Summary
It is shown that differences in the asymmetry (optical impurities) of an added compound may influence considerably the crystallisation pattern of cupric chloride when crystallised under constant conditions on a glass plate. The high amplification of a purely formal difference in asymmetry calls for a specific information mechanism, one crystallographic possibility of which is discussed. This shows an approach to the problem of recognizing optical impurities in mixtures. The results are discussed in connection with the spontaneous racemisation in biochemical systems and may contribute to the understanding of the ‘diagnostic biocrystallisation’ of copper chloride in cases of cancer
