Dove right in by preparing
insect material for freeze drying
and starting the system. After dinner
with Paul returns to the lab,
connected frozen insects to the
vacuum system, then spent the
rest of the evening plucking and
cutting up birds for fat extraction -
not exactly an exciting pastime.
Finished in time to drive Paul to
the airport in the jeep which the
Institute provided for my use. Returned
to new (and much cheaper) room in
Hess Hall - an old dormitory on
"lower campus".
26 August
College, Alaska
Spent the day working with
the calorimeter (a Parr Oxygen
Bomb Calorimeter) to learn the
technique and experiment with
aculturation of samples with the
standard - benzoic acid. It worked
well using the Ptarmigan excrement
they has available.
Weighed my dried (oven dried,
that is) insects and found every
weight greater than Holmes'.
