Subject: 204'th update on fly longevity experiments

     This is the 204'th update of my fly longevity experiments. Average
 temperature was 26.6 C during this run. Estimated maximal longevity using
 the formula (363 - T*11.2) is 65 days.
     B.R. donated a small amount of dilantin and piracetam for the current
 run. Control longevity was very poor in this run. Dilantin showed a
 strong dose dependant toxicity, but with a suggestion of a possible small
 benefit at the lowest dosage. Low doses of dilantin are being further
 investigated in run #216.
