THREE:The spiteful little ripple of laughter was hushed as Leona Lalage returned. There was a flush on her face and a glitter in her eyes that Lawrence did not fail to notice. A little sheaf of banknotes fluttered in her hands.
THREE:The officer assured me that a new effort would be made soon, as they were commanded to take Pontisse and Lierce at any price, the seventh and ninth regiment of foot-artillery of Cologne being selected for the purpose.
THREE:No subject connected with mechanics has been more thoroughly investigated than that of gearing. Text-books are replete with every kind of information pertaining to wheels, at least so far as the subject can be made a mathematical one; and to judge from the amount of matter, formul?, and diagrams, relating to the teeth of wheels that an apprentice will meet with, he will no doubt be led to believe that the main object of modern engineering is to generate wheels. It must be admitted that the teeth of wheels and the proportions of wheels is a very important matter to understand, and should be studied with the greatest care; but it is equally important to know how to produce the teeth in metal after their configuration has been defined on paper; to understand the endurance of teeth under abrasive wear when made of wrought or cast iron, brass or steel; how patterns can be constructed from which correct wheels may be cast, and how the teeth of wheels can be cut [52]by machinery, and so on."Did Countess Lalage allude to it this morning?" he asked.
TWO:All existence, according to Plotinus, proceeds from the One, which he also calls God. But God does not create the world by a conscious exercise of power; for, as we have seen, every form of consciousness is excluded from his definition.319 Neither does it proceed from him by emanation, for this would imply a diminution of his substance.469 It is produced by an overflow of his infinite power.470 Our philosopher tries to explain and defend this rather unintelligible mode of derivation by the analogy of physical substances and their actions. Light is constantly coming from the sun without any loss to the luminary itself.471 And all things are, in like manner, constantly communicating their proper virtue to others while remaining unaltered themselves. Here we have a good example of the close connexion between science and abstract speculation. People often talk as if metaphysics was something beyond the reach of verification. But some metaphysical theories admit, at any rate, of disproof, in so far as they are founded on false physical theories. Had Plotinus known that neither the sun nor anything else in Nature can produce force out of nothing, he would, very probably, have hesitated to credit the One with such a power.A set of lathe tools should consist of all that are required for every variety of work performed, so that no time will be lost by waiting to prepare tools after they are wanted. An ordinary engine lathe, operating on common work not exceeding [126] twenty inches of diameter, will require from twenty-five to thirty-five tools, which will serve for every purpose if they are kept in order and in place. A workman may get along with ten tools or even less, but not to his own satisfaction, nor in a speedy way. Each tool should be properly tempered and ground, ready for use 'when put away;' if a tool is broken, it should at once be repaired, no matter when it is likely to be again used. A workman who has pride in his tools will always be supplied with as many as he requires, because it takes no computation to prove that fifty pounds of extra cast steel tools, as an investment, is but a small matter compared to the gain in manipulation by having them at hand.
