“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.”

“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.”

“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.”
