Andrew Murray’s article plays into CD’s hands through sheer ignorance.

JDH is on Royal Society Council.

Summary

Does not fact that characters important in systematics are often of no use, corroborate CD’s view that such characters, if not detrimental, may persist ad infinitum?

Social news.

JDH’s objections to CD’s idea of how Greenland was repopulated. Temperate Greenland has as Arctic a flora as Arctic Greenland – a fact of astounding force. Why should certain Scandinavian species be absent? Migration by sea-currents can no more account for the present distribution in Greenland than can special creation.

Summary

JDH battling with Lyell over treatment of species question in Antiquity of man. Distressed by Lyell’s raising false priority issue between JDH and CD. Falconer involved in a priority squabble.
