Strona 63 - My strong impression is that the surface of the iron is oxidised, or that the superficial particles of the metal are in such relation to the oxygen of the electrolyte as to be equivalent to an oxidation; and that having thus their affinity for oxygen satisfied, and not being dissolved by the acid under the circumstances, there is no renewal of the metallic surface, no reiteration of the attraction of successive particles of the iron on the elements of successive portions of the electrolyte, and therefore...
Strona 161 - ... serves to correlate some properties of metals which at first sight would appear to bear no relation to each other; it leads, namely, to the fact that there is a parallelism between all the elastic properties of metals for which quantitative measurements have been made and the pressure — assumed to act on the solid phase, but not, or not to the same extent, on the liquid phase — which is required to lower the melting-point to ordinary temperature. This pressure is a function of the melting-point,...

Strona 123 - Since the specific gravity of a substance is the weight of a unit volume of the substance compared, the susceptibilities may be converted into mass values by dividing the volume values...
Strona 195 - About 5CIU' of water was added, and then from 2cm> to 5cm3 of sulphuric acid. The water and excess of sulphuric acid were evaporated off by directing a small flame from the blast lamp nearly vertically downward upon the liquid. The evaporation required about fifteen minutes. The results obtained upon weighing the crucible and barium sulphate were satisfactory in three cases out of five, but in the other two cases there was loss. To prevent this a cone of fine platinum gauze was fitted into the mouth...
