t length the first examination — on differentials and integrals — drew near, but I continued in a vague state which precluded me from forming any clear idea of what was awaiting me. Every evening, after consorting with Zuchin and the rest, the thought would occur to me that there was something in my convictions which I must change — something wrong and mistaken; yet every morning the daylight would find me again satisfied to be “comme il faut,” and desirous of no change whatsoever.

Such was the frame of mind in which I attended for the first examination. I seated myself on the bench where the princes, counts, and barons always sat, and began talking to them in French, with the not unnatural result that I never gave another thought to the answers which I was shortly to return to questions in a subject of which I knew nothing.
