Page 256 - ... to be not sensibly magnetic by our test; but it always acquired a sensible magnetism when charged with hydrogen. It appears to follow that hydrogenium is magnetic, a property which is confined to metals and their compounds. This magnetism is not perceptible in hydrogen gas, which was placed both by Faraday and by .ME Becquerel at the bottom of the list of diamagnetic substances.

Page 248 - IT has often been maintained on chemical grounds that hydrogen gas is the vapour of a highly volatile metal. The idea forces itself upon the mind that palladium with its occluded hydrogen is simply an alloy of this volatile metal in which the volatility of the one element is restrained by its union with the other, and which owes its metallic aspect equally to both constituents.
Page 258 - ... of hydrogenium, and that the density of the latter is about 2, a little higher than magnesium, to which hydrogenium may be supposed to bear some analogy ; that hydrogenium has a certain amount of tenacity, and possesses the electrical conductivity of a metal ; and, finally, that hydrogenium takes its place among magnetic metals. The latter fact may have its bearing upon the appearance of hydrogenium in meteoric iron, in association with certain other magnetic elements.
Page 323 - On passing a stream of induction sparks through the gas standing over liquefied sulphurous anhydride in a strong tube, at the ordinary temperature, when a pressure of about three atmospheres was exerted by the gas, a very brilliant light was obtained. A stream of induction sparks was passed through air confined in a glass tube connected with a condensing syringe, and the pressure of the air...
