FORE:The means of supporting cores must be devised, or at least understood, by pattern-makers; these supports consist of 'prints' and 'anchors.' Prints are extensions of the cores, which project through the casting and extend into the sides of the mould, to be held by the sand or by the flask. The prints of cores have duplicates on the patterns, called core prints, which are, or should be, of a different colour from the patterns, so as to distinguish one from the other. The amount of surface required to support cores is dependent upon their weight, or rather upon their cubic contents, because the weight of a core is but a trifling matter [96] compared to its floating force when surrounded by melted metal. An apprentice in studying devices for supporting cores must remember that the main force required is to hold them down, and not to bear their weight. The floating force of a core is as the difference between its weight and that of a solid of metal of the same sizea matter moulders often forget to consider. It is often impossible, from the nature of castings, to have prints large enough to support the cores, and it is then effected by anchors, pieces of iron that stand like braces between the cores and the flasks or pieces of iron imbedded in the sand to receive the strain of the anchors.The woman was smiling now quite freely. All traces of passion and anxiety were gone. She knew the end had come, and she was prepared to accept it without complaint. Prout looked a little awkward as he bowed.

THREE:Spinoza gathered up all the threads of speculation thus made ready for his grasp, when he defined God as a substance consisting of infinite attributes, each of which expresses his infinite and eternal essence; subsequently adding that the essence here spoken of is Power, and that two of the infinite attributes are Extension and Thought, whereof the particular things known to us are modes. Platonism had decomposed the world into two ideal principles, and had re-created it by combining them over again in various proportions, but they were not entirely reabsorbed and worked up into the concrete reality which resulted from their union; they were, so to speak, knotted together, but the ends continued to hang loose. Above and below the finite sphere of existence there remained as an unemployed surplus the infinite causal energy of the One and the infinite passive potentiality of Matter. Spinoza combined and identified the two opposing elements in the notion of a single substance as infinite in actuality as they had been in power. He thus gave its highest metaphysical expression406 to that common tendency which we traced through the prospects opened out by the Copernican astronomy, the revival of Atomism, the dynamical psychology of Hobbes, and the illimitable passion of the Renaissance, while, at the same time, preserving the unity of Platos idealism, and even making it more concentrated than before.

THREE:V."Of course I was. Leon and myself had come to an understanding. He was going abroad after he had sent you the money. At great risk to myself I passed between here and the Corner House. I had to disguise myself. And when everything was ready Leon got at the brandy bottle again. For some nights he had not slept. When I got to the Corner House late that night Leon was practically dead. Ah, better for me if I had left him to die."
