. Suddenly it seemed as if I were being followed, that somebody was walking at my heels, close, quite close to me, near enough to touch me.

     I turned round suddenly, but I was alone. I saw nothing behind me except the straight, broad ride, empty and bordered by high trees, horribly empty; on the other side also it extended until it was lost in the distance, and looked just the same - terrible.

     I closed my eyes. Why? And then I began to turn round on one heel very quickly, just like a top. I nearly fell down, and opened my eyes; the trees were dancing round me and the earth heaved; I was obliged to sit down. Then, ah! I no longer remembered how I had come! What a strange idea! What a strange, strange idea! I did not the least know. I started off to the right, and got back into the avenue which had led me into the middle of the forest.

     June 3. I have had a terrible night. I shall go away for a few weeks, for no doubt a journey will set me up again.

     July 2. I have come back, quite cured, and have had a most delightful trip into the bargain. I have been to Mont Saint-Michel, which I had not seen before.

     What a sight, when one arrives as I did, at Avranches toward the end of the day! The town stands on a hill, and I was taken into the public garden at the extremity of the town. I uttered a cry of astonishment. An extraordinarily large bay lay extended before me, as far as my eyes could reach, between two hills which were lost to sight in the mist; and in the middle of this immense yellow bay, under a clear, golden sky, a peculiar hill rose up, somber and pointed in the midst of the sand. The sun had just disappeared, and under the still flaming sky stood out the outline of that fantastic rock which bears on its summit a picturesque monument.

     At daybreak I went to it. The tide was low, as it had been the night before, and I saw that wonderful abbey rise up before me as I approached it. After several hours' walking, I reached the enormous mass of rock which supports the little town, dominated by the great church. Having climbed the steep and narrow street, I entered the most wonderful Gothic building that has ever been erected to God on earth, large as a town, and full of low rooms which seem buried beneath vaulted roofs, and of lofty galleries supported by delicate columns.

     I entered this gigantic granite jewel, which is as light in its effect as a bit of lace and is covered with towers, with slender belfries to which spiral staircases ascend. The flying buttresses raise strange heads that bristle with chimeras. with devils, with fantastic ani-mals, with monstrous flowers, are joined together by finely carved arches, to the blue sky by day, and to the black sky by night.

     When I had reached the summit. I said to the monk who accompanied me: "Father, how happy you must be here!" And he replied: "It is very windy, Monsieur"; and so we began to talk while watching the rising tide, which ran over the sand and covered it with a steel cuirass.

     And then the monk told me stories, all the old stories belonging to the place - legends, nothing but legends.

     One of them struck me forcibly. The country people, those belonging to the Mornet, declare that at night one can hear talking going on in the sand, and also that two goats bleat, one with a strong, the other with a weak voice. Incredulous people declare that it is nothing but the screaming of the sea birds, which occasionally resembles bleatings, and occasionally human lamentations; but belated fishermen swear that they have met an old shepherd, whose cloak covered head they can never see, wandering on the sand, between two tides, round the little town placed so far out of the world. They declare he is guiding and walking before a he-goat with a man's face and a she-goat with a woman's face, both with white hair, who talk incessantly, quarreling in a strange language, and then suddenly cease talking in order to bleat with all their might.

     "Do you believe it?" I asked the monk. "I scarcely know," he replied; and I continued: "If there are other beings besides ourselves on this earth, how comes it that we have not known it for so long a time, or why have you not seen them? How is it that I have not seen them?"

     He replied: "Do we see the hundred-thousandth part of what exists? Look here; there is the wind, which is the strongest force in nature. It knocks down men, and blows down buildings, uproots trees, raises the sea into mountains of water, destroys cliffs and casts great ships on to the breakers; it kills, it whistles, it sighs, it roars. But have you ever seen it, and can you see it? Yet it exists for all that."

     I was silent before this simple reasoning. That man was a philosopher, or perhaps a fool; I could not say which exactly, so I held my tongue. What he had said had often been in my own thoughts.

     July 3. I have slept badly; certainly there is some feverish influence here, for my coachman is suffering in the same way as I am. When I went back home yesterday, I noticed his singular paleness, and I asked him: "What is the matter with you, Jean?"

     "The matter is that I never get any rest, and my nights devour my days. Since your departure, Monsieur, there has been a spell over me."

     However, the other servants are all well, but I am very frightened of having another attack, myself.

     July 4. I am decidedly taken again; for my old nightmares have returned. Last night I felt somebody leaning on me who was sucking my life from between my lips with his mouth. Yes, he was sucking it out of my neck like a leech would have done. Then he got up, satiated, and I woke up, so beaten, crushed, and annihilated that I could not move. If this continues for a few days, I shall certainly go away again.

     July 5. Have I lost my reason? What has happened? What I saw last night is so strange that my head wanders when I think of it!

     As I do now every evening, I had locked my door; then, being thirsty, I drank half a glass of water, and I accidentally noticed that the water-bottle was full up to the cut-glass stopper.

     Then I went to bed and fell into one of my terrible sleeps, from which I was aroused in about two hours by a still more terrible shock.

     Picture to yourself a sleeping man who is being murdered, who wakes up with a knife in his chest, a gurgling in his throat, is covered with blood, can no longer breathe, is going to die and does not understand anything at all about it - there you have it.

     Having recovered my senses, I was thirsty again, so I lighted a candle and went to the table on which my water-bottle was. I lifted it up and tilted it over my glass, but nothing came out. It was empty! It was completely empty! At first I could not understand it at all; then suddenly I was seized by such a terrible feeling that I had to sit down, or rather fall into a chair! Then I sprang up with a bound to look about me; then I sat down again, overcome by astonishment and fear, in front of the transparent crystal bottle! I looked at it with fixed eyes, trying to solve the puzzle, and my hands trembled! Some body had drunk the water, but who? I? I without any doubt. It could surely only be I? In that case I was a somnambulist - was living, without knowing it, that double, mysterious life which makes us doubt whether there are not two beings in us - whether a strange, unknowable, and invisible being does not, during our moments of mental and physical torpor, animate the inert body, forcing it to a more willing obedience than it yields to ourselves.

     Oh! Who will understand my horrible agony? Who will understand the emotion of a man sound in mind, wide-awake, full of sense, who looks in horror at the disappearance of a little water while he was asleep, through the glass of a water-bottle! And I remained sitting until it was daylight, without venturing to go to bed again.

     July 6. I am going mad. Again all the contents of my water-bottle have been drunk during the night; or rather I have drunk it!

     But is it I? Is it I? Who could it be? Who? Oh! God! Am I going mad? Who will save me?

     July 10. I have just been through some surprising ordeals. Undoubtedly I must be mad! And yet!

     On July 6, before going to bed, I put some wine, milk, water, bread, and strawberries on my table. Somebody drank - I drank - all the water and a little of the milk, but neither the wine, nor the bread, nor the strawberries were touched.

     On the seventh of July I renewed the same experiment, with the same results, and on July 8 I left out the water and the milk and nothing was touched.

     Lastly, on July 9 I put only water and milk on my table, taking care to wrap up the bottles in white muslin and to tie down the stoppers. Then I rubbed my lips, my beard, and my hands with pencil lead, and went to bed.

     Deep slumber seized me, soon followed by a terrible awakening. I had not moved, and my sheets were not marked. I rushed to the table. The muslin round the bottles remained intact; I undid the string, trembling with fear. All the water had been drunk, and so had the milk! Ah! Great God! I must start for Paris immediately.

     July 12. Paris. I must have lost my head during the last few days! I must be the plaything of my enervated imagination, unless I am really a somnambulist, or I have been brought under the power of one of those influences - hypnotic suggestion, for example - which are known to exist, but have hitherto been inexplicable. In any case, my mental state bordered on madness, and twenty-four hours of Paris sufficed to restore me to my equilibrium.

     Yesterday after doing some business and paying some visits, which instilled fresh and invigorating mental air into me, I wound up my evening at the Theatre Francais. A drama by Alexander Dumas the Younger was being acted, and his brilliant and powerful play completed my cure. Certainly solitude is dangerous for active minds. We need men who can think and can talk, around us. When we are alone for a long time, we people space with phantoms.

     I returned along the boulevards to my hotel in excellent spirits. Amid the jostling of the crowd I thought, not without irony, of my terrors and surmises of the previous week, because I believed, yes, I believed, that an invisible being lived beneath my roof. How weak our mind is; how quickly it is terrified and unbalanced as soon as we are confronted with a small, incomprehensible fact. Instead of dismissing the problem with: "We do not understand because we cannot find the cause," we immediately imagine terrible mysteries and supernatural powers.

     July 14. Fete of the Republic. I walked through the streets, and the crackers and flags amused me like a child. Still, it is very foolish to make merry on a set date, by Government decree. People are like a flock of sheep, now steadily patient, now in ferocious revolt. Say to it: "Amuse yourself," and it amuses itself. Say to it: "Go and fight with your neighbor," and it goes and fights. Say to it: "Vote for the Emperor," and it votes for the Emperor; then say to it: "Vote for the Republic," and it votes for the Republic.

     Those who direct it are stupid, too; but instead of obeying men they obey principles, a course which can only be foolish, ineffective, and false, for the very reason that principles are ideas which are considered as certain and unchangeable, whereas in this world one is certain of nothing, since light is an illusion and noise is deception.

     July 16. I saw some things yesterday that troubled me very much. I was dining at my cousin's, Madame Sable, whose husband is colonel of the Seventy-sixth Chasseurs at Limoges. There were two young women there, one of whom had married a medical man, Dr. Parent, who devotes himself a great deal to nervous diseases and to the extraordinary manifestations which just now experiments in hypnotism and suggestion are producing.

     He related to us at some length the enormous results obtained by English scientists and the doctors of the medical school at Nancy, and the facts which he adduced appeared to me so strange, that I declared that I was altogether incredulous.

     "We are," he declared, "on the point of discovering one of the most important secrets of nature, I mean to say, one of its most important secrets on this earth, for assuredly there are some up in the stars, yonder, of a different kind of importance. Ever since man has thought, since he has been able to express and write down his thoughts, he has felt himself close to a mystery which is impenetrable to his coarse and imperfect senses, and he endeavors to supplement the feeble penetration of his organs by the efforts of his intellect. As long as that intellect remained in its elementary stage, this intercourse with invisible spirits assumed forms which were commonplace though terrifying. Thence sprang the popular belief in the supernatural, the legends of wandering spirits, of fairies, of gnomes, of ghosts, I might even say the conception of God, for our ideas of the Workman-Creator, from whatever religion they may have come down to us, are certainly the most mediocre, the stupidest, and the most unacceptable inventions that ever sprang from the frightened brain of any human creature. Nothing is truer than what Voltaire says: 'If God made man in His own image, man has certainly paid Him back again.'

     "But for rather more than a century, men seem to have had a presentiment of something new. Mesmer and some others have put us on an unexpected track, and within the last two or three years especially, we have arrived at results really surprising."

     My cousin, who is also very incredulous, smiled, and Dr. Parent said to her: "Would you like me to try and send you to sleep, Madame?"

     "Yes, certainly."

     She sat down in an easy-chair, and he began to look at her fixedly, as if to fascinate her. I suddenly felt myself somewhat discomposed; my heart beat rapidly and I had a choking feeling in my throat. I saw that Madame Sable's eyes were growing heavy, her mouth twitched, and her bosom heaved, and at the end of ten minutes she was asleep.

     "Go behind her," the doctor said to me; so I took a seat behind her. He put a visiting-card into her hands, and said to her: "This is a looking-glass; what do you see in it?"

     She replied: "I see my cousin."

     "What is he doing?"

     "He is twisting his mustache."

     "And now?"

     "He is taking a photograph out of his pocket."

     "Whose photograph is it?"

     "His own."

     That was true, for the photograph had been given me that same evening at the hotel.

     "What is his attitude in this portrait?"

     "He is standing up with his hat in his hand."

     She saw these things in that card, in that piece of white pasteboard, as if she had seen them in a looking-glass.

     The young women were frightened, and exclaimed: "That is quite enough! Quite, quite enough!"

     But the doctor said to her authoritatively: "You will get up at eight o'clock to-morrow morning; then you will go and call on your cousin at his hotel and ask him to lend you the five thousand francs which your husband asks of you, and which he will ask for when he sets out on his coming journey."

     Then he woke her up.

     On returning to my hotel, I thought over this curious seance and I was assailed by doubts, not as to my cousin's absolute and undoubted good faith, for I had known her as well as if she had been my own sister ever since she was a child, but as to a possible trick on the doctor's part. Had not he, perhaps, kept a glass hidden in his hand, which he showed to the young woman in her sleep at the same time as he did the card? Professional conjurers do things which are just as singular.

     However, I went to bed, and this morning, at about half past eight, I was awakened by my footman, who said to me: "Madame Sable has asked to see you immediately, Monsieur." I dressed hastily and went to her.

     She sat down in some agitation, with her eyes on the floor, and without raising her veil said to me: "My dear cousin, I am going to ask a great favor of you."

     "What is it, cousin?"

     "I do not like to tell you, and yet I must. I am in absolute want of five thousand francs."

     "What, you?"

     "Yes, I, or rather my husband, who has asked me to procure them for him."

     I was so stupefied that I hesitated to answer. I asked myself whether she had not really been making fun of me with Dr. Parent, if it were not merely a very well-acted farce which had been got up beforehand. On looking at her attentively, however, my doubts disappeared. She was trembling with grief, so painful was this step to her, and I was sure that her throat was full of sobs.

     I knew that she was very rich and so I continued: "What! Has not your husband five thousand francs at his disposal? Come, think. Are you sure that he commissioned you to ask me for them?"

     She hesitated for a few seconds, as if she were making a great effort to search her memory, and then she replied: "Yes - yes, I am quite sure of it."

     "He has written to you?"

     She hesitated again and reflected, and I guessed the torture of her thoughts. She did not know. She only knew that she was to borrow five thousand francs of me for her husband. So she told a lie.

     "Yes, he has written to me."

     "When, pray? You did not mention it to me yesterday."

     "I received his letter this morning."

     "Can you show it to me?"

     "No; no - no - it contained private matters, things too personal to ourselves. I burned it."

     "So your husband runs into debt?"

     She hesitated again, and then murmured: "I do not know."

     Thereupon I said bluntly: "I have not five thousand francs at my disposal at this moment, my dear cousin."

     She uttered a cry, as if she were in pair; and said: "Oh! oh! I beseech you, I beseech you to get them for me."

     She got excited and clasped her hands as if she were praying to me! I heard her voice change its tone; she wept and sobbed, harassed and dominated by the irresistible order that she had received.

     "Oh! oh! I beg you to - if you knew what I am suffering - I want them to-day."

     I had pity on her: "You shall have them by and by, I swear to you."

     "Oh! thank you! thank you! How kind you are."

     I continued: "Do you remember what took place at your house last night?"

     "Yes."

     "Do you remember that Dr. Parent sent you to sleep?"

     "Yes."

     "Oh! Very well then; he ordered you to come to me this morning to borrow five thousand francs, and at this moment you are obeying that suggestion."

     She considered for a few moments, and then replied: "But as it is my husband who wants them - "

     For a whole hour I tried to convince her, but could not succeed, and when she had gone I went to the doctor. He was just going out, and he listened to me with a smile, and said: "Do you believe now?"

     "Yes, I cannot help it."

     "Let us go to your cousin's."

     She was already resting on a couch, overcome with fatigue. The doctor felt her pulse, looked at her for some time with one hand raised toward her eyes, which she closed by degrees under the irresistible power of this magnetic influence. When she was asleep, he said:

     "Your husband does not require the five thousand francs any longer! You must, therefore, forget that you asked your cousin to lend them to you, and, if he speaks to you about it, you will not understand him."

     Then he woke her up, and I took out a pocket-book and said: "Here is what you asked me for this morning, my dear cousin." But she was so surprised, that I did not venture to persist; nevertheless, I tried to recall the circumstance to her, but she denied it vigorously, thought that I was making fun of her, and in the end, very nearly lost her temper.

     There! I have just come back, and I have not been able to eat any lunch, for this experiment has altogether upset me.

     July 19. Many people to whom I have told the adventure have laughed at me. I no longer know what to think. The wise man says: Perhaps?

     July 21. I dined at Bougival, and then I spent the evening at a boatmen's ball. Decidedly everything depends on place and surroundings. It would be the height of folly to believe in the supernatural on the Ile de la Grenouilliere. But on the top of Mont Saint-Michel or in India, we are terribly under the influence of our surroundings. I shall return home next week.

     July 30. I came back to my own house yesterday. Everything is going on well.

     August 2. Nothing fresh; it is splendid weather, and I spend my days in watching the Seine flow past.

     August 4. Quarrels among my servants. They declare that the glasses are broken in the cupboards at night. The footman accuses the cook, she accuses the needlewoman, and the latter accuses the other two. Who is the culprit? It would take a clever person to tell.

     August 6. This time, I am not mad. I have seen - I have seen - I have seen! - I can doubt no longer - I have seen it!

     I was walking at two o'clock among my rose-trees, in the full sunlight - in the walk bordered by autumn roses which are beginning to fall. As I stopped to look at a Geant de Bataille, which had three splendid blooms, I distinctly saw the stalk of one of the roses bend close to me, as if an invisible hand had bent it, and then break, as if that hand had picked it! Then the flower raised itself, following the curve which a hand would have described in carrying it toward a mouth, and remained suspended in the transparent air, alone and motionless, a terrible red spot, three yards from my eyes. In desperation I rushed at it to take it! I found nothing; it had disappeared. Then I was seized with furious rage against myself, for it is not wholesome for a reasonable and serious man to have such hallucinations.

     But was it a hallucination? I turned to look for the stalk, and I found it immediately under the bush, freshly broken, between the two other roses which remained on the branch. I returned home, then, with a much disturbed mind; for I am certain now, certain as I am of the alternation of day and night, that there exists close to me an invisible being who lives on milk and on water, who can touch objects, take them and change their places; who is, consequently, endowed with a material nature, although imperceptible to sense, and who lives as I do, under my roof -

     August 7. I slept tranquilly. He drank the water out of my decanter, but did not disturb my sleep.

     I ask myself whether I am mad. As I was walking just now in the sun by the riverside, doubts as to my own sanity arose in me; not vague doubts such as I have had hitherto, but precise and absolute doubts. I have seen mad people, and I have known some who were quite intelligent, lucid, even clear-sighted in every concern of life, except on one point. They could speak clearly, readily, profoundly on everything; till their thoughts were caught in the breakers of their delusions and went to pieces there, were dispersed and swamped in that furious and terrible sea of fogs and squalls which is called MADNESS.

     I certainly should think that I was mad, absolutely mad, if I were not conscious that I knew my state, if I could not fathom it and analyze it with the most complete lucidity. I should, in fact, be a reasonable man laboring under a hallucination. Some unknown disturbance must have been excited in my brain, one of those disturbances which physiologists of the present day try to note and to fix precisely, and that disturbance must have caused a profound gulf in my mind and in the order and logic of my ideas. Similar phenomena occur in dreams, and lead us through the most unlikely phantasmagoria, without causing us any surprise, because our verifying apparatus and our sense of control have gone to sleep, while our imaginative faculty wakes and works. Was it not possible that one of the imperceptible keys of the cerebral finger-board had been paralyzed in me? Some men lose the recollection of proper names, or of verbs, or of numbers, or merely of dates, in consequence of an accident. The localization of all the avenues of thought has been accomplished nowadays; what, then, would there be surprising in the fact that my faculty of controlling the unreality of certain hallucinations should be destroyed for the time being?

     I thought of all this as I walked by the side of the water. The sun was shining brightly on the river and made earth delightful, while it filled me with love for life, for the swallows, whose swift agility is always delightful in my eyes, for the plants by the riverside, whose rustling is a pleasure to my ears.

     By degrees, however, an inexplicable feeling of discomfort seized me. It seemed to me as if some unknown force were numbing and stopping me, were preventing me from going further and were calling me back. I felt that painful wish to return which comes on you when you have left a beloved invalid at home, and are seized by a presentiment that he is worse.

     I, therefore, returned despite of myself, feeling certain that I should find some bad news awaiting me, a letter or a telegram. There was nothing, however, and I was surprised and uneasy, more so than if I had had another fantastic vision.

     August 8. I spent a terrible evening, yesterday. He does not show himself any more, but I feel that He is near me, watching me, looking at me, penetrating me, dominating me, and more terrible to me when He hides himself thus than if He were to manifest his constant and i
