By the way, just as I found John Milton had said things that fitted neurosyphilis, so also Dante is observed in the chosen mottoes to have had inklings even of Shell-shock. To the _Inferno_ it was natural to turn for fitting mottoes (Carlyle’s renderings mainly used). The pages might have been strewn with them. A glint of too great optimism might seem to shine--in the pre-Epicrisis motto--from the lance of Achilles with its “sad yet healing gift;” but out of Shell-shock Man may get to know his own mind a little better, how under stress and strain the mind lags, blocks, twists, shrinks, and even splits, but on the whole is afterwards made good again. E. E. SOUTHARD. WASHINGTON, _November, 1918_. INTRODUCTION The duties of an introducer, whether of a platform speaker to an audience, or of a writer to his anticipated readers, are not always clearly defined. It has been sometimes said that the critic or reviewer may meet with better success if he has not acquainted himself too thoroughly with the contents of the book about which he writes, as in that case he will have a larger opportunity to indulge his imagination, but a critique thus produced may have the disadvantage of possible shortcoming or unfairness. In the case of this volume, however, I have felt it worth while to acquaint myself with its contents, no light task when one is confronted with a thousand pages. The great war just closing has done much to enlighten us as to the causes, nature, outcome, and treatment of injuries and diseases to which its victims have been subjected. The object of this book is to present both the data and the principles involved in certain neuropsychiatry problems of the war. These are presented in a wealth of detail through an extraordinary series of case records (589 in all) drawn from current medical literature, during the first three years of the conflict. Case reporting is here seen at its best, and the experiences recorded are largely allowed to speak for themselves, although comments are not wanting and are often illuminating.
