      [Pg 25]Ren had opened the tin with the point of his knife, and was eating sardines and biscuits in a wolfish way. The Chianti he drank from the bottle.

      He had no questions to ask; there was no doubt on his face. If ever a man was telling the simple truth it was Bruce at that moment. There was something like a smile on Maitrank's face when Bruce came to the part that Hetty had played in the stirring drama of the previous night."Not more than usual," said Hetty. "Once I get away from this house I shall be all right, and that looks as if it won't be long."


      CHAPTER VI. ON THE NATURE AND OBJECTS OF MACHINERY.

      "Then you will stay again at the episcopal palace, your Eminence?"After having been searched all over, he was escorted by a sergeant and two soldiers to Tongres, where they took him to Captain Spuer, the same fat officer who, so kindly, had called me a "swine."

      A book containing the pattern record should be kept, in which these catalogue numbers are set down, with a short description to identify the different parts to which the numbers belong, so that all the various details of any machine can at any time be referred to. Besides this description, there should be opposite the catalogue of pattern numbers, ruled spaces, in which to enter the weight of castings, the cost of the pattern, and also the amount of turned, planed, or bored surface on each piece when it is finished, or the time required in fitting, which is the same thing. In this book the assembled parts of each machine should be set down in a separate list, so that orders for castings can be made from the list without other references. This system is the best one known to the writer, and is in substance a plan now adopted in many of the best engineering establishments. A complete system in all things pertaining to drawings and classifications should be rigidly adhered to; any plan is better than none, and the schooling of the mind to be had in the observance of systematic rules is a matter not to be neglected. New plans for promoting system may at any time arise, but such plans cannot be at any [87] time understood and adopted except by those who have cultivated a taste for order and regularity.There were three kinds of strain mentionedtorsional, deflective, and accidental. To meet these several strains the same means have to be provided, which is a sufficient size and strength to resist them; hence it is useless to consider each of these different strains separately. If we know which of the three is greatest, and provide for that, the rest, of course, may be disregarded. This, in practice, is found to be accidental strains to which shafts are in ordinary use subjected, and they are usually made, in point of strength, far in excess of any standard that would be fixed by either torsional or transverse strain due to the regular duty performed.

      Considered as a mechanical agent, a hammer concentrates the power of the arms, and applies it in a manner that meets the requirements of various purposes. If great force is required, a long swing and slow blows accomplish tons; if but little force is required, a short swing and rapid blows will servethe degree of force being not only continually at control, but also the direction in which it is applied. Other mechanism, if employed instead of hammers to perform a similar purpose, would require to be complicated [104] machines, and act in but one direction or in one plane.

      Next to its bearing on the question of immortality, the Epicurean psychology is most interesting as a contribution to the theory of cognition. Epicurus holds that all our knowledge is derived from experience, and all our experience, directly or indirectly, from the presentations of sense. So far he says no more than would be admitted by the Stoics, by Aristotle, and indeed by every Greek philosopher except Plato. There is, therefore, no necessary connexion between his views in this respect and his theory of ethics, since others had combined the same views with a very different standard of action. It is in discussing the vexed question of what constitutes the ultimate criterion of truth that he shows to most disadvantage in comparison with the more intellectual96 schools. He seems to have considered that sensation supplies not only the matter but the form of knowledge; or rather, he seems to have missed the distinction between matter and form altogether. What the senses tell us, he says, is always true, although we may draw erroneous inferences from their statements.184 But this only amounts to the identical proposition that we feel what we feel; for it cannot be pretended that the order of our sensations invariably corresponds to the actual order of things in themselves. Even confining ourselves to individual sensations, or single groups of sensations, there are some that do not always correspond to the same objective reality, and others that do not correspond to any reality at all; while, conversely, the same object produces a multitude of different sensations according to the subjective conditions under which it affects us. To escape from this difficulty, Epicurus has recourse to a singularly crude theory of perception, borrowed from Empedocles and the older atomists. What we are conscious of is, in each instance, not the object itself, but an image composed of fine atoms thrown off from the surfaces of bodies and brought into contact with the organs of sense. Our perception corresponds accurately to an external image, but the image itself is often very unlike the object whence it originally proceeded. Sometimes it suffers a considerable change in travelling through the atmosphere. For instance, when a square tower, seen at a great distance, produces the impression of roundness, this is because the sharp angles of its image have been rubbed off on the way to our eyes. Sometimes the image continues to wander about after its original has ceased to exist, and that is why the dead seem to revisit us in our dreams. And sometimes the images of different objects coalesce as they are floating about, thus producing the appearance of impossible monsters, such as centaurs and chimaeras.185`Plot highly improbable. Characterization exaggerated.
