“The art of agriculture is the realization of some ideal object. lie who practises it has received from others, without considering the reasons on which it is founded, the idea or rule by which he proceeds. The skilful practice of an art consists, therefore, in the adoption of new ideas, in the study of new rules, and in judging the fitness of their being carried into practice.”

“In the second year of my residence in Gottingen, I entered my name for a course of lectures on practical physics, against the advice of all my friends, but I have never regretted so doing, as there never has been, and probably never will be, a greater man at the university than Doctor Schroder, physician to the king, who gave, at that period, his celebrated lectures on practical physics. Schroder himself was astonished at the step I had taken; but when he perceived that I fully understood him, I became one of his favourite pupils; nor had I the advantage alone of receiving private lessons gratis, but he took me with him in most of his professional visits, where I had all the advantages of his great practice. Thus I caught a putrid fever which was then very prevalent; Schroeder attended me day and night, and giving up all hopes of my recovery, he observed to one of his friends, not thinking that I understood what he said, "The expansion of the sinews increases." "Then," answered I, in a quiet manner, "I shall die in four days, according to such and such a rule of Hippocrates: pray, prepare my father to receive the news of my death." However, immediately after, a sudden turn in the disorder taking place, I soon recovered; not so my memory, which I lost for a time, so that I had forgotten the names of my best friends; my nerves were so completely shaken, that I had no wish to recover. After my recovery, Professor Schroeder being himself attacked with the same fever, requested of his wife that no other physician than myself should attend him; but when he became light-headed, she called in all the physicians of Gottingen, and these gentlemen not agreeing in opinion respecting the treatment of the patient, this great and learned man fell a victim to ignorance and jealousy, April 21, 1772. I cannot think of this celebrated and good man without shedding tears of regret and gratitude.”

“I began to reconcile myself to my forlorn condition, but still I was not what I wished to be: the worst of all was, I had no friend; not a human being that understood me. I wrote daily to my friend Leisewitz; he resided in Hanover, and was just as unhappy as myself, except that he had some friends, and plenty of money. In this respect I was differently situated, and although in want of money to buy books, I was determined not to be any expense to my father. Some watches, snuff-boxes, and rings, presents I had received in Gottingen, soon found their way to the hands of Jews at half price. I was even, against my will, driven to the necessity of accepting small fees from mechanics and peasants. This cut me to the heart; but I could not help myself. The following circumstance, however, overcame me more than all: My father was a man of great knowledge and experience, but, like all old men, he remained faithful to the old method of practice. I visited many of his patients, and without telling me exactly what mode of treatment I was to pursue, he only observed, "You will act so and sohowever, I saw the patients had confidence in my father only, and not in me; they wished me to be his tool, and I therefore followed his mode of practice, and thus lost several of his patients, who could have been saved had I followed my own method.”

“When humus remains constantly damp, without, however, being covered with water, it forms a very unpleasant smelling acid, which is more particularly, characterized by the property which it possesses of colouring blue litmus paper into red. This circumstance has long been known, and it is the reason that land and meadows which are not properly drained, and which exhibit these phenomena, are called sour. We have carefully examined these facts, and have endeavoured to discover the peculiar constitution of this acid. At first, we were inclined to regard it as being of a distinct nature, and having carbon for its base; but we have since become convinced that it is generally composed of acetic acid, and occasionally contains a portion of the phosphoric. This latter always adheres so firmly to the humus that it cannot be separated from it either by boiling or washing. The liquid in which the humus is boiled certainly acquires a slight acid flavour, but the greater part of the acid remains attached to the humus.
This acid or sour humus it not at all of a fertilizing nature; on the contrary, it is prejudicial to vegetation* Where it is very strong and pervades the whole of the humus, the soil only produces reeds, rushes, sedge, and other useless, unpalatable plants; and whenever these abound, it may be inferred that the soil contains a great deal of sour or acid humus… There are various means of getting rid of this baneful property, and rendering the humus fertile. It is well known that with the aid of alkalies, ashes, lime, and marl, humus may be deprived of its acidity, and rendered easily soluble… Heaths do not thrive where this humus does not exist, and when they have established themselves in one particular spot, they suffer few other plants to appear. This humus may be changed by a dressing composed of marl, lime, or ammonia; and where this has been mixed with the soil, the heaths, &c., speedily perish.”

“The religious instruction I received of the Lutheran pastor Bode, preparatory to my confirmation, produced no effect upon my mind in favour of the truth of our divine religion, having studied all the works written against it with so much energy. I often insinuated to pastor Bode my doubts on religious matters, but either he did not or would not understand me; I was wavering between deism and atheism, so much so, that had it not been for the love towards my revered father, and the persuasions of Ferry, I should have avoided being present at the imposing and sacred ceremony of confirmation, which produced such an effect upon my young mind, that I prayed sincerely to God to give me faith, and had I not continued to read with Ferry and one Belzing so many blasphemous works, I should have returned to my former religious principles much sooner, as I did at a later period of my life.”

“After his death I did not attend any more lectures, although I paid for them. Schroeder was succeeded by Ernst Gottfried Baldinger, born in Gross Vargula, near Erfurt, 1738; and descended in a direct line, on his mother's side, from Doctor Martin Luther. He established a dispensary for poor patients, and gave medicine gratia, on condition of his being attended by about thirty pupils. Here it was that I first began to display the knowledge I had gained from my friend, the late Doctor Schroeder; and Baldinger, not seeing me attend his lectures, naturally supposing I was lazy and dull of comprehension, exclaimed, with astonishment, "What will become of this boy?" Whereupon, considering myself insulted by the Doctor, I wished to retire; when he embraced me, and said, good-humouredly, "No, no such a clever young fellow never came under my observation." From this time I became his best friend and daily visitor; I passed whole days and weeks in his valuable and extensive library, and almost in the constant society of his amiable, highly gifted, and accomplished wife; his confidence was so great, that he left the entire direction of his dispensary to me, and even entrusted me with the care of his own family when unwell. Having given up all connexion with my former friends, the students, I selected one Leisewitz, the author of "Julius de Tarent." We sympathised in each other's feelings, and became inseparable. His amiable qualities and inoffensive wit drew around us the best society; but, to our great regret, many of them belonged to a new school of freethinkers, whose principles we endeavoured, by the assistance of the pious Madame Baldinger, to eradicate from their minds; and thus it was thnt Providence brought me over again to the firm belief of the truth of our Divine religion.”

“By capital we understand everything that, from the special use by the individual, or from its being placed at the disposal of others, produces a revenue or rent. We do not inquire into its origin, or ask whether it has been acquired by inheritance or by labour.”

“The physicians in Celle were fifteen years behind in their practice; they had heard of a new style of practice, but regarded it as a mere chimera. When I ventured to say a word or two, they did not understand me: when I appealed to some great authority, they were ignorant of it: when I spoke from my own practical experience, they looked at me, from head to foot, and said sneeringly, "Well, well; experience will come in time." But when by chance I ventured to make some proposal, they turned round, and wondered where they should find room enough in the churchyards to bury my patients. The great applause with which my Dissertations had been received in all the learned journals, even in England as well as in France, gave me courage, hoping that this circumstance would make some impression on the mind of the public; but it was generally thought I had ill employed my time, and knew little or nothing. Being obliged to frequent society, I was so disgusted with the general tone and the topics of their conversation, that I was almost in despair; at last, some young ladies treated me with more attention.”

“I was very sickly and weak during the first years of my infancy, and was, as much as I can remember of myself, a very whimsical boy. Sometimes I learned with enthusiasm, and often found myself in such a kind of ecstasy, that I neither could see nor hear what passed around me. In these fits of thought I forgot playthings and playfellows; I was happy only in my own musings. I always preferred the company of little girls to boys. I was not ten years old when I presented them with some poetry and little verses, the effusions of my heated imagination; some of them fell into my hands in riper years, and after reading them over, I left off poetry altogether. I loved my first private teacher very much; I even can remember him now. My second teacher was a simpleton; he could never understand me, nor enter into my feelings. My antipathy to this man grew daily greater; I could not learn of him, nor could he teach me anything. At last, when in my thirteenth year, I got rid of him, and he being encumbered with debts, I gave him my saving-box when he left. Whether I did this for pity's sake, or joy to get rid of him, I did not know.”

“My father sent me, the same year, to school, but here I was not in my sphere; I hated the low and vulgar conduct of my school-fellows as much as the vulgar mode of correction of the masters. However, I selected some boys a little better educated for my daily companions, especially one of the name of Strauss, who unfortunately combined with his romantic ideas a great inclination to drink; we daily played truant, but nevertheless I applied myself in my private lessons with great eagerness and perseverance to the study of mathematics, history, &c., so that I contrived to ingratiate myself in the good opinion of my masters, who never missed me during the school hours, being always ready when called to my class. My best friend amongst the masters was a teacher of the French language, named Ferry) who professed secretly all the principles of freethinkers. He procured for me all the works of Voltaire, and other French freethinkers; and some time after, when I understood English, all the works of freethinkers of that nation. This was a pretty preparation for my confirmation, which was now at hand.”
