VII. The Section of Periodicals is actually an excerpt from my " Cata-

logue of Scientific and Technical Periodicals, 1665 to 1882," (Smithsonian Miscellaneous Collections, vol. 29, Washington, 1885), enlarged by the ad- dition of serials published by Societies and brought down to date.
In each Section, excepting those of Biography and Periodicals, the titles are arranged alphabetically by authors, translations of each work fol- lowing the original in the alphabetical order of the English names of the languages. The order is the same as in the table on page xiii. This table must not, however, be regarded as indicating the relative number of chemical works in the given languages, since the facilities for collecting the information from different countries are very unequal.
In the Section of Biography the titles are placed under the names of the persons described, with cross-references from the authors ; in the Sec- tion of Periodicals the titles are arranged alphabetically by the first word, articles and " New " excepted, with cross-references from the editors.
Notes and comments, bibliographical and explanatory, have been oc- casionally introduced, especially in the Sections of History and of Alchemy, to aid students in conceiving the character of a book, or the status of the author.
The sources of the titles are, of course, general and special bibliogra- phies, and libraries (named below). For the principal bibliographies con- sulted see Section I
In several of the larger libraries the manuscript catalogues of chem- istry were transcribed with great care (Konigliche Bibliothek, Berlin ; Grossh. Bibliothek, Darmstadt) ; in others I had access to the shelves as well (British Museum, London ; Patent Office, London ; Universitats

Bibliothek, Strassburg ; and the Libraries in the United States of America).
In the preparation of this volume I have enjoyed the facilities offered by the following Libraries and Institutions, and I hereby express my hearty thanks to the respective Librarians and other Officers for their cour- tesies and for special privileges : British Museum, London ; Patent Office, London ; University Library, Cambridge ; Free Library, Birmingham ; Bibliotheque Nationale, Paris ; Bibliotheque de la Sorbonne, Paris ; Biblio- thequedu Jardin des Plantes,Paris; Bibliotheque du Conservatoire des Arts et Metiers, Paris ; Bibliotheque de la Soci^te chimique de Paris ; Biblio- theque Mazarin, Paris; K. Universitats- und Landes-Bibliothek, Strassburg; Grossh. Universitats Bibliothek, Heidelberg ; Grossh. Hof-Bibliothek, Darmstadt ; Konigliche Bibliothek, Berlin ; K. Universitats Bibliothek, Prag ; Bohmisch National Museum, Prag ; K. K. Hof Bibliothek, Wien; K. K. Universitats Bibliothek, Wien ; Bibliothek der K. K. technischen Hochschule, Wien ; K. Universitats Bibliothek, Budapest ; K. Akademie der Wissenschaften, Budapest ; K. K. Oeffentliche Landes- und Studien- Bibliothek, Salzburg ; Bibliothek des Carol Aug. Museum, Salzburg ; K. Hof- und Staats-Bibliothek, Miinchen : K. Oeffentliche Bibliothek, Stuttgart ; Library of the Surgeon-General's Office, United States Army, Washington ; Library of Congress, Washington ; Scientific Library of United States Patent Office, Washington ; Public Library, Boston ; Athenaeum, Boston ; Massachusetts Institute of Technology, Boston ; Harvard College Library, Cambridge ; Dartmouth College Library, Hanover, N. H ; Amherst College Library, Amherst, Mass.; Library of Columbia College, New York ; Astor Library, New York ; Library of the New York Academy of Sciences.
I am also under obligations to Prof. Charles F. Chandler, Ph.D., M D., LL.D., of Columbia College, New York, and to Prof. Rudolph A. Witthaus, M.D., of the Medical College of the University of the City of New York, for permission to catalogue their valuable private collections.
I am very greatly obliged to Dr. Alfred Tuckerman, of Newport, R. I., for voluntary assistance ; he made a preliminary examination of Poggen- dorff's Handworterbuch, as well as of Zuchold's and Ruprecht's Bibliotheca, copying many titles for this Bibliography with accuracy and fidelity.
I am also specially indebted to Prof. Bohuslav Brauner, of Prag, for
PREFACE. IX
revision of Bohemian titles of periodicals, and to John Fryer, LL.D., of Shanghai, for a list of treatises in Chinese.
To insure the greatest possible accuracy in the several languages I secured the aid of linguistic experts. The Rev, Prof. Samuel Hart, D.D., of Trinity College, Hartford, Conn., read the Greek and the Latin ; the Rev. Martin Osserwaarde, of New York, read the Dutch ; Mr. Axel Moth, of New York and Copenhagen, read the Danish, Norwegian, and Swedish ; Signor Cesare Poma, Vice-Consul of Italy, of New York City, read the Italian, Spanish, and Portuguese ; Mr. Louis Solyom, of the Library of Congress, Washington City, read the Hungarian, Russian, Polish, Bo- hemian and other Slavonic languages ; Mr. George H. Boehmer, of the Smithsonian Institution, assisted me in the French and the German. The proof-reading continued for twelve months, and matters were so arranged that each expert saw titles only in the language or group of languages which he engaged to read. To these gentlemen I am under great obliga- tions for their assiduity, promptness, and fidelity to my interests.
For the conception and contents of this bibliography I alone am responsible ; its publication has been made possible by the liberality of the Smithsonian Institution, to which I presented the manuscript compiled as a labor of love.
