It was ob- cadmium with two equivalents cach of these served in Berlin that those parts of a bronze three other metals, at 1557°, which is also a bronze three other metals, at 1554°, which is also statue which were much handled by the the fusing point of an alloy of 1 part each of all public retained a good surface, and this led to the four metals. Dr. von Hauer máde these this led to the four metals. Dr. von Hauer made these the conclusion that fat had something to do alloys by fusing their ingredients in a covered with it. An experiment was therefore tried porcelain crucible at the lowest practicable for some years with four bronzés. One, says temperature. They all become pasty at lower our authority-Chambers' Journal -was coat- temperatures than those given above; the ed every day with oil, and wiped with a cloth; temperatures quoted are those at which the another was washed every day with water; alloys are perfectly fluid. It should be added the third was similarly washed, but was that, unfortunately, all these alloys very oiled twice a year; and the fourth was left untouched. The first looked beautifully; the third, which had been oiled twice a year , was passable; the second looked dead; and the fourth was dull and black.
