    If you have a sharp look you will find like me, that it cannot be a tray of mercury which would freeze at -38°C but a mirror with two bubble levels filled with some kind of alcohol e.g. diethylether which freezes at -116^C

    On top of the box is an artificial horizon not a chronometer.
    The explanation in the text is:
    "Helmer Hanssen (right) is bending over the artificial horizon, which is a tray of mercury."
    Why his is doing that - bending over the tray - I don't know.
