My thanks are due to General Horace Porter and the Honorable Charlemagne Tower, LL.D., ambassadors of the United States to France and Russia respectively, for investigations in answers to inquiries, and for suggestions; to Dr. Talcott Williams, of Philadelphia, for valuable suggestions as to sources of possible information; to the Rev. Dr. William Elliot Griffis, of Ithaca, New York, for much interesting matter connected with the Baron van der Capellen, for unpublished manuSCRJPT notes on North Holland, the Helder, and the Texel, and for the rare copy of the old Dutch song, "Hir komt Pauwel Jones aan," which appears in the appendix; to Lieutenant-General O. V. Stubendorff, Chief of the Topographical Section of the Imperial Russian General Staff, and to Major-General E. Sarantchof, of the Russian army, for maps, reports, and other data concerning the campaign on the Dnieper-Liman, not accessible in any American books; to Mr. Charles T. Harbeck, of New York, for generous permission to make use of rare books and pamphlets relating to Paul Jones in his valuable collection of Americana; to Messrs. W. M. Cumming and Junius Davis, of Wilmington, N. C., and Mrs. A. I. Robertson, of Columbia, S. C., for information concerning the assumption of the name of Jones by John Paul, not hitherto published in book form; to Mr. E. G. McCollin and the Misses Mabel S. Meredith, Edith Lanigan, and Bertha T. Rivailles for much important work in translation; and to Miss Isabel Paris for invaluable assistance in transcribing the manuSCRJPT.

Lest any of the above should be involved in possible criticisms which may be made of the book, I beg to close this preface with the assurance that for everything which follows I alone am responsible.
