When she wrote to me in this strain, my heart was fit to break.  As a child, I was in the habit of asking her ten times over in the course of the day—­“Mother, have I been good?” The idea of a rupture between us was most cruel.  I accordingly resorted to various devices in order to prove to her that I was still the same tender son that I had been in the past.  In time the wound healed, and when she saw that I was as tender and loving towards her as ever, she readily agreed that there might be more than one way of being a priest, and that nothing was changed in me except the dress, which was the literal truth.

My ignorance of the world was thorough-paced.  I knew nothing except of literary matters, and as my only real knowledge was that which I gained at St. Sulpice, I have always been like a child in all worldly matters.  I did not therefore make any effort to render my material position as good as the circumstances admitted.  The one object of life seemed to me to be thought.  The educational profession being the one which comes nearest to the clerical one, I selected it almost without reflection.  It was hard, no doubt, after having reached the maximum of intellectual culture, and having held a post of some honour, to descend to the lowest rank.  I was better versed than any living Frenchman, with the exception of M. Le Hir, in the comparative theory of the Semitic languages, and my position was no better than that of an under-master; I was a savant, and I had not taken a degree.  But the inward contentment of my own conscience was enough for me.  I never felt a shadow of regret at the decision which I had come to in October, 1845.

I had my reward, moreover, the day after I entered the humble school in which I was to occupy for three years and a-half such a lowly position.  Among the pupils was one who, owing to his successes and rapid progress, held a place of his own in the school.  He was eighteen years old, and even at that early age the philosophical spirit, the concentrated ardour, the passionate love of truth, and the inventive sagacity which have since made his name celebrated were apparent to those who knew him.  I refer to M. Berthelot, whose room was next to mine.  From the day that we knew each other, we became fast friends.  Our eagerness to learn was equally great, and we had both had very different kinds of culture.  We accordingly threw all that we knew into the same seething cauldron which served to boil joints of very different kinds.  Berthelot taught me what was not to be learnt in the seminary, while I taught him theology and Hebrew.  Berthelot purchased a Hebrew Bible, which, I believe, is still in his library with its leaves uncut.  He did not get much beyond the Shevas, the counter attractions of the laboratory being too great.  Our mutual honesty and straightforwardness brought us closer together.  Berthelot introduced me to his father, one of those gifted doctors such as may be found in Paris.  The father was a Galilean
