In the remarks upon steam-engines it was explained that power is derived from heat, and that the water and the engine were both to be regarded as agents through which power was applied, and further, that power is always a product of heat. There is, perhaps, no problem in the whole range of mechanics more interesting than to trace the application of this principle in machinery; one that is not only interesting but instructive, and may suggest to the mind of an apprentice a course of investigation that will apply to many other matters connected  with power and mechanics.
The second plan of boring by means of a bar mounted on points or centres is one by which the greatest accuracy is attainable; it is like chuck-boring a lathe operation, and  one for which no better machine than a lathe has been devised, at least for the smaller kinds of work. It is a problem whether in ordinary machine fitting there is not a gain by performing all boring in this manner whenever the rigidity of boring bars is sufficient without auxiliary supports, and when the bars can pass through the work. Machines arranged for this kind of boring can be employed in turning or boring as occasion may require.
"Nothing! But, madame, I want to pay for what I drink!" PREFACE
Balmayne concealed a smile. He had got it. There was only one way in which Hetty could have summoned her lover, and that was by means of the telephone. That there was such an instrument in the house he knew quite well. And why did Hetty Lawrence do this thing? Was she merely frightened, or had she learnt a great deal more than the conspirators imagined?
Leona closed the door behind her with a snap. She was alert and vigorous as a general in action now. She passed downstairs swiftly but firmly, and into the morning room. One by one she snapped up the electric lights till the whole room was bathed in a golden glow.
It was fortunate, perhaps, that the Great Wymering people took their cricket rather seriously. Otherwise, they might have felt, as Doctor Allingham already felt, that there was something impossible about the Clockwork man's performance. He had walked out to the wicket amidst comparative indifference. His peculiar gait might easily have been attributed to sheer nervousness, and his appearance, without flannels, provoked only a slight degree of merriment. When he arrived at the wicket he paused and examined the stumps with great attention, as though wondering what they were for; and it was quite a little while before he arranged himself in the correct attitude before them. He remained standing still, holding the bat awkwardly in the air, and no amount of persuasion on the part of the umpire could induce him to take centre or place his bat to the ground in the recognised fashion. He offered no explanation for his eccentric behaviour, and the fact simply had to be accepted.In the last chapter we considered the philosophy of Plato chiefly under its critical and negative aspects. We saw how it was exclusively from that side that he at first apprehended and enlarged the dialectic of Socrates, how deeply his scepticism was coloured by the religious reaction of the age, and how he attempted, out of his masters mouth, to overturn the positive teaching of the master himself. We saw how, in the Protagoras, he sketched a theory of ethics, which was no sooner completed than it became the starting-point of a still more extended and arduous enquiry. We followed the widening horizon of his speculations until they embraced the whole contemporary life of Hellas, and involved it in a common condemnation as either hopelessly corrupt, or containing within itself the seeds of corruption. We then saw how, by a farther generalisation, he was led to look for the sources of error in the laws of mans sensuous nature and of the phenomenal world with which it holds communion; how, moreover, under the guidance of suggestions coming both from within and from without, he reverted to the earlier schools of Greek thought, and brought their results into parallelism with the main lines of Socratic dialectic. And finally, we watched him planting a firm foothold on the basis of mathematical demonstration; seeking in the very constitution of the soul itself for a derivation of the truths which sensuous experience could not impart, and winning back from215 a more profoundly reasoned religion the hope, the self-confidence, the assurance of perfect knowledge, which had been formerly surrendered in deference to the demands of a merely external and traditional faith. That God alone is wise, and by consequence alone good, might still remain a fixed principle with Plato; but it ceased to operate as a restraint on human aspiration when he had come to recognise an essential unity among all forms of conscious life, which, though it might be clouded and forgotten, could never be entirely effaced. And when Plato tells us, at the close of his career, that God, far more than any individual man, is the measure of all things,133 who can doubt that he had already learned to identify the human and divine essences in the common notion of a universal soul?
