"While on the subject, I have to note the response I have received to my
offer (posted here and on sci.cryonics) to send anyone a free back issue
of CryoCare Report, containing an article by Mike Darwin including
electron micrographs showing differing degrees of damage to brains frozen
with two different cryoprotective protocols"

Electron micrograms are artifacts that may reflect the technicians experience
preparing tissue for the instrument. Until different very competent persons
have repeated the preparation of frozen brain tissue one would not know
whether the damage is due to freezing or the preparation of the tissue for the
microscope.
