Notwithstanding that every effort has been made to conveniently and satisfactorily group the thousands of cases contained in the book (a labor of no small proportions in itself), a complete general index is a practical necessity for the full success of what is essentially a reference-volume, and consequently one has been added, in which may be found not only the subjects under consideration and numerous cross-references, but also the names of the authors of the most important reports. A table of contents follows this preface. We assume the responsibility for innovations in orthography, certain abbreviations, and the occasional substitution of figures for large numerals, fractions, and decimals, made necessary by limited space, and in some cases to more lucidly show tables and statistics. From the variety of the reports, uniformity of nomenclature and numeration is almost impossible. As we contemplate constantly increasing our data, we shall be glad to receive information of any unpublished anomalous or curious cases, either of the past or in the future. For many courtesies most generously extended in aiding our research-work we wish, among others, to acknowledge our especial gratitude and indebtedness to the officers and assistants of the Surgeon-General's Library at Washington, D.C., the Library of the Royal College of Surgeons of London, the Library of the British Museum, the Library of the British Medical Association, the Bibliotheque de Faculte de Medecine de Paris, the Bibliotheque Nationale, and the Library of the College of Physicians of Philadelphia.
