FORE:The expense of forming pattern-moulds may be considered as divided between the foundry and pattern-shop. What a pattern-maker saves a moulder may lose, and what a pattern-maker spends a moulder may save; in other words, there is a point beyond which saving expense in patterns is balanced by extra labour and waste in moulding��a fact that is not generally realised because of inaccurate records of both pattern and foundry work. What is lost or saved by judicious or careless management in the matter of patterns and moulding can only be known to those who are well skilled in both moulding and pattern-making. A moulder may cut all the fillets in a mould with a trowel; he may stop off, fill [94] up, and print in, to save pattern-work, but it is only expedient to do so when it costs very much less than to prepare proper patterns, because patching and cutting in moulds seldom improves them.Not only oratory and literature, but philosophy and science were cultivated with renewed vigour. The line between philosophy and sophisticism was not, indeed, very distinctly drawn. Epict��tus severely censures the moral teachers of his time for ornamenting their lectures with claptrap rhetoric about the battle of Thermopylae or flowery descriptions of Pan and the Nymphs.406 And the professed declaimers similarly drew on a store of philosophical commonplaces. This sort of popular treatment led to the cultivation of ethics and theology in preference to logic and metaphysics, and to an eclectic blending of the chief systems with one another. A severer method was inculcated in the schools of Athens, especially after the endowment of their professors by Marcus Aurelius; but, in practice, this came to mean what it means in modern universities, the substitution of philology for independent enquiry. The question was not so much what is true as what did Plato or Aristotle really think. Alexandrian science showed something of the same learned and traditional character in the works of Ptolemy; but the great name of Galen marks a real progress in physiology, as well as a return to the principles of Hippocrates.
