In science, the mass of the people are two centuries behind ours; their literati, half a dozen years before us. Books, really good, acquire just reputation in that time, and so become known to us, and communicate to us all their advances in knowledge. Is not this delay compensated, by our being placed out of the reach of that swarm of nonsensical publications which issues daily from a thousand presses, and perishes almost in issuing? With respect to what are termed polite manners, without sacrificing too much the sincerity of language, I would wish my countrymen to adopt just so much of European politeness, as to be ready to make all those little sacrifices of self, which really render European manners amiable, and relieve society from the disagreeable scenes to which rudeness often subjects it. Here, it seems that a man might pass a life without encountering a single rudeness. In the pleasures of the table, they are far before us, because, with good taste they unite temperance. They do not terminate the most sociable meals by transforming themselves into brutes. I have never yet seen a man drunk in France, even among the lowest of the people. Were I to proceed to tell you how much I enjoy their architecture, sculpture, painting, music, I should want words. It is in these arts they shine. The last of them, particularly, is an enjoyment, the deprivation of which with us, cannot be calculated. I am almost ready to say, it is the only thing which from my heart I envy them, and which, in spite of all the authority of the Decalogue, I do covet. But I am running on in an estimate of things infinitely better known to you than to me, and which will only serve to convince you, that I have brought with me all the prejudices of country, habit, and age. But whatever I may allow to be charged to me as prejudice, in every other instance, I have one sentiment at least, founded on reality: it is that of the perfect esteem which your merit and that of Mrs. Bellini have produced, and which will forever enable me to assure you of the sincere regard with which I am, dear Sir, your friend and servant.
TO JAMES MADISON, OF WILLIAM AND MARY COLLEGE.
Paris, October 2, 1785.
Dear Sir,—I have duly received your favor of April the 10th, by Mr. Mazzei. You therein speak of a new method of raising water by steam, which you suppose will come into general use. I know of no new method of that kind, and suppose (as you say the account you have received of it is very imperfect) that some person has represented to you, as new, a fire engine erected at Paris, and which supplies the greater part of the town with water. But this is nothing more than the fire engine you have seen described in the books of hydraulics, and particularly in the Dictionary of Arts and Sciences, published in 8vo, by Owen, the idea of which was first taken from Papin's Digester. It would have been better called the steam engine. The force of the steam of water, you know, is immense. In this engine, it is made to exert itself towards the working of pumps. That of Paris is, I believe, the largest known, raising four hundred thousand cubic feet (French) of water, in twenty-four hours; or rather, I should have said, those of Paris, for there are two under one roof, each raising that quantity.
The Abbé Rochon not living at Paris, I have not had an opportunity of seeing him, and of asking him the questions you desire, relative to the crystal of which I wrote you. I shall avail myself of the earliest opportunity I can, of doing it. I shall cheerfully execute your commands as to the Encyclopedie, when I receive them. The price will be only thirty guineas. About half the work is out. The volumes of your Buffon which are spoiled, can be replaced here.
I expect that this letter will be carried by the Mr. Fitzhughs, in a ship from Havre to Portsmouth. I have therefore sent to Havre some books which I expected would be acceptable to you. These are the Bibliothéque Physico-œconomique, which will give you most of the late improvements in the Arts; the Connoissance des Tems for 1786 and 1787, which is as late as they are published; and some pieces on air and fire, wherein you will find all the discoveries hitherto made on these subjects. These books are made into a packet, with your address on them, and are put into a trunk, wherein is a small packet for Mr. Wythe, another for Mr. Page, and a parcel of books, without direction, for Peter Carr. I have taken the liberty of directing the trunk to you, as the surest means of its getting safe. I pay the freight of it here, so that there will be no new demands, but for the transportation from the ship's side to Williamsburg, which I will pray you to pay; and as much the greatest part is for my nephew, I will take care to repay it to you.
In the last volume of the Connoissance des Tems, you will find the tables for the planet Herschel. It is a curious circumstance, that this planet was seen thirty years ago by Mayer, and supposed by him to be a fixed star. He accordingly determined a place for it, in his catalogue of the zodiacal stars, making it the 964th of that catalogue. Bode, of Berlin, observed in 1781 that this star was missing. Subsequent calculations of the motion of the planet Herschel, show that it must have been, at the time of Mayer's observation, where he had placed his 964th star.
Herschel has pushed his discoveries of double stars, now, to upwards of nine hundred, being twice the number of those communicated in the Philosophical Transactions. You have probably seen, that a Mr. Pigott had discovered periodical variations of light in the star Algol. He has observed the same in the η of Antinous, and makes the period of variation seven days, four hours, and thirty minutes, the duration of the increase sixty-three hours, and of the decrease thirty-six hours. What are we to conclude from this? That there are suns which have their orbits of revolution too? But this would suppose a wonderful harmony in their planets, and present a new scene, where the attracting powers should be without, and not within the orbit. The motion of our sun would be a miniature of this. But this must be left to you astronomers.
I went some time ago to see a machine which offers something new. A man had applied to a light boat a very large screw, the thread of which was a thin plate, two feet broad, applied by its edge spirally around a small axis. It somewhat resembled a bottle brush, if you will suppose the hairs of the bottle brush joining together, and forming a spiral plane. This, turned on its axis in the air, carried the vessel across the Seine. It is, in fact, a screw which takes hold of the air and draws itself along by it; losing, indeed, much of its effort by the yielding nature of the body it lays hold of to pull itself on by. I think it may be applied in the water with much greater effect, and to very useful purposes. Perhaps it may be used also for the balloon.
