THREE:Zeller, while taking a much wider view than Hegel, still assumes that Plato��s reforms, so far as they were suggested by experience, were simply an adaptation of Dorian practices.148 He certainly succeeds in showing that private property, marriage, education, individual liberty, and personal morality were subjected, at least in Sparta, to many restrictions resembling those imposed in the Platonic state. And Plato himself, by treating the Spartan system as the first form of degeneration from his own ideal, seems to indicate that this of all existing polities made the nearest approach to it. The declarations of the Timaeus149 are, however, much more distinct; and according to them it was in the caste-divisions of Egypt that he found the nearest parallel to his own scheme of social reorganisation. There, too, the priests, or wise men came first, and after them the warriors, while the different branches of industry were separated from one another by rigid demarcations. He may also have been struck by that free admission of women to employments elsewhere filled exclusively by men, which so surprised Herodotus, from his inability to discern its real cause��the more advanced differentiation of Egyptian as compared with Greek society.150Cutting, as a process in converting material, includes the force to propel cutting edges, means to guide and control their action, and mechanism to sustain and adjust the material acted upon. In cutting with hand tools, the operator performs the two functions of propelling and guiding the tools with his hands; but in what [58] is called power operations, machines are made to perform these functions. In nearly all processes machines have supplanted hand labour, and it may be noticed in the history and development of machine tools that much has been lost in too closely imitating hand operations when machines were first applied. To be profitable, machines must either employ more force, guide tools with more accuracy, or move them at greater speed, than is attainable by hand. Increased speed may, although more seldom, be an object in the employment of machinery, as well as the guidance of implements or increased force in propelling them. The hands of workmen are not only limited as to the power that may be exerted, and unable to guide tools with accuracy, but are also limited to a slow rate of movement, so that machines can be employed with great advantage in many operations where neither the force nor guidance of tools are wanting.

FORE:I felt very sick, for the sweet rye-bread which I had forced down my throat in the morning did not agree with me at all. At last I felt so ill that I162 was obliged to lie down on the floor of the car, and it took my colleague all his time to convince me that he did not think that my last hour had struck. FORE:
