THREE:Assuming, for example, that a machine will cost as much as the wages of an attendant for one year, which is not far from an average estimate for iron working machine tools, and that interest, wear, and repairs amount to ten per cent. on this sum, then the attendance would cost ten times as much as the machine; in other words, the wages paid to a workman to attend a machine is, on an average, ten times as much as the other expenses attending its operation, power excepted. This assumed, it follows that in machine tools any improvement directed to labour saving is worth ten times as much as an equal improvement directed to the economy of first cost.
FORE:"Because my bedroom clock struck the hour as I got back. I heard somebody leave the corner house. I looked out of the window and saw a motor car that appeared to be draped in black. As a woman from the house got on to it she seemed to push some of the drapery aside, for I saw the gleam of the rail. She was a fair woman with a mantilla over her head. The car went off without the faintest noise, and that is all I know."

FORE:Hetty gave the desired information. There was a peculiar smile on the face of her companion.The reasons that favour combination of functions in machines, and the effects that such combinations may produce, are so various that the problem has led to a great diversity of opinions and practice among both those who construct and even those who employ machines. It may be said, too, that a great share of the combinations found in machines, such as those to turn [68], mill, bore, slot, and drill in iron fitting, are not due to any deliberate plan on the part of the makers, so much as to an opinion that such machines represent a double or increased capacity. So far has combination in machines been carried, that in one case that came under the writer's notice, a machine was arranged to perform nearly every operation required in finishing the parts of machinery; completely organised, and displaying a high order of mechanical ability in design and arrangement, but practically of no more value than a single machine tool, because but one operation at a time could be performed.

FORE: His [Aristotles] theory of syllogism is simply an explicit statement of the fact that all knowledge, all thought, rests on universal truths or general propositionsthat all knowledge, whether deductive or inductive, is arrived at by the aid, the indispensable aid, of general propositions. We in England have been almost charmed into the belief that reasoning is perpetually from particular to particular, and a village matron and her Lucy have been used to express the truth for us in the concrete form adapted to our weaker comprehension (Mills Logic, bk. ii. ch. 3). We shall next be told, forsooth, that oxygen and hydrogen do not enter into the composition of water, because our village matron perpetually drinks it without passing through either element, and the analysis of the chemist will be proved as great a fiction as the analysis of the logician. Aristotle has supplied the links which at once upset all such superficial389 analysis. He has shown that even in analogy or example, which apparently proceeds in this way from one particular instance to another particular instance, we are only justified in so proceeding in so far as we have transformed the particular instance into a general proposition.284Dreams, like oracles, were occasionally employed for the conversion of infidels. An incident of the kind is related by Aelian, a writer who flourished early in the third century, and who is remarkable, even in that age, for his bigoted orthodoxy. A certain man named Euphronius, he tells us, whose delight was to study the blasphemous nonsense of Epicurus, fell very ill of consumption, and sought in vain for help from the skill of the physicians. He was already at deaths door, when, as a last resource, his friends placed him in the temple of Asclpius. There he dreamed that a priest came to him and said, This mans only chance of salvation is to burn the impious books of Epicurus, knead the ashes up with wax, and use the mixture as a poultice for his chest and stomach. On awakening, he followed the divine prescription, was restored to health, and became a model of piety for the rest of his life. The same author gives us a striking instance of prayer answered, also redounding to the credit of Asclpius, the object of whose favour is, however, on this occasion not a human being but a fighting-cock. The scene is laid at Tanagra, where the bird in question, having had his foot hurt, and evidently acting under the influence of divine inspiration, joins a choir who are singing the praises of Asclpius, contributing his share to the sacred concert, and, to the best of his ability, keeping time with the other performers. This he did, standing on one leg and stretching out the other, as if to show its pitiable condition. So he sang to his saviour as far as the strength of his voice would permit, and prayed that he might recover the use of his limb. The petition is granted,230 whereupon our hero claps his wings and struts about with outstretched neck and nodding crest like a proud warrior, thus proclaiming the power of providence over irrational animals.352
