Removed box containing thermometers from the mizzen rigging to the floe and secured it to stanchion embedded in the ice.

The Liquid Compasses were taken out of the Binnacles and stored below :- it being noticed that the spirit contained in them was oozing out over the glasses.

The Yukon barometer during the 1917 voyage appears to be biased on the low side. The average reading is in the mid 29's and it is not unusual for it to drop below 29. Here is a good example - a reading of 28.33.

Weather, squally, driving rain, stiff southeasterly breezes.

I would expect more than a stiff breeze with that reading!

The following day, Oct 10, is clear and the pressure rises to 29.58
Oct. 11 it's back down to 28.37
Oct 12 up to 29.64
Oct 13  30.12
Oct 14 29.92
Oct 15 29.26
Oct 16 29.35
OCt 17 29.86

Jeannette - I don't know if this is of any use but on the 1st March 1880 entry in De long's journal (pages 273-4) he includes some comparisons of the mercurial and various spirit thermometers.
