Herr A---- M---- also, a good honest fellow, and at that time a wealthy man, allowed me free access to his house. Here I found Locke in the German translation, and I was pleased with him at the first hasty glance, for I recognised him as the best of the modern philosophers, as a man who had no interest but the truth. Accordingly I proposed to the tutor of Herr A---- M----, that he should take lessons from me on this admirable work. At first he smiled at my simplicity in proposing, that I, who had scarcely got the length of seeing Locke, should give lessons to him whose native tongue was German, and who had been brought up in the sciences. He acted, however, as if he found nothing offensive in the matter, accepted my proposal, and fixed an hour for the lessons. I presented myself at the time appointed, and began the lessons; but as I could not read a word of German correctly, I told my pupil to read aloud paragraph by paragraph in the text, and that then I should give him an exposition of each. My pupil, who pretended to be in earnest, consented to this also, to carry on the joke; but how great was his astonishment when he found, that no joke was to be played in the matter, that in fact my expositions and remarks, though delivered in my own peculiar language, evinced a genuine philosophical spirit. It was still more amusing, when I became acquainted with the family of Widow Levi, and made the proposal to her son, the young Herr Samuel Levi,[53] who is still my Maecenas, that he should take lessons from me in the German language. The studious youth, incited by my reputation, was resolved to make a trial, and wished me to explain Adelung's _German Grammar_. I, who had never seen Adelung's Grammar, did not allow myself to be at all disconcerted on this account.[54] My pupil was obliged to read Adelung bit by bit, while I not only expounded it, but added glosses of my own. In particular I found a good deal to take exception to in Adelung's philosophical explanation of the parts of speech; and I drew up an explanation of my own, which I communicated to my intelligent pupil, by whom it is still preserved.
