To avoid imperfection in the running spindles of lathes, or any lateral movement which might exist in the running bearings, there have been many attempts to construct lathes with still centres at both ends for the more accurate kinds of work. Such an arrangement would produce a true cylindrical rotation, but must at the same time involve mechanical complication to outweigh the object gained. It has besides been proved by practice that good fitting and good material for the bearings and spindles of lathes will insure all the accuracy which ordinary work demands.

"Looks like it!" said Balmayne. "You left here all right some time ago."We have now reached a point in history where the Greek intellect seems to be struck with a partial paralysis, continuing for a century and a half. During that period, its activitywhat there is of itis shown only in criticism and erudition. There is learning, there is research, there is acuteness, there is even good taste, but originality and eloquence are extinct. Is it a coincidence, or is it something more, that this interval of sterility should occur simultaneously with the most splendid period of Latin literature, and that the new birth of Greek culture should be followed by the decrepitude and death of the Latin muse? It is certain that in modern Europe, possessing as it does so many independent sources of vitality, the flowering-times of different countries rarely coincide; England and Spain, from the middle of the sixteenth to the middle of the seventeenth century, being the only instances that we can recall of two countries almost simultaneously reaching the highest point of their literary development. Possibly, during the great age of Latin literature, all the most aspiring Greeks found employment as tutors in Roman families; while the reading public of the West were too much absorbed by the masterpieces composed in their own language,166 or too elated with the consciousness of a new superiority, to encourage the rivalry of those from whom they had wrested not only poetical independence, but also, what till then had never been disputed with the Greeks, supreme dominion in the world of mind. It is, at any rate, significant that while Greek was the favourite language of Roman lovers in the time of Lucretius and again in the time of Juvenal, there are no allusions to its having been employed by them during the intermediate period.264 Be this as it may, from the fall of the Republic to the time of Trajan, philosophy, like poetry and eloquenceor at least all philosophy that was positive and practicalbecame domiciled in Rome, and received the stamp of the Roman character. How Stoicism was affected by the change has been pointed out in a former chapter. What we have now to study is chiefly the reaction of Rome on the Greek mind, and its bearing on the subsequent development of thought.To exert a powerful force acting through but a short distance, percussive devices are much more effective and simple than those acting by maintained or direct pressure. A hammer-head may give a blow equal to many tons by its momentum, and absorb the reactive force which is equal to the blow; but if an equal force was to be exerted by screws, levers, or hydraulic apparatus, we can easily see that an abutment would be required to withstand the reactive force, and that such an abutment would require a strength perhaps beyond what ingenuity could devise.

THREE:CHAPTER IIINor is it only the personality of Socrates that has been so variously conceived; his philosophy, so far as it can be separated from his life, has equally given occasion to conflicting interpretations, and it has even been denied that he had, properly speaking, any philosophy at all. These divergent presentations of his teaching, if teaching it can be called, begin with the two disciples to whom our knowledge of it is almost entirely due. There is, curiously enough, much the same inner discrepancy between Xenophons Memorabilia and those111 Platonic dialogues where Socrates is the principal spokesman, as that which distinguishes the Synoptic from the Johannine Gospels. The one gives us a report certainly authentic, but probably incomplete; the other account is, beyond all doubt, a highly idealised portraiture, but seems to contain some traits directly copied from the original, which may well have escaped a less philosophical observer than Plato. Aristotle also furnishes us with some scanty notices which are of use in deciding between the two rival versions, although we cannot be sure that he had access to any better sources of information than are open to ourselves. By variously combining and reasoning from these data modern critics have produced a third Socrates, who is often little more than the embodiment of their own favourite opinions.

  • FORE:There was everything that Hetty required in the dining-room. She crept softly down the marble staircase in her stockinged feet; down below in the hall a solitary point of flame in the electric corona made fitful shadows everywhere. There was one light also in the big, dark, dining-room, which was always left there, so that Hetty had no difficulty in finding a syphon of soda-water. She crept out into the hall again and paused.

Skill, in the sense employed here, consists not only in preparing plans and in various processes for converting and shaping material, but also in the general conduct of an establishment, including estimates, records, system, and so on, which will be noticed in their regular order. The amount of labour involved, and consequently the first cost of machinery, is in a large degree as the number of mechanical processes required, and the time consumed in each operation; to reduce the number of these processes or operations, shorten the time in which they may be performed, [27] and improve the quality of what is produced, is the business of the mechanical engineer. A careful study of shop operations or processes, including designing, draughting, moulding, forging, and fitting, is the secret of success in engineering practice, or in the management of manufactures. The advantages of an economical design, and the most carefully-prepared drawings, are easily neutralised and lost by careless or improper manipulation in the workshop; an incompetent manager may waste ten pounds in shop processes, while the commercial department of a work saves one pound by careful buying and selling.To the criticism and systematisation of common language and common opinion succeeded the more laborious criticism and systematisation of philosophical theories. Such an enormous amount of labour was demanded for the task of working up the materials amassed by Greek thought during the period of its creative originality, and accommodating them to the popular belief, that not much could be done in the way of adding to their extent. Nor was this all. Among the most valuable ideas of the earlier thinkers were those which stood in most striking opposition to the evidence of the senses. As such they were excluded from the system which had for its object the reorganisation of philosophy on the basis of general consent. Thus not only did thought tend to become stationary, but it even abandoned some of the ground which had been formerly won.The steam cranes of Mr Morrison, which resemble hydraulic cranes, except that steam instead of water is employed as a medium for transmitting force, combine all the advantages of hydraulic apparatus, except positive movement, and evade the loss of power that occurs in the use of water. The elasticity of the steam is found in practice to offer no obstacle to steady and accurate movement of a load, provided the mechanism is well constructed, while the loss of heat by radiation is but trifling.After driving through this scene of misery we158 entered Charleroi, and exactly at that moment one of the springs of my motor broke in two, which made the car useless. Charleroi seemed worse damaged than Namur. According to an official statement issued at the time, one hundred and sixty-five houses had been burned, among them many on the fine Boulevard Audent, the Saint Joseph Institute, the convent of the S?urs de Namur, and the adjacent ancient, miraculous little chapel of "Sainte Marie des Remparts."
