The Theory of Environment by Armin Hajman Koller

I gratefully acknowledge my indebtedness to Professor Martin Schütze of the University of Chicago for the suggestion, made in 1907, to find out what Herder’s idea of milieu is; to my friend and former colleague at the University of Illinois, Dr. Charles C. Adams (now Assistant Professor of Ecology at Syracuse University) for references given me at my request (but he is in no wise to be held responsible for the bringing in of these references); and to my good friend and colleague, Professor John Driscoll Fitz-Gerald of the University of Illinois for a number of helpful suggestions given when reading the manuscript and for assisting with the reading of the galley proof.
