FORE:I walked about a little longer to examine the damage done. The fine Pont des Arches was for the greater part destroyed by the retreating Belgians, as well as the Pont Maghin. This is a pity, especially as regards the first-named bridge, so famous as a work of art, and the more so as other bridges had not been touched and could be used by the Germans. The bombardment did not damage the town to any great extent, but it was remarkable that the largest houses had suffered most."7. Colleaux, senator.

THREE:It would appear that even in the Pythagorean school there had been a reaction against a doctrine which its founder had been the first to popularise in Hellas. The Pythagoreans had always attributed great importance to the conceptions of harmony and numerical proportion; and they soon came to think of the soul as a ratio which the different elements of the animal body bore to one another; or as a musical concord resulting from the joint action of its various members, which might be compared to the strings of a lute. ButThe most perfect castings for gear wheels and pulleys and other pieces which can be so moulded, are made by drawing the patterns through templates without rapping. These templates are simply plates of metal perforated so that the pattern can be forced through them by screws or levers, leaving the sand intact. Such templates are expensive to begin with, because of the accurate fitting that is required, especially around the teeth of wheels, and the mechanism that is required in drawing the patterns, but when a large number of pieces are to be made from one pattern, such as gear wheels and pulleys, the saving of labour will soon pay for the templates and machinery required, to say nothing of the saving of metal, which often amounts to ten per cent., and the increased value of the castings because of their accuracy.
