Paris, January 29, 1802.

Whenever the pen of an impartial writer shall trace the history of the French revolution, through all its accompanying vicissitudes, it will be seen that this country owed its salvation to the savans or men of science. The arts and sciences, which were revived by their zeal and courage, united with unceasing activity to pave the way to victories abroad, and repair mischiefs at home. Nor can it be denied, that every thing which genius, labour, and perseverance could create, in point of resources, was employed in such a manner that France was enabled, by land, to make head against almost all Europe, and supply her own wants, as long as the war lasted.

The savans who had effected such great things, for some time enjoyed unlimited influence. It was well known that to them the Republic was indebted for its safety and very existence. They availed themselves of this favourable moment for insuring to France that superiority of knowledge which had caused her to triumph over her enemies. Such was the origin of the

POLYTECHNIC SCHOOL.

This establishment had a triple object; namely, to form engineers for the different services; to spread in civil society enlightened men, and to excite talents which might promote the sciences. Nothing was neglected that could tend to the accomplishment of a destination so important.

It was, in fact, time to reorganize the instruction of corps destined for public services, the greater part of which were wholly deficient in this respect. Some of them, it is true, had particular schools; but instruction there was feeble and incomplete. That for military engineers at MÉzieres, the best conducted of all, and which admitted twenty pupils only, had suspended its exercises, in consequence of the revolution. Necessity had occasioned the formation of a provisionary school, where the pupils received rapidly the first notions of the attack and defence of places, after which they were sent to the armies.

Such institutions neither answered the exigencies of the State, nor conduced to its glory. Their weakness was, above all, likely to be felt by men habituated to general ideas, and whose minds were still more exalted, and views enlarged, by the revolution. Those men wished that the new School for Public Works should be worthy of the nation. Their plan was extensive in its object, but simple in its execution, and certain in its results.

The first law concerning the Central School for Public Works, since called the Polytechnic School, was made on the 20th of VentÔse year II. (10th of March 1794). From that moment, much zeal was manifested in making the necessary arrangements for its formation. On the report made to the National Convention respecting the measures taken on this subject, on the 7th of VendÉmiaire year III (28th of September 1794) a decree was passed, directing a competition to be opened for the admission of four hundred pupils into this school. The examination was appointed to take place in twenty-two of the principal towns. The candidates were to answer in arithmetic and the elements of algebra and geometry. Those admitted received the allowance of military officers for their travelling expenses to Paris. They were to have annually twelve hundred francs, and to remain in the school three years, after which they were to be called to the different Public Services, when they were judged capable of performing them; and priority was to depend on merit. These services were the duty of military engineers, naval engineers, or ship-builders, artillerists, both military and naval, engineers of bridges and highways, geographical engineers, and engineers of mines, and to them were added the service of the pupils of the school of aËrostation, which GUYTON MORVEAU had caused to be established at Meudon, for the purpose of forming the aËrostatic company destined for manoeuvring air-balloons, applied to the art of war, as was seen at Maubeuge, Fleurus, Aix-la-Chapelle, &c.

However, the conception of this project was far more easy than its execution. It was doing little to choose professors from among the first men of science in Europe, if their lessons were not fixed in the mind of the pupils. Being unable to communicate them to each pupil in private, they stood in need of agents who should transmit them to this numerous assemblage of youth, and be, as it were, the nerves of the body. To form these was the first object.

Among the young men who had presented themselves at the competition, twenty of the most distinguished were selected. Philosophical instruments and a chemical laboratory were provided for them, and they were unremittingly exercised in every part of the plan which it was resolved to execute. These pupils, the greater part of whom had come from the schools for Public Service, felt the insufficiency of the instruction which they had there received. Eager to learn, their mind became inflamed by the presence of the celebrated men who were incessantly with them. The days sufficed not for their zeal; and in three months they were capable of discharging the functions for which they were intended.

Nor was this all. At a time when opinion and power might change from one moment to another, much risk was incurred if a definitive form was not at once given to the Polytechnic School. The authors of this vast project had seen the revolution too near not to be sensible of that truth. But they wished first, by a trial made on a grand scale, to insure their method, class the pupils, and shew what might be expected from them. They therefore developed to them, in rapid lectures, the general plan of instruction.

This plan had been drawn up agreeably to the views of men the best informed, amongst whom MONGE must be particularly mentioned. He had been professor at MeziÈres, and had there given the first lessons of descriptive geometry, that science so useful to the engineer. The enumeration of the various parts of instruction was reduced to a table, printed by order of the Committee of Public Safety. It comprehends mathematics, analysis applied to descriptive geometry and to the mechanism of solids and fluids, stereotomy, drawing, civil architecture, fortification, general physics, chymistry, mineralogy, and their application to the arts.

In three months, the work of three years was explained. A real enthusiasm was excited in these youths on finding themselves occupied by the sublimest ideas which had employed the mind of man. Amidst the divisions and animosities of political party, it was an interesting sight, to behold four hundred young men, full of confidence and friendship, listening with profound attention to the lectures of the celebrated savans who had been spared by the guillotine.

The results of so great an experiment surpassed the most sanguine expectations. After this preliminary instruction, the pupils were divided into brigades, and education took the course it was intended should follow.

What particularly distinguishes this establishment, is that the pupils not only receive oral lessons, but they must give in written solutions, present drawings, models, or plans for the different parts, and themselves operate in the laboratories.

On the 1st of Germinal year III (22d of March 1795) the annual courses were commenced. They were then distributed for three years, but at this day they last two only. At the same time a decree was passed, regulating the number of professors, adjuncts, ushers, the holding of the meetings of the council of instruction and administration, the functions of the director, administrator, inspector of the studies, secretary of the council, librarian, keepers of the collection of drawings, models, &c.

Since that epoch, the Polytechnic School, often attacked, even in the discussions of the Legislative Body, has maintained its ground by the impression of the reputation of the men who act there as professors, of the depth of the knowledge which makes the object of their lessons, and of the youths of superior talent who issue from it every year. The law which after many adjournments, has fixed its existence is dated the 25th of Frimaire year VIII (16th of December 1799.)

The most important changes introduced, are the determination of the age to be received into this school, which is from sixteen to twenty, the reduction of the pupils to the number of three hundred, the rank which is given them of serjeant of artillery of the first class, their pay fixed on the same footing, together with a fund of assistance for those labouring under difficulties, the obligation to wear a uniform, the establishment of a council of improvement, composed of three members of the National Institute, of examiners, of a general-officer or superior agent of each of the branches of the Public Service, of the director, and four commissioners taken from the council of instruction.

This council assembles every year, inquires into the state of the school, proposes its views of amelioration, respecting every department, and makes a report to the government. One of its principal functions is to harmonise the instruction with that of the Schools of Engineers, Artillery, &c. into which the pupils enter after the final examination they undergo previously to their departure.

After this, to judge of the advantages of the Polytechnic School, it is sufficient to cast an eye on the printed reports, which present an account of the persons it furnishes to the different services, of those who have been taken from it for the expedition to Egypt, for the corps of aspirans de la marine or midshipmen, for entering into the line vith the rank of officers, or into the department of commissaries of war, (into which they are admitted after their examination if no places are vacant in the Schools for Public Service), of those who have been called on to profess the sciences in the central schools (Lyceums) of the departments, some to fill the first professors' chairs in Paris, such as at the CollÈge de France and the École Polytechnique, of those, in short, who have quitted this school to introduce into the manufactories the knowledge which they had acquired. The last-mentioned circumstance has always been a consideration for carrying the number of pupils beyond the presumable wants of the different Public Services.

You see that this is no more than a summary of what might be said and collected from the journals of the Polytechnic School, (which already form four volumes in 4to. independently of the classic works published by the professors), for giving a complete history of this interesting establishment, which attracts the notice of foreigners of all nations. BONAPARTE takes no small interest in the labours of the Polytechnic School, and has often said that it would be difficult to calculate the effects of the impulse which it has given towards the mathematical sciences, and of the aggregate of the knowledge imparted to the pupils.

The Polytechnic School, which is under the authority of the Minister of the Interior, occupies an extensive range of building, formerly known by the name of Le petit Palais Bourbon, contiguous to the Palais du Corps Legislatif. The different apartments contain every thing necessary for the elucidation of the arts and sciences here taught; but the pupils reside not at the school: they lodge and board with their friends, on the salary allowed them by the nation, and repair thither only for the prosecution of their studies.
