In the following paper I desire to place on record the results of certain experiments which have lately engaged my attention. The facts established are, so far as I am aware, novel and in themselves interesting.
Many of the physical properties of hydrogenised palladium or hydrogenium have been carefully studied by Graham, Dewar, and others; but no one seems to have called attention to its thermoelectric peculiarities, or to have made a special study of its electrical resistance. These two inquiries form the subject of this paper. Throughout I shall use, for brevity's sake, the name Hydrogenium, which was applied by Graham to the fully-saturated form.

page 179 note * The signs are here changed so as to agree with Tait's theory, which connects the inclinations of the thermoelectric lines with the Thomson effects in the corresponding metals. I shall always speak of iron as lying above lead, and palladium as below lead, on the thermoelectric diagram.
