TWO:No subject connected with mechanics has been more thoroughly investigated than that of gearing. Text-books are replete with every kind of information pertaining to wheels, at least so far as the subject can be made a mathematical one; and to judge from the amount of matter, formul?, and diagrams, relating to the teeth of wheels that an apprentice will meet with, he will no doubt be led to believe that the main object of modern engineering is to generate wheels. It must be admitted that the teeth of wheels and the proportions of wheels is a very important matter to understand, and should be studied with the greatest care; but it is equally important to know how to produce the teeth in metal after their configuration has been defined on paper; to understand the endurance of teeth under abrasive wear when made of wrought or cast iron, brass or steel; how patterns can be constructed from which correct wheels may be cast, and how the teeth of wheels can be cut [52]by machinery, and so on.

- THREE:IV.The man merely made a gesture with his hands. Then followed a sign, by which Bruce knew that he was speaking to a dumb man, a startling affliction for a smart chauffeur.
- THREE:On Alexanders departure for the East, Aristotle returned to Athens, where he now placed himself at the head of a new philosophical school. The ensuing period of thirteen years288 was fully occupied by the delivery of public lectures, and by the composition of those encyclopaedic writings which will preserve his memory for ever, along, perhaps, with many others which have not survived. Like Anaxagoras, he was not allowed to end his days in the city of his adoption. His youthful attacks on Isocrates had probably made him many enemies among that rhetors pupils. It is supposed by Grote, but warmly disputed by Zeller, that his trenchant criticisms on Plato had excited a similar animosity among the sectaries of the Academy.178 Anyhow, circumstances had unavoidably associated him with the detested Macedonian party, although his position, as a metic, or resident alien, debarred him from taking any active part in politics. With Alexanders death the storm broke loose. A charge was trumped up against Aristotle, on the strength of his unlucky poem in honour of Hermeias, which was described as an insult to religion. That such an accusation should be chosen is characteristic of Athenian bigotry, even should there be no truth in the story that certain philosophical opinions of his were likewise singled out for prosecution. Before the case came on for trial, Aristotle availed himself of the usual privilege allowed on such occasions, and withdrew to Chalcis, in order, as he said, that the Athenians need not sin a second time against philosophy. But his constitution, naturally a feeble one, was nearly worn out. A year afterwards he succumbed to a stomach complaint, aggravated, if not produced, by incessant mental application. His contemporary, Demosthenes, perished about the same time, and at the same age, sixty-two. Within little more than a twelvemonth the world had lost its three greatest men; and after three centuries of uninterrupted glory, Hellas was left unrepresented by a single individual of commanding genius.
TWO:They never left Louvain. On August 25th information was sent to the Leo XIII Institution for Philosophy, a building turned into a hospital, that a hundred wounded men might be expected towards evening. That evening began the wild shooting and burning of houses by the Germans, and soon a large number of wounded was taken to the Institution. Suddenly Professor Noyons recognised one of his servants among the wounded who were brought to him for treatment. She had three bullets in her side. After having bandaged her wounds, he hurried away to his house, in order to see what had happened."Then you will stay again at the episcopal palace, your Eminence?"

TWO:At Tirlemont they were very busy rebuilding the burnt houses, although all day long the air shook from the heavy roar of the cannon near Antwerp.
