      Professor John Sweet of Cornell University, in America, while delivering an address to the mechanical engineering classes, during the same year, made use of the following words: "It is [5] not what you 'know' that you will be paid for; it is what you can 'perform,' that must measure the value of what you learn here." These few words contain a truth which deserves to be earnestly considered by every student engineer or apprentice; as a maxim it will come forth and apply to nearly everything in subsequent practice.For manufacturing processes, one importance of steam-power rests in the fact that such power can be taken to the material; and beside other advantages gained thereby, is the difference in the expense of transporting manufactured products and the raw material. In the case of iron manufacture, for example, it would cost ten times as much to transport the ore and the fuel used in smelting as it does to transport the manufactured iron; steam-power saves this difference, and without such power our present iron traffic would be impossible. In a great many manufacturing processes steam is required for heating, bleaching, boiling, and so on; besides, steam is now to a large extent employed for warming buildings, so that even when water or other power is employed, in most cases steam-generating apparatus has to be set up in addition. In many cases waste [31] steam or waste heat from a steam-engine can be employed for the purposes named, saving most of the expense that must be incurred if special apparatus is employed.

      "She can't want you half so badly as I do," Gordon laughed as he bent down and kissed the shy lips. "And that queer little creature will have to learn to do without you altogether before long. Four new patients today, Hetty. And I have taken the house in Green-Street.""It's my duty, madame," Prout began, "to ask you to----"


      Fifth.The range and power of the blows, as well as the time in which they are delivered, is controlled at will; this constitutes the greatest distinction between steam and other hammers, and the particular advantage which has led to their extended use.

      The concessions to common sense and to contemporary schools of thought, already pointed out in those Dialogues which we suppose to have been written after the Republic, are still more conspicuous in the Laws. We do not mean merely the project of a political constitution avowedly offered as the best possible in existing circumstances, though not the best absolutely; but we mean that there is throughout a desire to present philosophy from its most intelligible, practical, and popular side. The extremely rigorous standard of sexual morality (p. 838) seems, indeed, more akin to modern than to ancient notions, but it was in all probability borrowed from the naturalistic school of ethics, the forerunner of Stoicism; for not only is there a direct appeal to Natures teaching in that connexion; but throughout the entire work the terms nature and naturally occur with greater frequency, we believe, than in all the rest of Platos writings put together. When, on the other hand, it is asserted that men can be governed by no other motive than pleasure (p. 663, B), we seem to see in this declaration a concession to the Cyrenaic school, as well as a return to the forsaken standpoint of the Protagoras. The increasing influence of Pythagoreanism is shown by271 the exaggerated importance attributed to exact numerical determinations. The theory of ideas is, as Prof. Jowett observes, entirely absent, its place being taken by the distinction between mind and matter.159

      "I remember the transaction perfectly well," he said. "We do a lot of money-changing and that kind of thing, as our foreign connection is a large one. I should not have heeded the matter but for noticing the curious disfigurement of the man's hands."They sang and shouted and waved their arms. Most of them carried bottles full of liquor, which they put to their mouths frequently, smashed them on the ground, or handed them to their comrades, when unable to drink any more themselves. Each of a troop of cavalry had a bottle of pickles, and enjoyed them immensely.

      The cardinal's face was overclouded suddenly, and quietly he answered:In the theory of reasoning the simple proposition is taken as a starting-point; but instead of deducing the syllogism379 from the synthesis of two premises, Aristotle reaches the premises through the conclusion. He tells us, indeed, that reasoning is a way of discovering from what we know, something that we did not know before. With him, however, it is really a process not of discovery but of proof. He starts with the conclusion, analyses it into predicate and subject or major and minor, and then, by a further analysis, introduces a middle term connecting the two. Thus, we begin with the proposition, Caius is mortal, and prove it by interpolating the notion humanity between its two extremes. From this point of view the premises are merely a temporary scaffolding for bringing the major and minor into connexion with the middle term; and this is also the reason why Aristotle recognises three syllogistic figures only, instead of the four admitted by later logicians. For, the middle may either be contained in one extreme and contain the other, which gives us the first figure; or it may contain both, which gives the second figure; or be contained in both, which gives the third; and this is an exhaustive enumeration of the possible combinations.274
