Did Edgeworth David do any writing in his later years?
In 1931 Edgeworth David published the Geological Map of the Commonwealth and the accompanying Explanatory Notes, designed to be part of his Geology of the Commonwealth of Australia.
Are there any other interesting aspects about this Edgeworth David article regarding his later years besides when he published the Geological Map of the Commonwealth?
Edgeworth David died in 1934 without being able to complete this work and was given a state funeral.

Question: What did he do to receive that honor?
