THREE:Milling tools are employed at Crewe for roughing out the slots in locomotive crank axles. A number of detachable tools are mounted on a strong disc, so that four to six will act at one time; in this way the displacement exceeds what a lathe can perform when acting continuously with two tools. Rotary planing machines constructed on the milling principle, have been tried for plane surfaces, but with indifferent success, except for rough work.We have now to show what new beliefs gained most ground, and what old beliefs were most successfully revived, through the combination of favourable conditions, an analysis of which has been attempted in the preceding pages. Among the host of creeds which at this period competed with one another for the favour of the rich or for the suffrages of the poor, there were some that possessed a marked advantage over their rivals in the struggle for existence. The worship of Nature considered as imaging the vicissitudes of human life, could not fail to be the most popular of any. All who desired a bond of sympathy uniting them with their fellow-subjects over the whole empire, and even with the tribes beyond its frontiers, might meet on this most universal ground. All who wished to combine excitement with devotion were attracted by the dramatic representation of birth and death, of bereavement and sorrow and searching, of purification through suffering, and triumphant reunion with the lost objects of affection in this or in another world. Inquisitive or innovating minds were gratified by admission to secrets a knowledge of which was believed to possess inestimable value. And the most conservative could see in such celebrations an acknowledgment, under other forms, of some divinity which had always been reverenced in their own home, perhaps even the more authentic reproduction of adventures already related to them as dim and uncertain traditions of the past. More than one such cultus, representing under the traits of personal love and loss and recovery, the death of vegetation in winter and its return to life in spring, was introduced from the East, and obtained a wide popularity through the empire. Long before the close of the republic, the worship of Cybele was established in Rome with the sanction of the Senate. Other Asiatic deities of a much less respectable character, Astarte and the so-called Syrian goddess, though not officially215 recognised, enjoyed a celebrity extending to the remotest corners of the western world.327 Still greater and more universal was the veneration bestowed on Isis and Serapis. From the prince to the peasant, from the philosopher to the ignorant girl, all classes united in doing homage to their power. Their mysteries were celebrated in the mountain valleys of the Tyrol, and probably created as much excitement among the people of that neighbourhood as the Ammergau passion-play does at present.328 An inscription has been discovered describing in minute detail an offering made to Isis by a Spanish matron in honour of her little daughter. It was a silver statue richly ornamented with precious stones, resembling, as our authority observes, what would now be presented to the Madonna,329 who indeed is probably no more than a Christian adaptation of the Egyptian goddess. And Plutarch, or another learned and ingenious writer whose work has come down to us under his name, devotes a long treatise to Isis and Osiris, in which the mythical history of the goddess is as thickly covered with allegorical interpretations as the statue dedicated to her by the Spanish lady was with emeralds and pearls.
THREE:Aristotle has sometimes been represented as an advocate of free-will against necessity. But the question had not really been opened in his time. He rejected fatalism; but it had not occurred to him that internal motives might exercise a constraining power over action. Nor has his freedom anything to do with the self-assertion of mind, its extrication from the chain of physical antecedents. It is simply the element of397 arbitrariness and uncertainty supposed to characterise the region of change and opposition, as distinguished from the higher region of undeviating regularity.

TWO:"All in good time," Charlton replied. "Now I have found you once again I can punish you and clear my wife's good name at the same time. I have only to lock the door and summon the police by way of the window. If everything else fails I can have you punished for the theft of those jewels."Machines and tools operating by percussive action, although they comprise a numerous class, and are applied in nearly all mechanical operations, have never received that amount of attention in text-books which the importance of the machines and their extensive use calls for. Such machines have not even been set off as a class and treated of separately, although the distinction is quite clear between machines with percussive action, and those with what may be termed direct action, both in the manner of operating and in the general plans of construction. There is, of course, no lack of formul? for determining the measure of force, and computing the dynamic effect of percussive machines acting against a measured or assumed resistance, and so on; but this is not what is meant. There are certain conditions in the operation of machines, such as the strains which fall upon supporting frames, the effect produced upon malleable material when struck or pressed, and more especially of conditions which may render percussive or positive acting machines applicable to certain purposes; but little explanation has been given which is of value to practical men.
