    This is the 83'rd update of my fly longevity experiments. Average
temperature was 20.5 C during this run. Here I continue testing beverages
from the local Chinatown.
    The maximum longevity of the control bottles was very good this time.
At 88 days, this is only a little short of equaling the record 93 days for
control maximum longevity, which was obtained in run #39. The low
temperature for this run, plus the use of a relatively new breeding bottle
may account the present good results.
    At 106 days, the maximum longevity of flies fed full strength white
gourd juice was also only a little short of the previous record of 118
days held by freeze concentrated Elderberry Nectar in run #36. This also
compared well with other juices in the present run, with only starfruit
juice showing nearly comparible longevity.
