Passages from the Life of a Philosopher

In the course of this volume I have mentioned, under other heads, many agreeable circumstances, and many others remain unwritten. I shall now confine myself to two.

On one occasion when I was engaged in my workshop in arranging some machinery for experiments on a difficult part of the Analytical Engine, an intimate friend called, and I went into the library to see him. An unopened letter lying on the table, he asked whether I usually treated my letters in that way. I looked at the letter, which appeared to be a printed one. When my friend had left me, I opened it, and found that it professed to be from the Institute of France, announcing my nomination as a corresponding member of that distinguished body. On looking at the conclusion for the well-known signature of my friend Arago, I found another name which I could not read. I therefore concluded that some wag had played me a trick. I however doubted whether the joke was intended to hit me or the Academy of Sciences.
