. Carnegie Institution of Washington publication. . THE COMPRESSIBILITIES OF THE MORE IMPORTANT SOLID ELEMENTS, AND THEIR PERIODIC RELATIONS. INTRODUCTION. In continuing the research upon compressibilities, it was desired to obtain a series of results from many of the more important elements, in order to discover their relation to one another, and to obtain as much light as possible upon the internal structure of solids in general. Accordingly, magnesium, calcium, zinc, cadmium, copper, silver, gold, palladium, plati- num, tin, lead, thallium, aluminum, iron, manganese, nickel, chromium, molybdenum, arsenic, antimony, and bismuth were all studied, and the interesting results obtained from this study are detailed below. The method of investigation was essentially similar to that already detailed in the preceding papers upon the compressibilities of the alkaline metals and the non-metals. Because of the less violent chemical nature of most of the heavier elements, the new problem was simpler than in the case of the alkaline metals, but because, on the other hand, their com- pressibilities for the most part are extremely small (often less than 1 per cent of the compressibility of water), great accuracy was needed in the conduct of the experiments. The method of procedure was in this case, as before, the following. In the first place, the amount of mercury needed in a suitably, arranged glass jacket for precisely attaining electrical contact with a very finely pointed platinum wire was determined at various pressures. The metal under examination was then immersed in the mercury and a similar series of experiments was once more conducted. Because nearly all of these metals had a compressibility less than that of mercury, less additional mercury would have been needed for a given pressure when the metal was present than when it was not present, except for the fact that in order to protect the metal, some other liquid besides mercury was also put into the jacket and compre
