The Jewish police-officer, L. M., came and examined me in the strictest manner. I told him that I wished to enter into service as a family-tutor in Berlin, and that therefore the length of my stay could not be exactly determined. I appeared to him suspicious; he believed he had seen me here before, and evidently looked on me as a comet, which comes nearer to the earth the second time than the first, and so makes the danger more threating. But when he saw by me a _Milloth Higgayon_ or Hebrew Logic, drawn up by Maimonides, and annotated by Mendelssohn, he went into a perfect rage. "Yes! yes!" he exclaimed, "that's the sort of books for me!" and as he turned to me with a threatening look, "Pack," he said, "out of Berlin as quick as you can, if you don't wish to be led out with all the honours!" I trembled, and knew not what to do; but as I had learnt that there was a Polish Jew, a man of talent, residing in Berlin for the sake of study, and received with esteem in the best families, I paid him a visit. He received me as a countryman in a very friendly manner, asked about my home in Poland, and what had brought me to Berlin. When I told him in reply, that from my childhood I had discovered an inclination to the sciences, had already made myself acquainted with this and that Hebrew work which touches upon these, and now had come to Berlin in order to be _Maamik Bechochmah_ (to become absorbed in the sciences), he smiled at this quaint rabbinical phrase, but gave me his full approval; and after conversing with me for some time, he begged me to visit him often, which I very willingly promised to do, and went away rejoicing in spirit. The very next day I visited my Polish friend again, and found with him some young people belonging to a prominent Jewish family, who visited him often, and conversed with him on scientific subjects. They entered into conversation with me, found much amusement in my jargon, as well as in my simplicity and open-heartedness; in particular they laughed heartily at the phrase, _Maamik Bechochmah_, of which they had heard already. All this gave me courage, and they assured me that I should not find myself mistaken in the expectation of being able to be _Maamik Bechochmah_ in Berlin. And when I made known my fear about the above-mentioned police-officer, they made me pluck up courage by promising to obtain protection for me from their family, so that I might remain in Berlin as long as I chose.
