VARIATIONS.
A. Declination.

The declination was observed from December 24, 1856, to January 19, 1857
(needle B5 being suspended in the vibrating apparatus, which could also be used
for declination). The units of scale readings are x/w of minutes of arc.

Increasing numbers correspond to an easterly motion of the declination.
