III. On electrical conductivity and electrolysis in chemical compounds

In presenting this communication to the Royal Society I wish to state that it is only an abstract of a more extensive paper on the same subject which I hope to publish shortly, and which contains an account of experiments with nearly seventy substances, most of which were never used before for such an investigation. I tried also nearly all the liquefied gases, and a considerable time was spent in preparing them for this kind of research, that was often interrupted by fearful explosions. The invaluable opportunity which Mr. Warren De La Rue, F. R. S., granted me some time ago to try the same compounds with his very powerful battery, led to results which I hope the Society will not consider devoid of interest.
