Oh! Who will understand my horrible agony? Who will understand the emotion of a man who is sound in mind, wide awake, full of sound sense, and who looks in horror at the remains of a little water that has disappeared while he was asleep, through the glass of a water-bottle! And I remained there 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. Decidedly I am 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, 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. Irresistible sleep seized me, which was 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 that I have been brought under the power of one of those influences which have been proved to exist, but which have hitherto been inexplicable, which are called suggestions. 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 play by Alexandre Dumas the Younger was being acted, and his active and powerful mind completed my cure. Certainly solitude is dangerous for active minds. We require 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 head is, and how quickly it is terrified and goes astray, as soon as we are struck by a small, incomprehensible fact.
