As time wore on, this “preparedness” ideal gave place to the ideal of a collection of cases to serve as a source-book for reconstructionists dealing with neuroses and psychoses. Shortage of medical staff and delays incidental to the influenza epidemic held the book back still further, and, as meantime Brown and Williams had served the immediate need with their _Neuropsychiatry and the War_, it was determined to make the compilation the beginning of a case-history book on the neuropsychiatry of the war, following in part the traditions of various case-books in law and medicine. With the conclusion of the armistice, there is by no means an end of these problems. Peace-practice in neuropsychiatry is bound to undergo great changes and improvements, if only from the influx into the peace-community of many more trained neuropsychiatrists than were ever before available. This is particularly true in the American community by reason of the many good men specially trained in camp and hospital neuropsychiatry, both at home and in the A. E. F., through the enlightened policy of our army in establishing special divisions of the Surgeon-General’s Office dealing separately with those problems. Though a book primarily for physicians, some of its material has interest for _line-officers_, who may see how much “criming” is matter for medical experts, by running through the boxed headings (especially of Sections A and B) and reading the simulation cases. As Chavigny remarks, “shooting madmen neither restrains crime nor sets a good example.” But parts of the book look ahead to _Reconstruction_. Surely occupation-workers, vocationalists, war risk insurance experts, and in fact all reconstructionists, medical and lay, must find much to their advantage in the data of Section D (Treatment and Results). Had time permitted, the whole old story of “Railway Spine”--Shell-shock’s congener--might have been covered in a series of cases from last century’s literature, together with others illustrating the effects of suggestion and psychotherapy; but this must be a post-bellum task. The compiler, who has personally dictated (and as a rule redictated and twice condensed) all the cases from the originals (or in a few instances, _e.g._, Russian, from translations), hopes he has not added anything new to the accounts. The cases are drawn from the literature of the belligerents, 1914-1917, English, French, Italian, Russian, and--so far as available here--German and Austrian.
