At the end of the school year, 1843, he took at the Lycée St. Louis two “Accessits,”[8] and one first prize in physics, and at the “_Concours Général_”[9] a sixth “Accessit” in physics. He was admitted fourth on the list to the Ecole Normale. He then wrote from Arbois to M. Barbet, telling him that on his half-holidays he would give some lessons at the school of the Impasse des Feuillantines as a small token of his gratitude for past kindness. “My dear Pasteur,” answered M. Barbet, “I accept with pleasure the offer you have made me to give to my school some of the leisure that you will have during your stay at the Ecole Normale. It will indeed be a means of frequent and intimate intercourse between us, in which we shall both find much advantage.” Pasteur was in such a hurry to enter the Ecole Normale that he arrived in Paris some days before the other students. He solicited permission to come in as another might have begged permission to come out. He was readily allowed to sleep in the empty dormitory. His first visit was to M. Barbet. The Thursday half-holiday, usually from one to seven, was now from one to eight. “There is nothing more simple,” he said, “than to come regularly at six o’clock on Thursdays and give the schoolboys a physical science class.” “I am very pleased,” wrote his father, “that you are giving lessons at M. Barbet’s. He has been so kind to us that I was anxious that you should show him some gratitude; be therefore always most obliging towards him. You should do so, not only for your own sake, but for others; it will encourage him to show the same kindness to other studious young men, whose future might depend upon it.”
