TWO:In 1710 was established the Academy of Ancient Music, the object of which was to promote the study of vocal and instrumental harmony. Drs. Pepusch, Greene, and other celebrated musicians were amongst its founders. They collected a very valuable musical library, and gave annual concerts till 1793, when more fashionable ones attracted the public, and the society was dissolved. In 1741 was established the Madrigal Society, the founder of which was John Immyns, an attorney. It embraced men of the working classes, and held meetings on Wednesday evenings for the singing of madrigals, glees, catches, etc. Immyns sometimes read them a lecture on a musical subject, and the society gradually grew rich. The composers of such pieces at this period were such men as Purcell, Eccles, Playford, Leveridge, Carey, Haydn, Arne, etc. Public gardens became very much the fashion, and in these, at first, oratorios, choruses, and grand musical pieces were performed, but, by degrees, gave way to songs and catches.[157] Vauxhall, originally called Spring Garden, established before the Revolution, became all through this period the fashionable resort of the aristocracy, and to this was added Ranelagh, near Chelsea College, a vast rotunda, to which crowds used to flock from the upper classes on Monday, Wednesday, and Friday evenings, to hear the music and singing. These performances spread greatly the taste for music, and probably excited the alarm of the puritanically religious, for there arose a loud outcry against using music in churches, as something vain and unhallowed. Amongst the best publications on the science of music during this period were Dr. Holder's "Treatise on the Natural Grounds and Principles of Harmony," 1694; Malcolm's "Treatise on Music, Speculative, Practical, and Historical," 1721; Dr. Pepusch's "Treatise on Harmony," 1731; Dr. Smith's "Harmonics; or, the Philosophy of Musical Sounds;" Avison's "Essay on Musical Expression," 1752. Avison also published twenty-six concertos for a band, which were much admired.The South Sea Company had immediately on the passing of the Bill proposed a subscription of one million, and this was so eagerly seized on that, instead of one, two millions were subscribed. To stimulate this already too feverish spirit in the public, the Company adopted the most false and unjustifiable means. They had eight millions and a half to pay over to Government as a douceur for granting them the management of the Funds; and, therefore, to bring this in rapidly, they propagated the most lying rumours. It was industriously circulated that Lord Stanhope had received overtures at Paris to exchange Gibraltar and Port Mahon for invaluable gold lands in Peru! The South Sea trade was vaunted as a source of boundless wealth in itself. In August the stock had risen from the one hundred and thirty of the last winter to one thousand! Men sold houses and land to become shareholders; merchants of eminence neglected their affairs and crippled their resources to reap imaginary profits. The Company flattered the delusion to the utmost. They opened a third, and even a fourth subscription, larger than the former, and passed a resolution that from next Christmas their yearly dividend should not be less than fifty per cent.! In labouring to increase the public delusion they seem to have caught the contagion themselves, for they began to act, not like men who were blowing a bubble which they knew must speedily burst, but like persons who had mounted permanently into the very highest seat of prosperous power. They assumed the most arrogant and overbearing manner, even towards men of the highest station and influence. "We have made them kings," said a member of Parliament, "and they deal with everybody as such."

Hydrocyclone (liquid cyclone)02

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.

It seems to us that such distinctions are out of relation to the historical order in which the different systems of Greek philosophy were evolved. It is not in the substance of their teaching, but in their diminished power of original speculation, that the thinkers who came after Aristotle offer the strongest contrast to their predecessors. In so far as they are exclusively practical and subjective, they follow the Humanists and Socrates. In so far as they combine Socratic tendencies with physical studies, they imitate the method of Plato and Aristotle. Their cosmopolitan naturalism is inherited from the Cynics in the first instance, more remotely from the physiocratic Sophists, and, perhaps, in the last resort, from Heracleitus. Their religion is traceable either to Pythagoras, to Socrates, or to Plato. Their scepticism is only a little more developed than that of Protagoras and the Cyrenaics. But if we seek for some one principle held in common by all these later schools, and held by none of the earlier schools, we shall seek for it in vain. The imitative systems are separated from one another by the same fundamental differences as those which divide the original systems. Now, in both periods, the deepest of all differences is that which divides the spiritualists from the materialists. In both periods, also, it is materialism that comes first. And in both, the transition from one doctrine to the other is marked by the exclusive prominence given to subjective, practical, sceptical, or theological interests in philosophy; by the enthusiastic culture of rhetoric in general education; and by a strong religious reaction in the upper ranks of society.
