Abstract
It seems to me that Prof. Japp has not understood the purpose of my reference to “the formation of hematite nodules and flints in chalk.” I instanced this simply as showing that segregation slowly takes place notwithstanding great restraints, such as that which a chalk-stratum offers; and my argument was that if segregations of hematite and flint take place in long periods notwithstanding such great restraints, it may reasonably be inferred that segregations of such slightly-different molecules as those of dextro- and laevo-protein would gradually take place under the slight restraints offered by a colloidal substance like protein. Unless due time is given, nothing can be expected.
