When I went to deliver my packet to Mr. Lyons, I was surprised by seeing in him a man as different as possible from my preconceived notion of a Jewish rabbi; I never should have guessed him to be either a rabbi, or a Jew. I expected to have seen a man nearly as old as Methuselah, with a reverend beard, dirty and shabby, and with a blue pocket handkerchief. Instead of which I saw a gay looking man, of middle age, with quick sparkling black eyes, and altogether a person of modern appearance, both in dress and address. I thought I must have made a mistake, and presented my packet with some hesitation, reading aloud the direction to Mr. Israel Lyons--“I am the man, sir,” said he; “our honest friend Jacob has described you so well, Mr. Harrington--_Mr. William Harrington Harrington_ (you perceive that I am well informed)--that I feel as if I had had the pleasure of being acquainted with you for some time. I am very much obliged by this visit; I should have done myself the honour to wait upon you, but I returned only yesterday from the country, and my necessary engagements do not leave as much time for my pleasures as I could wish.” I perceived by the tone of his address, that, though he was a Hebrew teacher, he was proud of showing himself to be a man of the world. I found him in the midst of his Hebrew scholars, and moreover with some of the best mathematicians, and some of the first literary men in Cambridge. I was awe-struck, and should have been utterly at a loss, had it not been for a print of Mendelssohn over the chimney-piece, which recalled to my mind the life of this great man; by the help of that I had happily some ideas in common with the learned Jew, and we; entered immediately into conversation, much to our mutual relief and delight. Dr. Johnson, in one of his letters, speaking of a first visit from a young gentleman who had been recommended to his acquaintance, says, that “the initiatory conversation of two strangers is seldom pleasing or instructive;” but I am sure that I was both pleased and instructed during this initiatory conversation, and Mr. Lyons did not appear to be oppressed or encumbered by my visit. I found by his conversation, that though he was the son of a great Hebrew grammarian, and himself a great Hebrew scholar, and though he had written a treatise on fluxions, and a work on botany, yet he was not a mere mathematician, a mere grammarian, or a mere botanist, nor yet a dull pedant. In despite of the assertion, that “----Hebrew roots are always found To flourish best on barren ground,” this Hebrew scholar was a man of a remarkably fertile genius. This visit determined my course, and decided me as to the society which I kept during the three happy and profitable years I afterwards spent at Cambridge.
