Following this proposition into modern engineering examples, we find how practice has gradually conformed to what these properties in belts suggest. Wire and other ropes of small diameter, to avoid air friction, and allowed to droop in low curves to avoid too many supporting pulleys, are now in many cases employed for transmitting power through long distances, as at Schaffhausen, in Germany. This system has been very successfully applied in some cases for distributing power in large manufacturing establishments. Belts, among which are included all flexible bands, do not afford the same facilities for [49]taking off power at different points as shafts, but have advantages in transmitting power to portable machinery, when power is to be taken off at movable points, as in the case of portable travelling cranes, machines, and so on.
An energy continually advancing through successive gradations, and diminishing as it advancessuch, as we have seen, is the conception of existence offered by Plotinus. We have seen, also, how to explain the genesis of one principle from another without the aid of supernatural volition or of mechanical causation, he is compelled to press into the service every sort of relationship by which two objects can be connected, and to invest it with a dynamical significance which only the phenomena of matter and motion can possess. But what he chiefly relies on for guidance in this tortuous labyrinth of timeless evolution, is the old Greek principle that contraries are generated from one another. And with him, as with the earlier thinkers, all contraries reduce themselves, in the last analysis, to the four great antitheses of the One and the Many, Being and not-Being, the Same and the Other, Rest and Motion. It matters nothing that he should have followed Plato to the extent of co-ordinating five of these terms as supreme archetypal Ideas, immediately resulting from the self-consciousness of Nous, and themselves producing all other forms of existence. They are used, quite independently of that derivation, to explain the connexion of the various323 creative principles with one another. Nous is deduced from its first cause as Being from not-Being, as the Many from the One, as Difference from Identity, and as Motion from Rest.474 To explain the generation of Soul from Nous is a more difficult problem. The One had originally been defined as the antithetical cause of Nous, and therefore the latter could easily be accounted for by simply reversing the analytical process; whereas Nous had not been defined as the cause of Soul, but as the model whence her creative Ideas are derived. Soul, in fact, is not opposed to anything; she is the connecting link between sense and spirit. In this strait, Plotinus seems to think that the antithesis between Rest and Motion is the best fitted to express the nature of her descent from the higher principle; and on one occasion he illustrates the relation of his three divine substances to one another by the famous figure of a central point representing the One, a fixed circle round that point representing the Nous, and outside that, again, a revolving circle representing the Soul.475 Still, the different parts of the system are very awkwardly pieced together at this juncture; for the creative energy of the Nous has already been invoked to account for the Ideas or partial intelligences into which it spontaneously divides; and one does not understand how it can be simultaneously applied to the production of something that is not an Idea at all.Her reserve told me that I would not get much information here, and, finishing my beer, I asked:They crawled through and hid themselves in the black shrubs. A policeman came running up and surveyed the wreck thoughtfully. His lantern played all over it, he stooped down and rubbed at the dull frame-work vigorously.
ONE:A lot of artillery and a great number of soldiers were in the market-place ready to start. The commander sent one of his officers to us, who addressed me, examined my papers, and then said that I had surely met Belgian soldiers on the way. Of course I denied this emphatically.The discovery by the Germans of so-called dep?ts of Belgian rifles, each rifle labelled with the name of a citizen, was a gigantic "misunderstanding." Already before the Germans occupied the town the burgomaster had issued an order that all arms should be delivered. The inhabitants had obeyed, and the rifles were provided with a card so that each might be returned to the lawful owner after the war. This collection of arms has been used by the Germans as evidence of an organised revolt of the citizens.
ONE:"See anybody leave the house?" Prout asked."That's it. For the present we have to sit here in the passage with the kitchen door open and watch for the faint gleam of light in the courtyard. It is safe to have a light there because there are blank walls on either side. I think, I rather think, that I am going to astonish you presently."
TWO:Finally, it must constantly be borne in mind that what will be learned is no less a question of faculties than effort, and that the means of succeeding are closed to none who at the beginning form proper plans, and follow them persistently."Which identical notes must have been in the possession of the murdered man for many hours after you say they passed into your possession."
THREE:"I should like you to see Mamie first," said Hetty. She spoke coolly enough, but her heart was beating furiously. "She is not at all well tonight. Dr. Bruce has been here, and says she is not to be left alone. A mother's care----"The fitting or finishing department of engineering establishments is generally regarded as the main one.
