Studien ueber Hautelektricität und Hautmagnetismus des Menschen

Abstract

THE author takes a pocket-compass, about the size of a lady's watch, with metal case and watch-glass top, and having placed it on a level surface lightly rubs the glass with the tip of his finger. The needle is immediately deflected from the magnetic meridian, remaining so for a minute or more, and then returning to its original position. That magnetism has nothing; to do with it is shown by the fact that the same phenomenon occurs when for the magnet there is substituted a needle of nickel, platinum, zinc, bismuth, or ivory, although the absence in such cases of a directive force makes it more difficult to observe. Static charges, apparently much stronger, are without effect. Some people can influence the needle much more than others, and the author's power is not always equally strong.
