[2] Some little-known but delightful observations in the prehistory of electromagnetism are described in a letter written by G. W. SCHILLING from London to the Berlin Academy on July 8, 1769, published as "Sur les phénomènes de l'Anguleil Tremblante" [_Nouveaux Mémoires de l'Académie Royale des Sciences et Belles-Lettres_, 1770 (Berlin, 1772), pp. 68-74], translated to French from the original German. The letter recounts a multitude of experiments with various electric eels. The two observations of electromagnetic interest are that a piece of iron held by the hand in the eel's tank could be felt quivering even when the fish was stationary several inches away, and a compass needle showed a deflection, both in the water near the fish, and outside the tank, also with the fish stationary.

The word "galvanometer" had been used much earlier by BISCHOF, "On Galvanism and its Medical Applications," _The Medical and Physical Journal_ (1802), vol 7, p. 529, for a form of goldleaf electroscope shown here in figure 2, but this use of the word does not seem to have been adopted by others.

A similar attitude was expressed in the same year by CHRISTIE, _Philosophical Transactions of the Royal Society of London_ (1833), vol. 123, p. 96: "I adopt the word current as a convenient mode of expression, ... but I would not be considered as adopting any theoretical views on the subject...."
