Fig. 1.—Cast Metal 15 Diams. finitely. Its non-corrodibility has been de-monstrated by a 56-day test with 40 de-grees of sulphuric acid, which producedno loss whatever. The metal may be as easily drawn andcast as it is rolled and amonsr the pos-sible uses of the hot-rolled, appear suchas roofing, ventilators, smoke stacks, shipplates, etc., the cold rolled sheets beingused in making hospital equipment,watch eases, knives, forks, spoons, andsimilar articles. For castings which are subject to se-vere strain or shock, it is admirablysuited, as has been demonstrated by itsuse in making propeller wheels, castsolid hub and arms. When drawn into wire or rolled into. ers of the same thickness of metal maybe subjected to a much greater hydraulicpressure with safety. It is possible alsofor it to be drawn into shapes such asboiler heads and pantry sinks. An important feature of the metal isthat having so large a constituent ofnickel it can be polished to have thesame bright surface found in nickelplated articles without the expense ofnickel plating. This adapts it admirablyto boiler and sink construction, as well asto bar fixtures, and, being a harder met-al, it is capable of standing rougher us-age without showing dents, and promisesto wear longer. Being of the same ma-terial all the way through it can be keptpolished as long as it lasts. Stronger than Steel. The accompanying illustrations are ex-act size reproductions of micro-photo-graphs of the cross section of pieces ofcast and rolled Monel metal. Figs. 1 and2 are of the same cross-section, but inFig. 1 the light is directly on the sectio
