Joseph Henry
MEMOIR JOSEPH HENRY. SIMON NEWCOMB. BEAD BEFORE THE NATIONAL ACADEMY OP SCIENCES, APRIL 21, 1880. (1) BIOGRAPHICAL MEMOIR OF JOSEPH HENRY. In presenting to the Academy the following notice of its late lamented President the writer feels that an apology is due for the imperfect manner in which he has been obliged to perform the duty assigned him. The very richness of the material has been a source of embarrassment. Few have any conception of the breadth of the field occupied by Professor Henry's researches, or of the number of scientific enterprises of which he was either the originator or the effective supporter. What, under the cir- cumstances, could be said within a brief space to show what the world owes to him has already been so well said by others that it would be impracticable to make a really new presentation without writing a volume. The Philosophical Society of this city has issued two notices which together cover almost the whole ground that the writer feels competent to occupy. The one is a personal biography—the affectionate and eloquent tribute of an old and attached friend; the other an exhaustive analysis of his scientific labors by an honored member of the society well known for his philosophic acumen.* The Regents of the Smithsonian Institution made known their indebtedness to his administration in the memorial services held in his honor in the Halls of Congress. Under these circumstances the onl}*- practicable course has seemed to be to give a condensed resume of Professor Henry's life and works, by which any small occasional gaps in previous notices might be filled. -

Acquisition sources V. Best editions and preferred formats VI. Collecting levels I. Scope The Collections Policy Statement on Physics and Astronomy covers the subclasses of QB (Astronomy) and QC (Physics), as well as the corresponding subclasses of Class Z. In addition, some of the numerous abstracting and indexing services, catalogs of other scientific libraries, and specialized bibliographic finding aids for these fields are classed in Z. See also the related Collections Policy Statements for Chemical Sciences and Technology. II. Research strengths A. General The Library’s collecting strength in subclasses QB and QC is generally at the research level. The Library has long runs of many important serials such as American Journal of Physics, Journal of Applied Physics, Journal of the British Astronomical Association, and other publications of notable societies and associations, as well as the major abstracting and indexing services in physics and astronomy including Science Abstracts. Series A, Physics Abstracts, and its predecessors, and Astronomischer Jahresbericht and its successor, Astronomy and Astrophysics Abstracts. The Library’s extensive general collections in physics and astronomy are further enhanced by the numerous technical reports held in the Automation, Collections Support & Technical Reports Section, and by specialized materials held by the Manuscript, Rare Book and Special Collections, Geography and Map, and Prints and Photographs Divisions. In addition, the Library’s already extensive collection of U.S. astronomy and physics dissertations in microform is now supplemented by the digital dissertations archive from the ProQuest Dissertations and Theses Global database. -
