She made all haste to intervene, but Sister Hyacinthe had turned more quickly and caught La Grivotte in her arms. A frightful fit of coughing, however, prostrated the unhappy creature upon the seat, and for five minutes she continued stifling, shaken by such an attack that her poor body seemed to be actually cracking and rending. Then a red thread oozed from between her lips, and at last she spat up blood by the throatful. "Good heavens! good heavens! it's coming on her again!" repeated Madame de Jonquiere in despair. "I had a fear of it; I was not at ease, seeing her looking so strange. Wait a moment; I will sit down beside her." But the Sister would not consent: "No, no, madame, sleep a little. I'll watch over her. You are not accustomed to it: you would end by making yourself ill as well." Then she settled herself beside La Grivotte, made her rest her head against her shoulder, and wiped the blood from her lips. The attack subsided, but weakness was coming back, so extreme that the wretched woman was scarcely able to stammer: "Oh, it is nothing, nothing at all; I am cured, I am cured, completely cured!" Pierre was thoroughly upset: This sudden, overwhelming relapse had sent an icy chill through the whole carriage. Many of the passengers raised themselves up and looked at La Grivotte with terror in their eyes. Then they dived down into their corners again, and nobody spoke, nobody stirred any further. Pierre, for his part, reflected on the curious medical aspect of this girl's case. Her strength had come back to her over yonder. She had displayed a ravenous appetite, she had walked long distances with a dancing gait, her face quite radiant the while; and now she had spat blood, her cough had broken out afresh, she again had the heavy ashen face of one in the last agony. Her ailment had returned to her with brutal force, victorious over everything. Was this, then, some special case of phthisis complicated by neurosis? Or was it some other malady, some unknown disease, quietly continuing its work in the midst of contradictory diagnosis? The sea of error and ignorance, the darkness amidst which human science is still struggling, again appeared to Pierre. And he once more saw Doctor Chassaigne shrugging his shoulders with disdain, whilst Doctor Bonamy, full of serenity, quietly continued his verification work, absolutely convinced that nobody would be able to prove to him the impossibility of his miracles any more than he himself could have proved their possibility. "Oh! I am not frightened," La Grivotte continued, stammering. "I am cured, completely cured; they all told me so, over yonder."
