Subject: 154'th update on fly longevity experiments

     This is the 154'th update of my fly longevity experiments. Average
 temperature was 27.4 C during this run. Estimated maximal longevity using
 the formula (363 - T*11.2) is 56 days.
     Obscure produce is again tested in this run. After starting the last
 run I read that raw fiddleheads are toxic, so this run tests them again,
 but in a cooked condition. An earlier run had tested red cabbage with
 disappointing results. Here I try a hot water extract to see if this
 would make a difference.
     Mold made another unwelcome appearance in this run. Fortunately
 shortly after I started this run, I had at last discovered that one batch
 of my fly food was in fact unusable. Switching to another bag solved this
 problem.
     No positive results were noted in this run.
