Tower of the temple
The creation of a public revenue, raised by the contributions of all classes of society, with a definite sum to be kept in reserve, thus dates from the reign of Philip Augustus. The annual income of the State at that time amounted to 36,000 marks, or 72,000 pounds' weight of silver--about sixteen or seventeen million francs of present currency. The treasury, which was kept in the great tower of the temple, was under the custody of seven bourgeois of Paris, and a king's clerk kept a register of receipts and disbursements. This treasury must have been well filled at the death of Philip Augustus, for that monarch's legacies were very considerable.

The Venice parachute (1617), after an engraving of the time
The attached engraving is the exact reproduction of the parachute that the author also defines in the following terms, certainly inspired by those of Leonardo da Vinci: With a square veil stretched out with four equal poles and having tied four ropes to the four quinces, a man without danger will be able to throw himself from the top of a tower or some other prominent place; because although, at the hour, there is no wind, the effort of he who falls will bring wind which will hold back the sail, lest it fall violently, but gradually descend. The man therefore must measure himself with the size of the sail.
The Spectroscope, an Instrument for Analysing Light
This pictorial diagram illustrates the principal of Spectrum Analysis, showing how sunlight is decomposed into its primary colours. What we call white light is composed of seven different colours. The diagram is relieved of all detail which would unduly obscure the simple process by which a ray of light is broken up by a prism into different wave-lengths. The spectrum rays have been greatly magnified.

The Bastille
The subterranean cells of the Bastille did not differ much from those of the Châtelet. There were several, the bottoms of which were formed like a sugar-loaf upside down, thus neither allowing the prisoner to stand up, nor even to adopt a tolerable position sitting or lying down. It was in these that King Louis XI., who seemed to have a partiality for filthy dungeons, placed the two young sons of the Duke de Nemours (beheaded in 1477), ordering, besides, that they should be taken out twice a week and beaten with birch rods, and, as a supreme measure of atrocity, he had one of their teeth extracted every three months. It was Louis XI., too, who, in 1476, ordered the famous iron cage, to be erected in one of the towers of the Bastille, in which Guillaume, Bishop of Verdun, was incarcerated for fourteen years.

Principle of the parachute, drawing by Leonardo da Vinci
If Leonardo da Vinci's aerial flight experiments do not seem to have been carried out on a large scale, it is perhaps not the same with the parachute, the use of which is much safer. The description of Leonardo da Vinci was reproduced later, not without a notable improvement in the mode of representation of the apparatus, in a collection of machines, due to Fauste Veranzio and published in Venice in 1617.

Hotel of chamber of accounts
Hotel of the Chamber of Accounts in the Courtyard of the Palace in Paris. From a Woodcut of the "Cosmographie Universelle" of Munster, in folio: Basle, 1552. Thanks to the peace concluded with Flanders, on which occasion that country paid into the hands of the sovereign thirty thousand florins in gold for arrears of taxes, and, above all, owing to the rules of economy and order, from which Philip V., surnamed the Long, never deviated, the attitude of France became completely altered. We find the King initiating reform by reducing the expenses of his household. He convened round his person a great council, which met monthly to examine and discuss matters of public interest; he allowed only one national treasury for the reception of the State revenues; he required the treasurers to make a half-yearly statement of their accounts, and a daily journal of receipts and disbursements; he forbad clerks of the treasury to make entries either of receipts or expenditure, however trifling, without the authority and supervision of accountants, whom he also compelled to assist at the checking of sums received or paid by the money-changers.

Great Châtelet
In 1032, a new magistrate was created, called the Provost of Paris, whose duty it was to give assistance to the bourgeois in arresting persons for debt. This functionary combined in his own person the financial and political chief of the capital, he was also the head of the nobility of the county, he was independent of the governor, and was placed above the bailiffs and seneschals. He was the senior of the urban magistracy and police, leader of the municipal troops, and, in a word, the prefect (præfectus urbis), as he was called under the Emperor Aurelian, or the first magistrate of Lutetia, as he was still called under Clotaire in 663. Assessors were associated with the provost, and together they formed a tribunal, which was afterwards known as the Châtelet, because they assembled in that fortress, the building of which is attributed to Julius Caesar.

Father Lana's aerial ship (1670)
Certainly Lana's project is impracticable: the learned Jesuit did not foresee that his empty copper balloons would be crushed by the external atmospheric pressure; but he nevertheless had a very clear idea and very remarkable for his time of the principle of aerial navigation by balloons lighter than the volume of air which they move. He ends his long chapter with some very curious considerations: I do not see any other difficulties that can be opposed to this idea, except one which seems to me more important than all the others, and that God will not allow this invention to be ever successfully applied in practice, in order to prevent the consequences which would result from it for the civil and political government of men. Indeed, who does not see that there is no State which would be insured against a stroke of surprise, because this ship would be heading in a straight line on one of its strongholds, and, landing there, could descend there soldiers.
Facsimile of Leonardo da Vinci's drawings on artificial wings
The examination of the original drawings of the great Italian artist is intersting. We reproduce by heliogravure a complete plate; it makes it possible to follow the thought which presided over its execution. We let Dr. Hureau de Villeneuve interpret it. We see in the second row on the right a small character quite similar to a demon or a genie, for he wears a flame on his head and, next to this flame, a Latin cross. His arms end with the fingers of a bat. The figure is not yet finished when Leonardo already recognizes its insufficiency and, guessing the little muscular action of the arms, thinks of using the force of the legs. So we see a little higher, in the same plank, a vigorous man placed on his stomach, his legs bent and about to launch a violent kick. The protruding muscles, traced by an anatomist's pencil, reveal the great painter in an unassuming drawing.

Divining rod
There are many great contentions between miners concerning the forked twig, for some say that it is of the greatest use in discovering veins, and others deny it. Some of those who manipulate and use the twig, first cut a fork from a hazel bush with a knife, for this bush they consider more efficacious than any other for revealing the veins, especially if the hazel bush grows above a vein. Others use a different kind of twig for each metal, when they are seeking to discover the veins, for they employ hazel twigs for veins of silver; ash twigs for copper; pitch pine for lead and especially tin, and rods made of iron and steel for gold. All alike grasp the forks of the twig with their hands, clenching their fists, it being necessary that the clenched fingers should be held toward the sky in order that the twig should be raised at that end where the two branches meet. Then they wander hither and thither at random through mountainous regions. It is said that the moment they place their feet on a vein the twig immediately turns and twists, and so by its action discloses the vein; when they move their feet again and go away from that spot the twig becomes once more immobile.

Comparative size of molecules
An atom is the smallest particle of a chemical element. Two or more atoms come together to form a molecule: thus molecules form the mass of matter. A molecule of water is made up of two atoms of hydrogen and one atom of oxygen. Molecules of different substances, therefore, are of different sizes according to the number and kind of the particular atoms of which they are composed. A starch molecule contains no less than 25,000 atoms. Molecules, of course, are invisible. The above diagram illustrates the comparative sizes of molecules.
