This bibliography covers not only the 589 case histories of the book, but it goes beyond this, especially in the presentation of references for 1917, 1918, and even 1919. Owing to the time when our country entered the war, American references are, in the main, of later date than the case histories. They will be found none the less of value to the student of neuropsychiatric problems.

The references in the bibliography number in all more than two thousand, distributed so far as nationalities are concerned about as given below, although some mistakes may have crept into this enumeration for various reasons, like the publication of the same articles in the journals of different countries. The list of references includes French, 895; British (English and Colonial), 396; Italian, 77; Russian, 100; American, 253; Spanish, 5; Dutch, 5; Scandinavian, 5; and Austrian and German, 476. It will be seen, therefore, that the bibliography covers in number nearly four times the collected case studies, most of these records being from reports made during the first three years of the war. The author has wisely made an effort to bring the bibliographic work up to and partially including 1919.

The manner in which the French neurologists and alienists continued their work during the strenuous days of the terrible conflict is worthy of all praise. The labors of the Society of Neurology of Paris never flagged, its contributions in current medical journals having become familiar to neurologists who have followed closely the trend of medical events during the war. Cases and subjects were also frequently presented and discussed at the neurological centers connected with the French and allied armies in France.

It may be almost invidious to specify names, the work done by many was of so much interest and value. Dejerine in the early days of the war, before his untimely sickness and death, contributed his part. Marie from the beginning to the end of the conflict continued to make the neurological world his debtor. The name of Babinski stands out in striking relief. Other names frequently appearing among the French contributors are those of Froment, Clovis Vincent, Roussy and Lhermitte, Léri, Guillain, Souques, Laignel-Lavastine, Courbon, Grasset, Claude, Barre, Benisty, Foix, Chavigny, Charpentier, Meige, Thomas, and Sollier.

For a work of this character not only as complete a bibliography as possible, but a thorough [index] is absolutely necessary, and this has been supplied. The author has not made the index too full, but with enough cross-references to enable those in all lines of medical work interested to cull out the cases and comments which most concern them.

My prologue finished, I step aside for the play and the player, with the recommendation to the reader that he give close heed to the performance—to the recital of the cases, the comments thereon, and the general discussion of subjects—knowing that such attention will be fully rewarded, for in this wonderful collection of Dr. Southard is to be seen an epitome of war neurology not elsewhere to be found.
