Excerpt from Psychical Phenomena and the War For material utilized in Part I, I wish especially to acknowledge my indebtedness to M. Lebon's book, The Psychology of the Great War, and to Dr. George W. Crile's Mechanistic Conception of War and Peace. The bulk of the psychological material, relating to the mind of the combatant in action, is taken from my own article on The Mind of the Soldier, first published in the Forum, January, 1916, and reprinted here, by the editor's kind permission, with considerable addi tions. The chapter dealing with the psychology of the soldier in action is (naturally) based almost entirely upon Observations on the franco-british front; and but little reference to the psychology of the American soldier is as yet possible. Doubtless many psycho logical Observations of great value will be forthcom ing, when U. S. Soldiers get into action on a vast scale.
