	Did a similar thing with a sheep muscle. With the large cross
sectional area I just kept the muscle height fairly thin. Although ice
crystal damage was evident in a number of blocks it didn't prevent good
fibre typing. Didn't have any photometric measuring to perform so was quite
happy with wee patches of ice damage.
