I should have mentioned you in my last Cryonet message, and this one is to
repair the lack. You have, in the midst of other comments, answered some
of my questions about vitrification, particularly the range of temperatures
within which cracking does not occur. 

At one time there were several long discussions on Cryonet as to ways by
which we could set up passive systems which would keep temperatures within
the required range. This discussion basically petered out. However if the
temperature of vitrification remains higher than that of LN2, depending on
refrigerators may not be a good long term solution for cryonics. Perhaps 
that discussion should be reawakened.

(And cryonics includes suspended animation here, so long as the patient
was in suspended animation for a condition not presently curable for which
no one could predict the time at which a cure might arrive).

			Best, thanks again, and long long life,
