TWO:The domestic serenity of the realm was, however, greatly disturbed at this moment by Dean Swift, who seized on the occasion to avenge himself on the Whig Ministry for the defeat and punishment of his party, and especially of his particular friends and patrons, Oxford and Bolingbroke. There had long been a great deficiency of copper coin in Ireland. The Government undertook to remove this pressing want of so useful a medium, and they set about it in an honest and honourable manner as regarded the quality of the coin. Tenders were issued, and various offers received for the coining of farthings and halfpence to the value of a hundred and eight thousand pounds. The proposal of Mr. William Wood, an iron and copper founder, of Wolverhampton, was accepted; but the quality of the coin, both as to weight and fineness, was determined by the advice of Sir Isaac Newton, then Master of the Mint, and Wood was bound under heavy penalties to furnish it according to this stipulation. Every care was used by the Ministers and the Solicitor- and Attorney-General to insure the supply of a much better copper coinage than Ireland had ever possessed before.As soon as five or six thousand of his troops were landed, Buonaparte commenced his march on Alexandria. The Turks manned the walls, and resisted furiously, incensed at this invasion by a Power with which they were nominally at peace. But the walls were ruinous; the French forced their way over several breaches, and commenced an indiscriminate massacre. The place was abandoned to pillage for four hours. As the Mamelukes were hated by the Arabs and the Copts, and were the military mercenaries of the country, chiefly recruited from Georgia and Circassia, Buonaparte determined to destroy them. He considered that he should thus rid himself of the only formidable power in Egypt, and at the same time conciliate the Bedouins and Fellahs. On the 7th of July he set out on his march for Cairo with his whole force. He marched up the bank of the Nile, but at such a distance as to prevent the soldiers from getting any water to quench their burning thirst. It was all that Buonaparte could do to keep his troops in subordination. For fourteen days this melancholy march was continued, when they came at once in sight of the Pyramids, not far distant from Cairo, and of the army of the Mamelukes, drawn up across their way, headed by Murad Bey. This force consisted of five thousand cavalryMamelukes, mounted on the finest Arabian horses in the world, trained to obey the slightest touch of the rein, to advance, wheel, or fly with wonderful rapidity. The riders were all fine men, armed with sabres, pistols, and blunderbusses of the best English workmanship. They were deemed invincible and were ruthlessly cruel. They presented in appearance the finest body of cavalry in the world, the plumes of their turbans waving in the air, and their arms glittering in the sun. There were, moreover, twenty thousand infantry lying in a slightly-entrenched camp on their right;[467] but these were a mere rabblefellaheen, or, in other words, peasantry, brought from their fields, and armed with matchlocks. They had forty pieces of cannon to defend the camp, but these had no carriages, being mounted on clumsy wooden frames. Buonaparte drew up his army so as to keep out of gunshot of the camp, and to deal only with the cavalry first. He formed his troops into squares to resist the onslaught of the cavalry; and as he saw the Mamelukes come on, he called to his men, "From yonder Pyramids twenty centuries behold your actions!" The Mamelukes came thundering on like a whirlwind, and sending before them the most horrible yells. Murad Bey said he would cut up the French like gourds. One of the French squares was thrown into confusion, but it recovered itself, and the battle was instantly a scene of the most desperate fury. The Mamelukes fought like demons; but, finding that they could not break the French ranks, whilst they and their horses were mown down by musketry and artillery, in despair they flung their pistols at their foes, backed their horses up to them to break them by kicking, and finding all unavailing, fled. Such as were left wounded on the ground crept forward to cut at the legs of the French soldiers. Both cavalry and infantry then, by swimming their horses, or in boats, attempted to cross the Nile, but the greater part were drowned in the attempt. Murad Bey, with the residue of his Mamelukes, escaped into Upper Egypt.
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.
THREE:It is a singular fact, and by no means creditable to the "collective wisdom of the nation," that we have had no authentic enumeration of the English people till the beginning of the nineteenth century. The result, however, of the census of 1800 showed that the population of England had made progress throughout the whole of the preceding century, with the exception of the first ten years, when it seemed to have declined. Mr. Finlayson, the actuary, drew up a statement founded on the returns of births, marriages, and deaths, giving an estimate of the population at decennial periods, from which it appears that in the year 1700 it was 5,134,516, and in 1800 it was 9,187,176. Further, from the decennial census we gather that the population of Great Britain and Ireland, which in 1821 amounted to 21,193,458, was at the enumeration in 1831, 24,306,719; the percentage rate of increase during that interval being 14.68, or very nearly 1? per cent. per annum; and that at the enumeration in 1841 the numbers were 26,916,991, being an increase since 1831 of 2,610,272, or 10?74 per cent., which is very little beyond 1 per cent. per annum. Comparing 1841 with 1821, it appears that the increase in the twenty years was in England 33?20, or 1?66 per cent. per annum; Wales, 27?06, or 1?35; Scotland, 25?16, or 1?25; Ireland, 20?50, or 1?02; the United Kingdom, 27?06, or 1?35 per cent. per annum. For the purpose of comparison with the corresponding number of years in the nineteenth century, it may be stated that the increase during thirty years, from 1700 to 1800, is computed to have amounted to 1,959,590, or 27

THREE:[See larger version]There was an energetic debate in each House as the Bill passed through. It was opposed in the Peers by Lords Lansdowne, Holland, and Erskine, but was carried by ninety-three against twenty-seven. Ten peers entered a strong protest on the journals against the measure, denying the traitorous conspiracy or the extensive disaffection to the Government alleged, affirming that the execution of the ordinary laws would have been amply sufficient, and that Ministers were not entitled to indemnity for causeless arrests and long imprisonments which had taken place, for the Bill went to protect them in decidedly illegal acts. In the House of Commons the Bill was strongly opposed by Brougham, Tierney, Mr. Lambtonafterwards Lord Durhamand Sir Samuel Romilly. They condemned the conduct of Ministers in severe language, while the Bill was supported by Canning, by Mr. Lambafterwards Lord Melbourne, who generally went with the other sideby Sir William Garrow, and Sir Samuel Shepherd, Attorney-General.
