An agricultural enterprise requires: 1st, a suitable person; 2nd, capital; 3rd, an estate. - Albrecht Daniel Thaer

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.

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.

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.
