I would be very surprised if there is anything in honey that acts as
a fixative. Remember that honey is evolved to be food for growing bee
larvae, not exactly something compatible with fixation.
I do find it easy to believe that honey acts as a preservative,
simply because its high sugar content makes honey a strong
dehydrating agent. This will perserve tissue and prevent bacterial
and fungal growth. It would be interesting to do a similar study on
salt-preserved tissues. I suspect the results would be similar,
although the morphology would be uglier in the salt-preseved tissue
because salt's strong osmotic effects.
