Summary:
Miocene glacial period a remarkable discovery; if it is true, enlargement of Tertiary period necessary.
Received German monograph on Chilean Carabi that does not answer where isolated species came from.
HWB finds genital modifications of Chrysomela strong support for the theory.
Thanks for copy of Orchids.
