FORE:In making designs it is best to employ no references except such as are carried in the memory. The more familiar a person is with machinery of any class, the more able he may be to prepare designs, but not by measuring and referring to other people's plans. Dimensions and arrangement from examples are, by such a course, unconsciously carried into a new drawing, even by the most skilled; besides, it is by no means a dignified matter to collect other people's plans, and by a little combination and modification produce new designs. It may be an easy plan to acquire a certain kind of proficiency, but will most certainly hinder an engineer from ever rising to the dignity of an original designer.

THREE:A true movement of carriages is dependent upon the amount or wearing power of their bearing surface, how this surface is disposed in reference to the strain to be resisted, and the conditions under which the sliding surfaces move; that is, how kept in contact. The cutting strain which is to be mainly considered, falls usually at an angle of thirty to forty degrees downward toward the front, from the centre of the lathe. To resist such strain a flat top shear presents no surface at right angles to the strain; the bearings are all oblique, and not only this, but all horizontal strain falls on one side of the shear only; for this reason, flat top shears have to be made much heavier than would be required if the sum of their cross section could be employed to resist transverse strain. This difficulty can, however, be mainly obviated by numerous cross girts, which will be found in most lathe frames having flat tops.The unhappy man bowed his head trembling,247 and with dull resignation he left the office, strongly escorted.

TWO:Before leaving we went back to the hotel for breakfast. There��it was a first-class hotel��they gave us an apology for coffee, without milk or sugar, and two flimsy pieces of bread, as hard as wood and as black as shoe-polish. I was intensely hungry, and as nowhere at Charleroi anything else could be had, I did my best with the wooden bread and succeeded in washing it down with much chewing and jawing. But the sweet, hard stuff did not suit my digestion, and I felt ill already when at six o'clock we got into the motor-car and left for Dinant.

TWO:VIII."Ah! That is good hearing. You came here tonight expecting to see Ghetti. But we took the liberty of using Ghetti's name. It is only by the merest accident that I am here tonight to carry out this work. My good friends here would have done it for me otherwise. But I was fortunate enough to escape from the gaol yonder, and here I am."

TWO:Turning from sense to reason, Carneades attacks the syllogistic process on grounds already specified in connexion150 with the earlier Sceptics; and also on the plea that to prove the possibility of syllogism is itself to syllogise, and thus involves either a petitio principii or a regress ad infinitum.235 Such a method is, of course, suicidal, for it disproves the possibility of the alleged disproof, a consideration which the Stoics did not fail to urge, and which the later Sceptics could only meet by extending the rule of suspense to their own arguments against argument.236 Nevertheless the sceptical analysis detected some difficulties in the ordinary theory of logic, which have been revived in modern times, and have not yet received any satisfactory solution. Sextus Empiricus, probably copying an earlier authority, it may be Carneades himself, observes that, as the major premise of every syllogism virtually contains the minor, it is either superfluous, or assumes the proposition to be proved. Thus we argue that Socrates is an animal because he is a man, and all men are animals. But if we do not know this latter proposition to be true in the case of Socrates, we cannot be sure that it is true in any case; while if we know it to be true in his case, we do not need to begin by stating it in general terms. And he also attempts to show the impossibility of a valid induction by the consideration, since so often urged, that to generalise from a limited number of instances to a whole class is unsafe, for some of the unknown instances may be contradictory, while the infinite, or at least indefinite multiplicity of individuals precludes the possibility of their exhaustive enumeration.237It was impossible to suspect Hetty of being an actress. The girl was too open and natural for that. And in his queer way Balmayne admired the gentle womanliness of an innocent girl.

THREE: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.The treatment of the passions by the Stoic school presents greater difficulties, due partly to their own vacillation, partly to the very indefinite nature of the feelings in question. It will be admitted that here also the claims of duty are supreme. To follow the promptings of fear or of anger, of pity or of love, without considering the ulterior consequences of our action, is, of course, wrong. For even if, in any particular instance, no harm comes of the concession, we cannot be sure that such will always be the case; and meanwhile the passion is23 strengthened by indulgence. And we have also to consider the bad effect produced on the character of those who, finding themselves the object of passion, learn to address themselves to it instead of to reason. Difficulties arise when we begin to consider how far education should aim at the systematic discouragement of strong emotion. Here the Stoics seem to have taken up a position not very consistent either with their appeals to Nature or with their teleological assumptions. Nothing strikes one as more unnatural than the complete absence of human feeling; and a believer in design might plausibly maintain that every emotion conduced to the preservation either of the individual or of the race. We find, however, that the Stoics, here as elsewhere reversing the Aristotelian method, would not admit the existence of a psychological distinction between reason and passion. According to their analysis, the emotions are so many different forms of judgment. Joy and sorrow are false opinions respecting good and evil in the present: desire and fear, false opinions respecting good and evil in the future.53 But, granting a righteous will to be the only good, and its absence the only evil, there can be no room for any of these feelings in the mind of a truly virtuous man, since his opinions on the subject of good are correct, and its possession depends entirely on himself. Everything else arises from an external necessity, to strive with which would be useless because it is inevitable, foolish because it is beneficent, and impious because it is supremely wise.
