l. 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...."

[13] Some prominent examples of this brevity of treatment are in E.
HOPPE, _Geschichte der Elektrizitaet_ (Leipzig, 1884); O. MAHR,
_Geschichtliche Einzeldarstellungen aus der Elektrotechnik_ (Berlin,
1941); R. S. WHIPPLE, "The Evolution of the Galvonometer," _Journal of
Scientific Instruments_ (1934), vol. 7, pp. 37-43; WILLIAM STURGEON,
_Scientific Researches_ (Bury, 1850); A. W. HUMPHREYS, "The Development
of the Conception and Measurement of Electric Current," _Annals of
Science_ (1937), vol. 2, pp. 164-178.

on page 319. The many experiments described in this paper added little
or nothing to contemporary appreciation of the multiplier as an
instrument.

[16] J. S. C. SCHWEIGGER, _Journal fuer Chemie und Physik_ (1821), vol.
31, pp. 1-18, 35-42. Pages 1-6 are the paper presented in Halle on
September 16, 1820; pages 7-18 are the paper presented in Halle on
November 4, 1820, and pages 35-42 are "a few additional words." The
preface to the whole volume is dated January 1, 1821. A somewhat earlier
public announcement referring to Schweigger's discovery appeared in the
_Allgemeine Literatur-Zeitung_ (November 1820), no. 296, cols. 622-624,
but this was lacking in detail and seems not to have been noticed by any
scientists.

[17] P. ERMAN, _Umrisse zu den physischen Verhaeltnissen des von Herrn
Prof. Oersted entdeckten elektro-chemischen Magnetismus_ (Berlin, 1821).
Hoppe (footnote 13) states that Erman's book was published in May;
however, it is referred to in a letter dated April 3, 1821, by RASCHIG,
_Annalen der Physik_ (1821), vol. 67, pp. 427-436.

pages 429-430 of same volume. The footnote accompanies the article by
Raschig mentioned in footnote 17.
