TWO:CHAPTER XL. OF THE TREASURY.
THREE: The reader of this treatise will perceive that I have omitted all reference to a certain class of crime, which has deluged Europe with human blood; a crime which raised those fatal piles, where living human bodies served as food for the flames, and where the blind multitude sought a pleasant spectacle and a sweet harmony from the low dull groans, emitted by wretched sufferers from volumes of black smoke, the smoke of human limbs, whilst their bones and still palpitating entrails were scorched and consumed by the flames. But reasonable men will see that the place, the age, and the subject suffer me not to inquire into the nature of such a crime. It would be too long and remote from my subject to show, how a perfect uniformity of thought ought, contrary to the practice of many countries, to be a necessity in a State; how opinions, which only differ by the most subtle and imperceptible degrees, and are altogether beyond the reach of human intelligence, can[232] yet convulse society, when one of them is not legally authorised in preference to the others; and how the nature of opinions is such, that, whilst some become clearer by virtue of their conflict and opposition, (those that are true floating and surviving, but those that are false sinking to oblivion,) others again, with no inherent self-support, require to be clothed with authority and power. Too long would it be to prove, that howsoever hateful may seem the government of force over human minds, with no other triumphs to boast of but dissimulation and debasement, and howsoever contrary it may seem to the spirit of gentleness and fraternity, commanded alike by reason and the authority we most venerate, it is yet necessary and indispensable. All this should be taken as clearly proved and conformable to the true interests of humanity, if there be anyone who, with recognised authority, acts accordingly. I speak only of crimes that spring from the nature of humanity and the social compact; not of sins, of which even the temporal punishments should be regulated by other principles than those of a narrow philosophy.Count Pietro Verri was the son of Gabriel, who was distinguished alike for his legal knowledge and high position in Milan. At the house of Pietro, Beccaria and the other friends used to meet for the discussion and study of political and social questions. Alessandro, the younger brother of Pietro, held the office of Protector of Prisoners, an office which consisted in visiting the prisons, listening to the grievances of the inmates, and discovering, if possible, reasons for their defence or for mercy. The distressing sights he[10] was witness of in this capacity are said to have had the most marked effect upon him; and there is no doubt that this fact caused the attention of the friends to be so much directed to the state of the penal laws. It is believed to have been at the instigation of the two brothers that Beccaria undertook the work which was destined to make his name so famous.
THREE: From this necessity of the favour of other people arose private duels, which sprang up precisely in an anarchical state of the laws. It is said they were unknown to antiquity, perhaps because the ancients did not meet suspiciously armed in the temples, the theatres, or with friends; perhaps because the duel was an ordinary and common sight, presented to the people by gladiators, who were slaves or low people, and freemen disdained to be thought and called private gladiators. In vain has it been sought to extirpate the custom by edicts of death against any man accepting a challenge, for it is founded on that which some men fear more than death; since without the favour of his fellows the man of honour foresees himself exposed either to become a merely solitary being, a condition insufferable to a sociable man, or to become the butt of insults and disgrace which, from their constant operation, prevail over the fear of punishment. Why is it that the lower orders do not for the most part fight duels like the great? Not only because they are disarmed, but because the need of the favour of others is less general among the people[213] than among those who, in higher ranks, regard themselves with greater suspicion and jealousy.
A hydrocyclone (liquid cyclone) injects treatment solution into stationary equipment to perform separation, classification, and concentration, and is an innovative separator with a very simple structure and no drive unit.
Structure of a hydrocyclone (liquid cyclone)
A suspension containing fine particles of several micrometers or more is supplied to a cylindrical container circumferentially at high speed. And as a result it starts to rotate and a centrifugal force is generated. At this time a gravitational acceleration of several tens of thousands of G is generated in the circumferential direction, and thus leading to fast sedimentation and concentration of the fine particles. The separated concentration can be freely selected by changing the supply rate (supply pressure and flow rate) and the flow ratio of the outlet. Our hydrocyclone (liquid cyclone) was designed and manufactured to classify and concentrate fine particles, and so has a small element.
