From this day forth Pascal was as if possessed. The state of nervous exhaustion into which overwork and anxiety had thrown him left him an unresisting prey to this haunting fear of madness and death. All the morbid sensations which he felt, his excessive fatigue on rising, the buzzing in his ears, the flashes of light before his eyes, even his attacks of indigestion and his paroxysms of tears, were so many infallible symptoms of the near insanity with which he believed himself threatened. He had completely lost, in his own case, the keen power of diagnosis of the observant physician, and if he still continued to reason about it, it was only to confound and pervert symptoms, under the influence of the moral and physical depression into which he had fallen. He was no longer master of himself; he was mad, so to say, to convince himself hour by hour that he must become so.
All the days of this pale December were spent by him in going deeper and deeper into his malady. Every morning he tried to escape from the haunting subject, but he invariably ended by shutting himself in the study to take up again, in spite of himself, the tangled skein of the day before.
The long study which he had made of heredity, his important researches, his works, completed the poisoning of his peace, furnishing him with ever renewed causes of disquietude. To the question which he put to himself continually as to his own hereditary case, the documents were there to answer it by all possible combinations. They were so numerous that he lost himself among them now. If he had deceived himself, if he could not set himself apart, as a remarkable case of variation, should he place himself under the head of reversional heredity, passing over one, two, or even three generations? Or was his case rather a manifestation of larvated heredity, which would bring anew proof to the support of his theory of the germ plasm, or was it simply a singular case of hereditary resemblance, the sudden apparition of some unknown ancestor at the very decline of life?
From this moment he never rested, giving himself up completely to the investigation of his case, searching his notes, rereading his books. And he studied himself, watching the least of his sensations, to deduce from them the facts on which he might judge himself. On the days when his mind was most sluggish, or when he thought he experienced particular phenomena of vision, he inclined to a predominance of the original nervous lesion; while, if he felt that his limbs were affected, his feet heavy and painful, he imagined he was suffering the indirect influence of some ancestor come from outside. Everything became confused, until at last he could recognize himself no longer, in the midst of the imaginary troubles which agitated his disturbed organism. And every evening the conclusion was the same, the same knell sounded in his brain-heredity, appalling heredity, the fear of becoming mad.
In the early part of January Clotilde was an involuntary spectator of a scene which wrung her heart. She was sitting before one of the windows of the study, reading, concealed by the high back of her chair, when she saw Pascal, who had been shut up in his room since the day before, entering. He held open before his eyes with both hands a sheet of yellow paper, in which she recognized the genealogical tree. He was so completely absorbed, his gaze was so fixed, that she might have come forward without his observing her. He spread the tree upon the table, continuing to look at it for a long time, with the terrified expression of interrogation which had become habitual to him, which gradually changed to one of supplication, the tears coursing down his cheeks.
Why, great God! would not the tree answer him, and tell him what ancestor he resembled, in order that he might inscribe his case on his own leaf, beside the others? If he was to become mad, why did not the tree tell him so clearly, which would have calmed him, for he believed that his suffering came only from his uncertainty? Tears clouded his vision, yet still he looked, he exhausted himself in this longing to know, in which his reason must finally give way.
Clotilde hastily concealed herself as she saw him walk over to the press, which he opened wide. He seized the envelopes, threw them on the table, and searched among them feverishly. It was the scene of the terrible night of the storm that was beginning over again, the gallop of nightmares, the procession of phantoms, rising at his call from this heap of old papers. As they passed by, he addressed to each of them a question, an ardent prayer, demanding the origin of his malady, hoping for a word, a whisper which should set his doubts at rest. First, it was only an indistinct murmur, then came words and fragments of phrases.
"Is it you-is it you-is it you-oh, old mother, the mother of us all-who are to give me your madness? Is it you, inebriate uncle, old scoundrel of an uncle, whose drunkenness I am to pay for? Is it you, ataxic nephew, or you, mystic nephew, or yet you, idiot niece, who are to reveal to me the truth, showing me one of the forms of the lesion from which I suffer? Or is it rather you, second cousin, who hanged yourself; or you, second cousin, who committed murder; or you, second cousin, who died of rottenness, whose tragic ends announce to me mine -death in a cell, the horrible decomposition of being?"
And the gallop continued, they rose and passed by with the speed of the wind. The papers became animate, incarnate, they jostled one another, they trampled on one another, in a wild rush of suffering humanity.
"Ah, who will tell me, who will tell me, who will tell me?-Is it he who died mad? he who was carried off by phthisis? he who was killed by paralysis? she whose constitutional feebleness caused her to die in early youth?-Whose is the poison of which I am to die? What is it, hysteria, alcoholism, tuberculosis, scrofula? And what is it going to make of me, an ataxic or a madman? A madman. Who was it said a madman? They all say it-a madman, a madman, a madman!"
Sobs choked Pascal. He let his dejected head fall among the papers, he wept endlessly, shaken by shuddering sobs. And Clotilde, seized by a sort of awe, feeling the presence of the fate which rules over races, left the room softly, holding her breath; for she knew that it would mortify him exceedingly if he knew that she had been present.
Long periods of prostration followed. January was very cold. But the sky remained wonderfully clear, a brilliant sun shone in the limpid blue; and at La Souleiade, the windows of the study facing south formed a sort of hothouse, preserving there a delightfully mild temperature. They did not even light a fire, for the room was always filled with a flood of sunshine, in which the flies that had survived the winter flew about lazily. The only sound to be heard was the buzzing of their wings. It was a close and drowsy warmth, like a breath of spring that had lingered in the old house baked by the heat of summer.
