× FORE:In speaking of the mechanical knowledge to be gained, and of the privileges afforded for learners in engineering-works in a general way, it must, of course, be assumed that such works afford full facilities for learning some branch of work by the best practice and in the most thorough manner. Such establishments are, however, graded from the highest class, on the best branches of work, where a premium would be equitable, down [23] to the lowest class, performing only inferior branches of work, where there can be little if any advantage gained by serving an apprenticeship.

× FORE:On the Thursday of the week of destruction the inhabitants were notified that they had to leave the town, but Professor Noyons and his wife decided to stay on, as they could not leave the one hundred and fifty wounded men who were laid up at the Institution.

× FORE:The unhappy man asserted in a loud voice that183 he was innocent, but got the answer that he would have to prove that later on. But he never had a chance of doing that. Arriving at the market-place, he and three others were simply placed against the wall and shot. He could not even have spiritual assistance.

× FORE:A few guests of the higher Bohemian type still lingered, but with easy tact the hostess contrived to get rid of them. Her absence had not been noticed, the little escapade on the motor was not mentioned.That the absolute disjunction of thought from matter involved the impossibility of their interaction, was a consequence not drawn by Descartes himself, but by his immediate followers. Here also, Greek philosophy played its part in hastening the development of modern ideas. The fall of Aristotle had incidentally the effect of reviving not only the systems which preceded, but also those which followed his. Chief among these were Stoicism and Epicureanism. Differing widely in most other respects, they agreed in teaching that body is acted on by body alone. The Cartesians accepted this principle to the fullest extent so far as human perceptions and volitions were concerned; and to a great extent in dealing with the problems of physical science. But instead of arguing from the laws of mechanical causation to the materiality of mind, they argued from its immateriality to the total absence of communication between consciousness and motion. There was, however, one thinker of that age who went all lengths with the later Greek materialists. This was Thomas Hobbes, the founder of modern ethics, the first Englishman to grasp and develope still further Galileo��s method of mathematical deduction and mechanical analysis.

× FORE:"Ah, you are a good girl. If I had seen more like you I should have been a better man. But I was brought up in a hard school. It's about Mamie. Did it ever strike you that the child was no relation to Leona Lalage?"Noting the causes and conditions which have led to this perfection in machine-tool manufacture, and how far they apply in the case of other classes of machinery, will in a measure indicate the probable improvements and changes that the future will produce.

× FORE:Leaving out the matter of a positive relative movement between shafts, which belts as a means of transmitting power cannot insure, there are the following conditions that must be considered in determining whether belts or other means should be employed in transmitting power from one machine to another or between the parts of machines.The division of matter into minute and indestructible particles served admirably to account for the gradual formation and disappearance of bodies without necessitating the help of a creator. But the infinities assumed as a condition of atomism were of even greater importance. Where time and space are unlimited, the quantity of matter must be equally unlimited, otherwise, being composed of loose particles, it would long since have been dissipated and lost in the83 surrounding void. Now, given infinite time and space, and infinite atoms capable of combining with one another in various ways, all possible combinations must already have been tried, not once or twice, but infinitely often. Of such combinations, that which best fulfils the conditions of mechanical stability will last the longest, and, without being designed, will present all the characters of design. And this, according to Epicurus, is how the actual frame of things comes to be what it is. Nor was it only the world as a whole that he explained by the theory of a single happy accident occurring after a multitude of fortuitous experiments. The same process repeats itself on a smaller scale in the production of particular compounds. All sorts of living bodies were originally throw up from the earth��s bosom, but many of them instantly perished, not being provided with the means of nutrition, propagation, or self-defence. In like manner we are enabled to recall a particular thought at pleasure, because innumerable images are continually passing through the mind, none of which comes into the foreground of consciousness until attention is fixed on it; though how we come to distinguish it from the rest is not explained. So also, only those societies survived and became civilised where contracts were faithfully observed. All kinds of wild beasts have at different times been employed in war, just as horses and elephants are now, but on trial were found unmanageable and given up.162
