mean the very highest possible developments. Well, I tried a series of experiments upon this point. I found that in liquids, and in compounds, the force had a disintegrating effect. The well-known experiment of the electrolysis of water will, of course, occur to you. But I found that in the case of elemental solids the effect was a remarkable one. The element slowly decreased in weight, without perceptibly altering in composition. I hope that I make myself clear to you?" "I follow you entirely," said Robert, deeply interested in his companion's narrative. "I tried upon several elements, and always with the same result. In every case an hour's current would produce a perceptible loss of weight. My theory at that stage was that there was a loosening of the molecules caused by the electric fluid, and that a certain number of these molecules were shed off like an impalpable dust, all round the lump of earth or of metal, which remained, of course, the lighter by their loss. I had entirely accepted this theory, when a very remarkable chance led me to completely alter my opinions. "I had one Saturday night fastened a bar of bismuth in a clamp, and had attached it on either side to an electric wire, in order to observe what effect the current would have upon it. I had been testing each metal in turn, exposing them to the influence for from one to two hours. I had just got everything in position, and had completed my connection, when I received a telegram to say that John Stillingfleet, an old chemist in London with whom I had been on terms of intimacy, was dangerously ill, and had expressed a wish to see me. The last train was due to leave in twenty minutes, and I lived a good mile from the station, I thrust a few things into a bag, locked my laboratory, and ran as hard as I could to catch it. "It was not until I was in London that it suddenly occurred to me that I had neglected to shut off the current, and that it would continue to pass through the bar of bismuth until the batteries were exhausted. The fact, however, seemed to be of small importance, and I dismissed it from my mind. I was detained in London until the Tuesday night, and it was Wednesday morning before I got back to my work. As I unlocked the laboratory door my mind reverted to the uncompleted experiment, and it struck me that in all probability my piece of bismuth would have been entirely disintegrated and reduced to its primitive molecules. I was utte
