It is generally a safe rule to assume that any custom long and uniformly followed by intelligent people is right; and, in the absence of that experimental knowledge which alone enables one to judge, it is safe to receive such customs, at least for a time, as being correct."Wrong?" Lawrence cried as he paced the room. "Not much. Why, you are giving me the master key to the situation. Look me up again this evening. I guess I shall be able to astonish you. I'm off to Frampton's now. I must have a copy of that paper if it costs me a hundred pounds."<024>

THREE:The systematising power of Aristotle, his faculty for bringing the isolated parts of a surface into co-ordination and continuity, is apparent even in those sciences with whose material truths he was utterly unacquainted. Apart from the falseness of their fundamental assumptions, his scientific treatises are, for their time, masterpieces of method. In this respect they far surpass his moral and metaphysical works, and they are also written in a much more vigorous style, occasionally even rising into eloquence. He evidently moves with much more assurance on the solid ground of external nature than in the cloudland of Platonic dialectics, or among the possibilities of an ideal morality. If, for example, we open his Physics, we shall find such notions as Causation, Infinity, Matter, Space, Time, Motion, and Force, for the first time in history separately discussed, defined, and made the foundation of natural philosophy. The treatise On the Heavens very properly regards the celestial movements as a purely mechanical problem, and strives throughout to bring theory and practice327 into complete agreement. While directly contradicting the truths of modern astronomy, it stands on the same ground with them; and anyone who had mastered it would be far better prepared to receive those truths than if he were only acquainted with such a work as Platos Timaeus. The remaining portions of Aristotles scientific encyclopaedia follow in perfect logical order, and correspond very nearly to Auguste Comtes classification, if, indeed, they did not directly or indirectly suggest it. We cannot, however, view the labours of Aristotle with unmixed satisfaction until he comes on to deal with the provinces of natural history, comparative anatomy, and comparative psychology. Here, as we have shown, the subject exactly suited the comprehensive observation and systematising formalism in which he excelled. Here, accordingly, not only the method but the matter of his teaching is good. In theorising about the causes of phenomena he was behind the best science of his age; in dissecting the phenomena themselves he was far before it. Of course very much of what he tells was learned at second-hand, and some of it is not authentic. But to collect such masses of information from the reports of uneducated hunters, fishermen, grooms, shepherds, beemasters, and the like, required an extraordinary power of putting pertinent questions, such as could only be acquired in the school of Socratic dialectic. Nor should we omit to notice the vivid intelligence which enabled even ordinary Greeks to supply him with the facts required for his generalisations. But some of his most important researches must be entirely original. For instance, he must have traced the development of the embryo chicken with his own eyes; and, here, we have it on good authority that his observations are remarkable for their accuracy, in a field where accuracy, according to Caspar Friedrich Wolff, is almost impossible.210"Have they given you back everything?"

By Elena Smith

Starting in the early morning of August 15th, I arrived at Vis without much trouble, after having been led across the Lixhe bridge once more. Since my first visit the bridge had been destroyed three times over, and this new one seemed very weak. As I stood there looking at it, a motor lorry had to cross it, and the bridge gave way near the bank. Another motor had then to pull the lorry up to the top of the bank, and this made the bridge give way still further.This proposition argues the expediency of reducing the proportions of mill gearing and increasing its speed, a change which has gradually been going on for fifty years past; but there are opposing conditions which make a limit in this direction, such as the speed at which bearing surfaces may run, centrifugal strain, jar, and vibration. The object is to fix upon a point between what high speed, light weight, cheapness of cost suggest, and what the conditions of practical use and endurance demand.
