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
