Subject: 103'rd update on fly longevity experiments

    This is the 103'rd update of my fly longevity experiments. Average
temperature was 23.8 C during this run. Estimated maximal longevity using
the formula (363 - T*11.2) is 96 days.
    Here I test raw vegetable extracts by blending with water, and then
screening out the roughage. The extracts are then used in place of water
to hydrate the fly food powder.
    None of the vegetables offered any significant advantage on average
survival, and green cabbage at a high dose appeared to be toxic. Maximum
longevity was slightly improved by savoy cabbage.
