 this all. These particles, commonly called electrons, if particles they can still be designated at all, were at first said to "carry" a charge of electricity. But it now seems that they are electricity itself. If this be true, we should seem to be on the point of bridging the void between what used to be called the eternal antithetics—matter and force: and whither this will lead us can only with the greatest caution be pre-imagined. In any case the consequences of this discovery, philosophical as well as scientific, are stupefying in the possibilities they open up to the thinker as well as to the man of practical science. At last science begins to join hands with philosophy. What will be the philosophy of a hundred years hence, imagination pales before the effort of attempting to conceive.

But the working out of the revelations promised by radiology belongs rather to this end of the century than to the other. During the interval there can be no doubt that electricity, already man's chief handmaid, will have increased and perhaps completed her services to the race. When, as I ventured to suggest in a former chapter, inexhaustible and cheap "current" is yielded to us by some method of utilising the electrical reciprocity of the hydrogen and oxygen gases derived from water, doubtless all machinery will be electrically driven, all transport electrically
