Subject: 213'th update on fly longevity experiments

     This is the 213'th update of my fly longevity experiments. Average
 temperature was 23.7 C during this run. Estimated maximal longevity using
 the formula (363 - T*11.2) is 98 days.
     Ginkgo biloba at a 20 mg dosage increased survival in run #37. This
 run retests ginkgo at a variety of dosages.
     Blue corn additions rendered the surface of the fly food somewhat
 wet. I had noticed that when this occurred in the past that survivals
 tended to be reduced, probably through increased bacterial growth.
 Nonetheless maximum survival was increased, although admitedly control
 survival was rather poor.
     Once again the 20 mg dosage of ginkgo proved to be advantageous,
 while higher dosages proved to be toxic. Of great interest, a lower 10 mg
 dose offered a better result.
     Terminalia arjuna bested the control bottles as well.
