FOOTNOTES:
[5]Professor Huxley's “Physiography,” published by D. Appleton & Co., New York, is an excellent text-book for the study he here recommends. It has been drawn upon for two chapters of the first volume of “Masterpieces of Science.” Equally to be recommended are “Physical Geography” and “Elementary Physical Geography,” by Prof. W. M. Davis, of Harvard University, published by Ginn & Co., Boston.
