ONE:Engines operated by means of hot air, called caloric engines, and engines operated by gas, or explosive substances, all act substantially upon the same general principles as steam-engines; the greatest distinction being between those engines wherein the generation of heat is by the combustion of fuel, and those wherein heat and expansion are produced by chemical action. With the exception of a limited number of caloric or air engines, steam machinery comprises nearly all expansive engines that are employed at this day for motive-power; and it may be safely assumed that a person who has mastered the general principles of steam-engines will find no trouble in analysing and understanding any machinery acting from expansion due to heat, whether air, gas, or explosive agents be employed.

TWO:"It is always thus in books," Leona said, with a hard smile.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.

THREE:Bruce plunged into his story. He had a most interested listener. The small grey eyes of the listener were fixed intently on the narrator's face. The black cigar died out between his fingers.Pencil-work is indeed the main operation, the inking being merely to give distinctness and permanency to the lines. The main thing in pencilling is accuracy of dimensions and stopping the lines where they should terminate without crossing others. The best pencils only are suitable for draughting; if the plumbago is not of the best quality, the points require to be continually sharpened, and the pencil is worn away at a rate that more than makes up the difference in cost between the finer and cheaper grades of pencils, to say nothing of the effect upon a drawing.

FORE:The road along which I walked, the main road between Vis and Lige, was laid under fire from various forts, and every moment I saw on my left clouds rise up from the rocky heights that run along the whole of the Meuse. These clouds were partly formed by smoke from the guns mounted by the Germans against the forts, partly by volumes of earth thrown up by the projectiles from the broken-up soil.CHAPTER XLIX. IN THE DEAD OF THE NIGHT.
THREE:The commander ruled with a strong hand. They issued not only the usual proclamations about introducing German time, but the commander went even so far as to dictate at what hour the Holy Masses had to be said. In one of the proclamations I read, for example, that in future the Mass of six o'clock, Belgian time, had to be said at the same hour German time. Another proclamation said that skippers were forbidden to sail, and that all boats, including fisher-boats, had been seized.Youre a fine Sky Patrol, he grumbled. You swallowed everything he said, like a big softie! And told him everything you knew, he continued, bitterly.

FORE:Xenophon gives the same interest a more edifying direction when he enlivens the dry details of his Cyropaedia with touching episodes of conjugal affection, or presents lessons in domestic economy under the form of conversations between a newly-married couple.107 Plato in some respects transcends, in others falls short of his less gifted contemporary. For his doctrine of love as an educating processa true doctrine, all sneers and perversions notwithstandingthough readily applicable to the relation of the sexes, is not applied to it by him; and his project of a common training for men and women, though suggestive of a great advance on the existing system if rightly carried out, was, from his point of view, a retrograde step towards savage or even animal life, an attempt to throw half the burdens incident to a military organisation of society on those who had become absolutely incapable of bearing them.

FORE:"Will you be so good as to tell me how?" Balmayne said.
In the use of hydraulic apparatus for transmitting and applying power, there is, however, this difficulty to be contended with: water is inelastic, and for the performance of irregular duty, there is a loss of power equal to the difference between the duty that a piston may perform and what it does perform; that is, the amount of water, and consequently the amount of power given off, is as the movement and volume of the water, instead of as the work done. The application of hydraulic machinery to the lifting and handling of weights will be further noticed in another place.On August 25th the Antwerp garrison made a sortie, in the direction of Louvain. At the beginning the Belgians were successful, and came within four and a half miles of this town. For a moment the situation became critical, and at about seven o'clock a small troop of cavalry came at a furious gallop from the scene of battle to Louvain, probably to summon the assistance of the garrison.Porphyry observes that the first series of essays show the immaturity of youtha period which he extends to what is generally considered the sufficiently ripe age of fifty-nine;the second series the full-grown power of manhood; and the last the weakness of declining years. The truth is that his method of criticism, at least in this instance, was to judge of compositions as if their merit depended on their length, and perhaps also with reference to the circumstance whether their subject had or had not been previously talked over with himself. In point of fact, the earlier pieces include some of the very best things that Plotinus ever wrote; and, taking them in the order of their composition, they form a connected279 exposition of Neo-Platonic principles, to which nothing of importance was ever added. This we shall attempt to show in the most effectual manner possible by basing our own account of Neo-Platonism on an analysis of their contents; and we strongly recommend them to the attention of all Greek scholars who wish to make themselves acquainted with Plotinus at first hand, but have not leisure to wade through the whole of his works. It may also be mentioned that the last series of essays are distinguished by the popular character of their subjects rather than by any evidence of failing powers, one of them, that on Providence,417 being remarkable for the vigour and eloquence of its style.
