Den 13de Juni tog Prof. Mohn følgende
Observationer til Bestemmelse af Deklinationen, paa samme Tid
som jeg svang Skibet for at bestemme Compassernes
Deviation. Stativet med Theodoliten rykkedes 0.75 .Meter,
mod Sydsydost fra den forrige Plads. Herved bliver
Azimut af Poldetind fra den nye Plads 0/1 mindre, eller
N 48° 7/5 E.
Magnetometret opstilledes paa sin Plads og der
gjordes følgende Observationer, med Instrumentets egen
Kikkert. for at bestemme Magnet-Axens Collimation.
On the 13th of June. Professor Mohn took the
following observations to determine the declination, whilst I
swung the ship for deviation of compass. The theodolite
and stand was now moved 0.75 metre south-south-east from
its former position. Taken from this point, the azimuth of
Poldetind will be 0/1 less, or N 48,J 7/5 E.
After mounting the magnetometer, he took the
following observations, with the telescope of the instrument,
to determine the collimation of the axis of the magnet: —
The horizontal angle between Poldetind and the gable
of a house, was measured at the same time with the
theodolite, and found to be 130° 50/1. Hence, the azimuth
of the gable = N 178° 57/7 E, or S 1° 2/3 E.
