To Joseph Willard Paris, March 24, 1789
SIR,
-- I have been lately honored with your letter of September the 24th, 1788, accompanied by a diploma for a Doctorate of Laws, which the University of Harvard has been pleased to confer on me. Conscious how little I merit it, I am the more sensible of their goodness and indulgence to a stranger, who has had no means of serving or making himself known to them. I beg you to return them my grateful thanks, and to assure them that this notice from so eminent a seat of science, is very precious to me.
The most remarkable publications we have had in France, for a year or two past, are the following. `Les voyages d'Anacharsis par l'Abbe Barthelemi,' seven volumes, octavo. This is a very elegant digest of whatever is known of the Greeks; useless, indeed, to him who has read the original authors, but very proper for one who reads modern languages only. The works of the King of Prussia. The Berlin edition is in sixteen volumes, octavo. It is said to have been gutted at Berlin; and here it has been still more mangled. There are one or two other editions published abroad, which pretend to have rectified the maltreatment both of Berlin and Paris. Some time will be necessary to settle the public mind, as to the best edition.
Montignot has given us the original Greek, and a French translation of the seventh book of Potolemy's great work, under the title of `Etat des etoiles fixes au second siecle,' in quarto. He has given the designation of the same stars by Flamstead and Beyer, and their position in the year 1786. A very remarkable work is the `Mechanique Analytique,' of Le Grange, in quarto. He is allowed to be the greatest mathematician now living, and his personal worth is equal to his science. The object of his work is to reduce all the principles of mechanics to the single one of the equilibrium, and to give a simple formula applicable to them all. The subject is treated in the algebraic method, without diagrams to assist the conception. My present occupations not permitting me to read any thing which requires a long and undisturbed attention, I am not able to give you the character of this work from my own examination. It has been received with great approbation in Europe. In Italy, the works of Spallanzani on digestion and generation, are valuable. Though, perhaps, too minute, and therefore tedious, he has developed some useful truths, and his book is well worth attention; it is in four volumes, octavo. Clavigaro, an Italian also, who has resided thirty-six years in Mexico, has given us a history of that country, which certainly merits more respect than any other work on the same subject. He corrects many errors of Dr. Robertson; and though sound philosophy will disapprove many of his ideas, we must still consider it as an useful work, and assuredly the best we possess on the same subject. It is in four thin volumes, small quarto. De la Land has not yet published a fifth volume.
The chemical dispute about the conversion and reconversion of air and water, continues still undecided. Arguments and authorities are so balanced, that we may still safely believe, as our fathers did before us, that these principles are distinct. A schism of another kind, has taken place among the chemists. A particular set of them here, have undertaken to remodel all the terms of the science, and to give to every substance a new name, the composition, and especially the termination of which, shall define the relation in which it stands to other substances of the same family. But the science seems too much in its infancy as yet, for this reformation; because, in fact, the reformation of this year must be reformed again the next year, and so on, changing the names of substances as often as new experiments develope properties in them undiscovered before. The new nomenclature has, accordingly, been already proved to need numerous and important reformations. Probably it will not prevail. It is espoused by the minority only here, and by very few, indeed, of the foreign chemists. It is particularly rejected in England.
In the arts, I think two of our countrymen have presented the most important inventions. Mr. Paine, the author of Common Sense, has invented an iron bridge, which promises to be cheaper by a great deal than stone, and to admit of a much greater arch. He supposes it may be ventured for an arch of five hundred feet. He has obtained a patent for it in England, and is now executing the first experiment with an arch of between ninety and one hundred feet. Mr. Rumsey has also obtained a patent for his navigation by the force of steam, in England, and is soliciting a similar one here. His principal merit is in the improvement of the boiler, and, instead of the complicated machinery of oars and paddles, proposed by others, the substitution of so simple a thing as the reaction of a stream of water on his vessel. He is building a sea vessel at this time in England, and she will be ready for an experiment in May. He has suggested a great number of mechanical improvements in a variety of branches; and upon the whole, is the most original and the greatest mechanical genius I have ever seen. The return of la Peyrouse (whenever that shall happen) will probably add to our knowledge in Geography, Botany and Natural History. What a field have we at our doors to signalise ourselves in! The Botany of America is far from being exhausted, its Mineralogy is untouched, and its Natural History or Zoology, totally mistaken and misrepresented. As far as I have seen, there is not one single species of terrestrial birds common to Europe and America, and I question if there be a single species of quadrupeds. (Domestic animals are to be excepted.) It is for such institutions as that over which you preside so worthily, Sir, to do justice to our country, its productions and its genius. It is the work to which the young men, whom you are forming, should lay their hands. We have spent the prime of our lives in procuring them the precious blessing of liberty. Let them spend theirs in shewing that it is the great parent of science and of virtue; and that a nation will be great in both, always in proportion as it is free. Nobody wishes more warmly for the success of your good exhortations on this subject, than he who has the honor to be, with sentiments of great esteem and respect, Sir,
your most obedient humble servant,
