Subject: 153'rd update on fly longevity experiments

     This is the 153'rd update of my fly longevity experiments. Average
 temperature was 27.1 C during this run. Estimated maximal longevity
 using the formula (363 - T*11.2) is 59 days.
     Here I check out some obscure produce. Purple cauliflower looked
 like it was helping by the day 27 census, but rapidly reverted after
 this. Since an earlier test had found that ordinary cauliflower was of no
 value, it is tempting to suppose that it was the purple coloring that
 might be responsible for this temporary benefit. Of the other items,
 sunburst squash 5% looked slightly interesting, although this might have
 been a fluke.
