TWO:Euripides is not a true thinker, and for that very reason fitly typifies a period when religion had been shaken to its very foundation, but still retained a strong hold on mens minds, and might at any time reassert its ancient authority with unexpected vigour. We gather, also, from his writings, that ethical sentiment had undergone a parallel transformation. He introduces characters and actions which the elder dramatists would have rejected as unworthy of tragedy, and not only introduces them, but composes elaborate speeches in their defence. Side by side with examples of devoted heroism we find such observations as that everyone loves himself best, and that those are most prosperous who attend most exclusively to their own interests. It so happens that in one instance where Euripides has chosen a subject already handled by Aeschylus, the difference of treatment shows how great a moral revolution had occurred in the interim. The conflict waged between Eteocls and Polyneics for their fathers throne is the theme both of the Seven against Thebes and of the Phoenician Women. In both, Polyneics bases his claim on grounds of right. It had been agreed that he and his brother should alternately hold sway over Thebes. His turn has arrived, and Eteocls refuses to give way. Polyneics endeavours to enforce his pretensions by bringing a foreign army against Thebes. Aeschylus makes him appear before the walls with an allegorical figure of Justice on his shield, promising to restore him to his fathers seat. On hearing this, Eteocls exclaims:"What's the theory here, sir?" Prout asked respectfully.

THREE:There is nothing more interesting, or at the same time more useful, in the study of mechanics, than to analyse the action of cutting machines or other machinery of application, and to ascertain in examples that come under notice whether the main object of a machine is increased force, more accurate guidance, or greater speed than is attainable by hand operations. Cutting machines as explained may be directed to either of these objects singly, or to all of them together, or these objects may vary in their relative importance in different operations; but in all cases where machines are profitably employed, their action can be traced to one or more of the functions named.Before we can come to a decision on this point it will be necessary briefly to recapitulate the statements in question. Socrates is defending himself against a capital charge. He fears that a prejudice respecting him may exist in the minds of the jury, and tries to explain how it arose without any fault of his, as follows:A certain friend of his had asked the oracle at Delphi whether there was any man wiser than Socrates? The answer was that no man was wiser. Not being conscious of possessing any wisdom, great or small, he felt considerably surprised on hearing of this declaration, and thought to convince the god of falsehood by finding out some one wiser than himself. He first went to an eminent politician, who, however, proved, on examination, to be utterly ignorant, with the further disadvantage that it was impossible to convince him of his ignorance. On applying the same test to others a precisely similar result was obtained. It was only the handicraftsmen who could give a satisfactory account of themselves, and their knowledge of one trade made them fancy that they understood everything else equally well. Thus the meaning of the oracle was shown to be that God alone is truly wise, and that of all men he is wisest who, like Socrates, perceives that human wisdom is worth little or nothing. Ever since then, Socrates has made it his business to vindicate the divine veracity by seeking out and exposing every pretender to knowledge that he can find, a line of conduct which has made him extremely unpopular in Athens, while it has also won him a great reputation for wisdom, as people supposed that the matters on which he convicted others of ignorance were perfectly clear to himself.
FORE:In no other branch of machinery has so much research and experiment been made during eighty years past as in steam machinery, and, strange to say, the greater part of this research has been directed to the details of engines; yet there has been no improvement made during the time which has effected any considerable saving of heat or expense. The steam-engines of fifty years ago, considered as steam-using machines, utilised nearly the same proportion of the energy or power developed by the boiler as the most improved engines of modern constructiona fact that in itself indicates that an engine is not the vital part of steam machinery. There is not the least doubt that if the efforts to improve steam-engines had been mainly directed to economising heat and increasing the evaporative power of boilers, much more would have been accomplished with the same amount of research. This remark, however, does not apply to the present day, when the principles of steam-power are so well understood, and when heat is recognised as the proper element to deal with in attempts to diminish the expense of power. There is, of course, various degrees of economy in steam-using as well as in steam-generating machinery; but so long as the best steam machinery does not utilise but one-tenth or one-fifteenth part of the heat represented in the fuel burned, there need be no question as to the point where improvements in such machinery should be mainly directed.Apparently it was quite sufficient. As the gang separated one by one, each was picked up by an officer in plain clothes. The little man in the suede gloves went cautiously on till he came to a working-man's flat off Gray's Inn Road, and here for the first time he became conscious that he was being followed.

FORE:Great crowds walked the long way to Tirlemont. They were constantly threatened by German soldiers, who aimed their rifles at them; passing officers commanded from time to time that some should stay behind, and others were shot. Especially did the clerics amongst the refugees suffer a great deal;145 many were not only scandalously scoffed at, but also maliciously injured. The greater part of the Germans showed a strong anti-Catholic bias, in particular against the clergy, whom they accused of having incited the people against them.47
