Subject: CRYONICS clarify sheep

On the subject of others repeating Cryonics Institute's sheep head
experiments, a correction and comment.

In the printed procedures we mailed, we made a mistake about the cool-down
and warm-up times. We said 7 days to dry ice and another 7 days to liquid
nitrogen, which is what we do for humans. But with the sheep heads we
actually took 5 days to dry ice and 5 days to liquid nitrogen, then another
10 days to warm back up to room temperature.

It could also be important to note that we saw considerable individual
variation from one sheep head to another--variation in the difficulty and
quality of washout and perfusion. Therefore it will be useful to get as many
specimens as feasible, and by as many different investigators. At present it
looks like we will have Dr. Pichugin's group in the Ukraine (who have already
started), probably Alcor, and perhaps Dr. Soloviov's group in St. Petersburg.
