this is obscured by having a piece of plain paper pasted over it. Presumably
the inner forme of the Wrst gathering was printed oV before the decision was
made to issue a few copies of the Gassendi alone. The titlepage was altered,
but it was by now too late to alter the table of contents on the verso, so the
solution was to cover it up. The text ends ‘Finis’ on p. 160.

The Wrst report of Gauss’s important geomagnetic work presenting a logical
set of units of measurement for magnetic phenomena. This was the Wrst systematic
use of absolute units to measure non­mechanical qualities and the
unit of magnetic Xux density was later called the gauss in honour of this work.
Gauss worked on geomagnetism between 1831 and 1837 in collaboration with
Wilhelm Weber (1804–1891), Gauss leading the theoretical side and Weber
the experimental.
