A carriage moving on angular ways always moves steadily and easily, without play in any direction until lifted from its bearing, which rarely happens, and its lifting is easily opposed by adjustable gibs. A carriage on a flat shear is apt to have play in a horizontal direction because of the freedom which must exist to secure easy movement. In the case of tracks, it may also be mentioned that the weight of a carriage acts as a constant force to hold it steady, while with a flat shear the weight of a carriage is in a sense opposed to the ways, and has no useful effect in steadying or guiding. The rigidity and steadiness of tool movement is notoriously in favour of triangular tracks, so much so that nearly all American machine tool-makers construct lathes in this manner, although it adds no inconsiderable cost in fitting.Another form of naturalistic religion, fitted for universal acceptance by its appeals to common experience, was the worship of the Sun. It was probably as such that Mithras, a Syro-Persian deity, obtained a success throughout the Roman empire which at one time seemed to balance the rising fortunes of Christianity. Adoration of the heavenly bodies was, indeed, very common during this period, and was probably connected with the extreme prevalence of astrological superstition. It would also harmonise perfectly with the still surviving Olympian religion of the old Hellenic aristocracy, and would profit by the support which philosophy since the time of Socrates had extended to this form of supernaturalist belief. But, perhaps, for that very reason the classes which had now216 become the ultimate arbiters of opinion, felt less sympathy with Mithras-worship and other kindred cults than with the Egyptian mysteries. These had a more recognisable bearing on their own daily life, and, like the Chthonian religions of old Greece, they included a reference to the immortality of the soul. Moreover, the climate of Europe, especially of western Europe, does not permit the sun to become an object of such excessive adoration as in southern Asia. Mithras-worship, then, is an example of the expansive force exhibited by Oriental ideas rather than of a faith which really satisfied the wants of the Roman world.
FORE:A few guests of the higher Bohemian type still lingered, but with easy tact the hostess contrived to get rid of them. Her absence had not been noticed, the little escapade on the motor was not mentioned.There were three kinds of strain mentionedtorsional, deflective, and accidental. To meet these several strains the same means have to be provided, which is a sufficient size and strength to resist them; hence it is useless to consider each of these different strains separately. If we know which of the three is greatest, and provide for that, the rest, of course, may be disregarded. This, in practice, is found to be accidental strains to which shafts are in ordinary use subjected, and they are usually made, in point of strength, far in excess of any standard that would be fixed by either torsional or transverse strain due to the regular duty performed.
The Countess bowed; not for an instant did she change colour."Found out a lot," said the first policeman. "This motor's as bright as your lantern really, It's all covered over with blacklead."The second includes what is called threading in America and screwing in England. Machines for this purpose consist essentially of mechanism to rotate either the blank to be cut or the dies, and devices for holding and presenting the blanks.It seems to us that Hegel, in his anxiety to crush every historical process into the narrow symmetry of a favourite metaphysical formula, has confounded several entirely distinct conceptions under the common name of subjectivity. First, there is the right of private judgment, the claim of each individual to have a voice in the affairs of the State, and to have the free management of his own personal concerns. But this, so far from being modern, is one of the oldest customs of the Aryan race; and perhaps, could we look back to the oldest history of other races now despotically governed, we should find it prevailing among them also. It was no new nor unheard-of privilege that Rousseau vindicated for the peoples of his own time, but their ancient birthright, taken from them by the growth of a centralised military system, just as it had been formerly taken from the city communities of the Graeco-Roman world. In this respect, Plato goes against the whole248 spirit of his country, and no period of its development, not even the age of Homer, would have satisfied him.
