The word " economy" has latterly been used in various senses; the Germans give it a very indefinite signification.
Judging from its etymology and original signification, the Greeks seem to have understood by it the establishment and direction of the menage, or domestic arrangements.
Xenophon, in his work on economy, treats of domestic management, the reciprocal duties of the members of a family and of those who compose the household; and only incidentally mentions agriculture as having relation to domestic affairs. This word is never applied to agriculture by Xenophon, nor, indeed, by any Greek author; they distinguish it by the terms, georgic geoponic.
The Romans give a very extensive and indefinite signification to the word "economy." They understand by it, the best method of attaining the aim and end of some particular thing; or the disposition, plan, and division of some particular work. Thus, Cicero speaks of oeconomia causae, oeconomia orationis; and by this he means the direction of a law process, the arrangement of an harangue. Several German authors use it in this sense when they speak of the oekonomie eines schauspiels, or eines gedichtes, the economy of a play or poem. Authors of other nations have adopted all the significations which the Romans have attached to this word, and understand by it the relation of the various parts of any particular thing to each other and to the whole—that which we are accustomed to term the organization. The word "economy" only acquires a real sense when applied to some particular subject: thus, we hear of "the economy of nature," "the animal economy," and " the economy of the state" spoken of. It is also applied to some particular branch of science or industry; but, in the latter case, the nature of the economy ought to be pointed out, if it is not indicated by the nature of the subject.
Arriving in Berlin, I found myself in my element, and began to breathe freely. Jerusalem and Lessing had given us letters of introduction to the greatest men in Berlin; but they knew us already, Leisewitz as author of "Julius Von Tarent," and myself as author of my Dissertation. We had daily the choice of the first society; covers were laid for us in the first families daily, for dinner as well as supper. Von Zetlitz sent a general invitation that covers were laid for us every day during our stay in Berlin. Most of the time we could spare was divided between physicians and philosophers, of which the latter had the greater share. Spalding, Mendelsohn, Eberhard, Engel, Nicolai, Reichard, and Madame Bamberger, daughter of Doctor Sack, Bishop of Berlin, honoured us with their most sincere friendship. The latter, a highly gifted and accomplished lady, possessed the rare art of spreading over the most abstract hypothesis and theorem the brightest and most charming light; Jerusalem, the father of the ill-fated Werther (see the "Sorrows of Werther," by Goethe), used to send her his works to correct, and she alone was able to console and comfort him, when he was informed of the death of his beloved son. This amiable lady assumes in common life the character of a plain woman, and when at court, as friend of the Queen and the Princess Amalie, she won all hearts by her truly noble man ners and unconstrained courtesy: at court beloved, she was admired, nay, adored in the philosophical clubs. But do not think that here alone we spent all our time; Madame Bamberger knew how to blend study with amusement; she issued frequently cards of invitation to select parties, for suppers and balls, and her house was the point of union of all that was learned, beautiful, and amiable. Thus Berlin became my Paradise. I had the most tempting offers from the Minister of State to stay here; but the illness of my father obliged me, after a stay of three months, to return home. I visited Lessing on my journey back; stayed two days, which were the most interesting of all days I ever remember.
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.
