"It was now, I thought, high time to think earnestly of getting into good practice as a physician. I followed, in order to effect this, my own method; I cared not for criticism; good luck attended me; I was successful in many cases given up by others as hopeless. My father watched me now closely, but let me have free sway; he felt great pleasure at my success, and would now and then say, "Well done, my boy;" but nevertheless entreated of me not to offend a certain great personage; which, however, I frankly confessed I had already done, not caring much about it, as it was my intention not to stay in Celle. I wanted a greater sphere of action. My father's weakness and infirmity increased daily, which prevented him from visiting his patients, and determined him to give up altogether his practice, and to retire from a profession in which, during many years, he had so nobly done his duty; he informed his patients of it, telling them that they were perfectly free and at liberty to take the advice of his son, or any other physician, thereby insinuating, that in their choice they must not suffer themselves to be influenced by their feelings of friendship and regard towards him. Almost all his patients honoured me with their confidence."

“Every person who seeks to practise agriculture with the full success which it admits—and that is the natural aim of every one who engages in it—must possess energy, activity, reflection, perseverance, and a knowledge of all the kindred and accessory sciences.”

“My father was a cool-tempered and unaffected man. Everyone who came in contact with him knew his straightforward way of acting, his scrupulous honesty; but few, very few, of his friends knew his noble and manly heart. Indifferent to praise and fame, as well as calumny, he was ever anxious to do good in silence; and it can be said of him, without fear of contradiction, that during his whole life he could never reproach himself with having been guilty of a bad or mean action.”

“In both the kinds of land we have been considering , we have supposed the humus to be mild, or exempt from acidity. J Sour or acid humus totally destroys the fertility of a soil; sometimes, however, the soil contains so very small a portion of acidity that its fertility is very slightly diminished, and only with regard to some few plants. Barley crops become more and more scanty in proportion as the acidity is increased; but oats do not appear to be at all affected by it. Rye grown on such land is peculiarly liable to rust, and is easily laid or lodged. The grains of all the oereals become larger, but contain less farina. Grass which grows on these spots is, both in species and taste, less agreeable, and less suitable for cattle, than any other, although it yields a very considerable produce in hay. In fact, in exact proportion with the increase of acidity, is the decrease of the value of the soil...”

“I continued for some time longer to ramble with Strauss and other school-fellows, to visit coffee-houses and billiard-rooms, but had a great antipathy to other debaucheries. The company of comedians of Mr. Seiler came just now to, performing comedies and tragedies. This was a new life for me; I became acquainted with each individual of this company; they all were fond of me; the beautiful Madame Koch gave me lessons in dancing, and I suddenly deserted all my former companions, neglecting them to such a degree, that one Mackphail, considering my conduct as an insult to the whole school, sent me a challenge, which ended in ray wounding him in the hand. My father loved me dearly, but did not much inquire into my conduct; he allowed me a great deal of money, but owing to my attachment to Ferry, whose salary was but small, I provided him with money, and having myself an extravagant taste for dress, I was often in great difficulties to pay my bills, of which my father was ignorant, till my creditors became troublesome, and my good father immediately discharged them, after giving me some kind admonition.”

“I was now in my sixteenth year, and for the first time it occurred to me that, although conversant with most of the modern languages, I did not understand a word of Latin, and thought the knowledge of this language indispensable to my future prospects in life. I spoke to Rector Steffens, and got permission of my father to leave school entirely, and devote my whole time to the study of Latin. In less than twelve months I was completely master of a language which is often the torment of boys from their sixth to their twentieth years, and still remain ignorant of it. Since then I have written several pamphlets in Latin, which were admired; and in my Discourses were generally delivered in that language. Doctor Taube, physician to the king, gave me lessons in natural history, botany, and anatomy; I bade farewell to philosophy and belles lettres, and began in earnest, and with great perseverance, to study physics; but still I was in bad odour amongst many of the learned, and it was said, when they heard of my progress, that henceforth they should not despair of making something of the most stupid of pupils.”
