TO THE REVEREND JAMES MADISON.
Paris, August 13, 1787.
Dear Sir,—I have been long, very long, without answering your favor of March 27, 1786, and since that I have received those of December 28, and by Mrs. Oster. The reason of this has been that the genius of invention and improvement in Europe seems to be absolutely taking a nap. We have nothing to communicate to you but of the small kind, such as making the axletree turn with the wheel, which has been proposed here, adopted by some, and thought to be proved best by experiment, though theory has nothing to urge in its favor. A hydrostatic waistcoat is lately announced, which a person puts on either above or below his clothes in a minute, and fills with air by blowing with the mouth in twelve seconds. It is not yet shown, however, so I cannot tell you either the manner or matter of its construction. It may be useful when the loss of a vessel is foreseen. Herschell's discovery of two satellites to his planet, you have heard of ere this. He first saw them in January last. One revolves round its principal in about a week; the other in about a fortnight. I think your conjecture that the periodical variation of light in certain fixed stars proceeds from Maculæ, is more probable than that of Maupertius, who supposes those bodies may be flat, and more probable also than that which supposes the star to have an orbit of revolution so large as to vary sensibly its degree of light. The latter is rendered more difficult of belief from the shortness of the period of variation. I thank you for the shells you sent me. Their identity with marine shells and their vicinity to the sea, argue an identity of cause. But still the shells found in the mountains are very imperfectly accounted for. I have lately become acquainted with a memoire on a petrification mixed with shells by a Monsieur de La Sauvagere, giving an exact account of what Voltaire had erroneously stated in his questions Encyclopediques, article Coquilles, from whence I had transferred it into my notes. Having been lately at Tours, I had an opportunity of enquiring into de La Sauvagere's character, and the facts he states. The result was entirely in his and their favor. This fact is so curious, so circumstantially detailed, and yet so little like any known operation of nature, that it throws the mind under absolute suspense. The memoir is out of print. But my bookseller is now in search of it, and if he can find it I will put a copy of it into a box of books I shall send by the September packet, addressed to Mr. Wythe. In the same box I will put for you the Bibliotheque Physico-economique, for 1786, 1787, the connoissance des tems, Fourcroy's Chemistry, wherein all the later discoveries are digested, and a number of my notes on Virginia, of a copy of which you will be pleased to accept. It is a poor crayon, which yourself and the gentlemen which issue from your school must fill up. We are doubtful here whether we are to have peace or war. The movements of Prussia and England indicate war; the finances of England and France indicate peace. I think the two last will endeavor to accommodate the Dutch differences. Be pleased to present me respectfully to Mrs. Madison, and after repeating the recommendation of my nephew to you, I take the liberty of assuring you of that esteem with which I am, dear Sir, your friend and servant.
TO THE HONORABLE J. BLAIR.
Paris, August 13, 1787.
Dear Sir,—I received the letter with which you were pleased to honor me, by Mrs. Oster, and immediately waited on her with a tender of my services. She had, however, so far got her matters arranged as to be no longer in fear of any disagreeable measure, and is since gone to establish herself with her friends in Lorraine. I wish she may not there have alarms of a different nature. We have hitherto been in hopes that the desperate state of the finances of France and England would indispose those powers to war, and induce them, by an armed mediation, to quiet the affairs of Holland. The actual march, however, of the Prussian troops, the departure of the British squadron somewhere westwardly, and the preparations for a naval armament at Brest, and a land one in the neighborhood of the Netherlands, render war at present more expected than it has been. Still we look to the necessities of the two principal powers as promising efficacy to the negotiations not yet broken off. Though we shall be neutrals, and as such shall derive considerable pecuniary advantages, yet I think we shall lose in happiness and morals by being launched again into the ocean of speculation, led to overtrade ourselves, tempted to become sea-robbers under French colors, and to quit the pursuits of agriculture, the surest road to affluence and best preservative of morals. Perhaps, too, it may divert the attention of the States from those great political improvements, which the honorable body, of which you are a member, will, I hope, propose to them. What these may be, I know not, but I am sure they will be what they should be. My idea is that we should be made one nation in every case concerning foreign affairs, and separate ones in whatever is merely domestic; that the Federal government should be organized into Legislative, Executive and Judiciary, as are the State governments, and some peaceable means of enforcement devised for the Federal head over the States. But of all these things you are a better judge. I have delivered your message to Mr. Mazzei, who is still here. Be so good as to present me respectfully to Mrs. Blair, and to be assured yourself of the sentiments of esteem and respect with which I have the honor to be, dear Sir, your most obedient, and most humble servant.
TO JOSEPH JONES.
