On May 21, her doctor, Dr. Flesschutt, wrote to Pasteur: “If the interest I take in the child were not sufficient to stimulate my efforts, the mother’s courage would keep up my hopes and double my ardent desire for a happy issue.” Cécile died on May 23 after a sudden relapse. Pasteur only arrived at Chambéry in time to take to Arbois the remains of the little girl, which were buried near those of his mother, of his two other daughters, Jeanne and Camille, and of his father, Joseph Pasteur. The little cemetery indeed represented a cup of sorrows for Pasteur. “Your father has returned from his sad journey to Arbois,” wrote Madame Pasteur from Chambéry to her son who was at school in Paris. “I did think of going back to you, but I could not leave your poor father to go back to Alais alone after this great sorrow.” Accompanied by her who was his greatest comfort, and who gave him some of her own courage, Pasteur came back to the Pont Gisquet and returned to his work. M. Duclaux in his turn joined the hard-working little party. At the beginning of June, Duruy, with the solicitude of a Minister who found time to be also a friend, wrote affectionately to Pasteur-- “You are leaving me quite in the dark, yet you know the interest I take in your work. Where are you? and what are you doing? Finding out something I feel certain....” Pasteur answered, “Monsieur le Ministre, I hasten to thank you for your kind reminder. My studies have been associated with sorrow; perhaps your charming little daughter, who used to play sometimes at M. Le Verrier’s, will remember Cécile Pasteur among other little girls of her age that she used to meet at the Observatoire. My dear child was coming with her mother to spend the Easter holidays with me at Alais, when, during a few days’ stay at Chambéry, she was seized with an attack of typhoid fever, to which she succumbed after two months of painful suffering. I was only able to be with her for a few days, being kept here by my work, and full of deceiving hopes for a happy issue from that terrible disease. “I am now wholly wrapped up in my studies, which alone take my thoughts from my deep sorrow. “Thanks to the facilities which you have put in my way, I have been able to collect a quantity of experimental observations, and I think I understand on many points this disease which has been ruining the South for fifteen or twenty years. I shall be able on my return to propose to the Commission of Sericiculture a practical means of fighting the evil and suppressing it in the course of a few years.
