MAGNETISING WATER.

MAGNETISING WATER.

There are three fountains in Indiana that magnetise needles, scissors, knife blades, and other steel objects immersed in their waters. The first is a spring at Cartersburg; the second is a driven well at Lebanon; and the third is a driven well at Fort Wayne. The waters contain a large proportion of carbonic acid, which is disengaged on exposure to the air. As this gas escapes, a heavy precipitate of oxide of iron forms, and when all the gas has disappeared no more magnetism manifests itself. The waters deviate the compass needle, and that of one of the wells used in locomotive boilers has been found to be corrosive and rapidly injurious to those receptacles. When allowed to remain in a reservoir for some time, however, this property of it disappears and it is noncorrosive, as other waters. A scientific publication speaks of the authentication of magnetic properties in these waters as important from a scientific point of view, though their ascertained utilities so far amount to very little, and there is little prospect of their increase.
