This is the manuscript of a lecture presented in Houson Hall at the University of Pennsylvania; it was published in "Old Penn," November 21, 1914.

Heavily edited, much of this material was used in his lectures on physiology. The section "Of pleasure: Lect: 20th" (ff. 473-477), corresponds word-for-word with some parts of "Two Lectures upon the Pleasures of the Senses and of the Mind," at the end of his "Sixteen Introductory Lectures" (Philadelphia, 1811).

This was filmed at a lecture Edsall gave in April 1972 in the biochemistry department at Harvard University.

This small collection consists of a series of ten lectures in anthropology given by Robert Redfield (1897-1958, APS 1947) at the University of Chicago and Uppsala University in the summer and fall of 1953. Redfield revised the lectures and printed them two years later in a book titled The Little Community: Viewpoints for the Study of a Human Whole (University of Chicago Press, 1955). The lectures are typed in longhand, with pencil notations.

These papers include correspondence, notes, lectures, articles, and clippings pertaining to scientific matters.

Primary source materials for the history of quantum physics in the twentieth century, collected under the auspices of the APS and the American Physical Society, with a grant from the National Science Foundation. There are transcripts of the oral history interviews, as well as the working papers of the Committee. These include correspondence with famous figures in physics, with some memoirs, photographs, lectures, etc. On microfilm (see Mss. 530.1 Ar2 ) are manuscripts of Niels Henrick David Bohr and his scientific correspondence (62 reels from the Niels Bohr Archives, Universitets Institut for Teoretisk Fysik, Copenhagen). This collection is described and analyzed in Sources for the History of Quantum Physics: An Inventory and Report, by Thomas S. Kuhn, John L. Heilbron, Paul Forman, and Lini Allen (Philadelphia, 1967). The subject guide derived from the work has subsequently been digitized in its entirety and is available through the finding aid for Mss. 530.1 Ar2 .

This is a slide and lecture presentation, prepared by Stephen Kramer, on the Rittenhouse orreries at the University of Pennsylvania and Princeton University. Included is a transcript of the lecture (APS Archives 8/14/81).

This volume contains lecture notes on a variety of topics on Egypt, its natural history in particular (mentioning birds, lizards, and crocodiles), and also hieroglyphics and ancient Egypt.

The Compend of Logick is an interesting illustration of late eighteenth-century American collegiate education. Student Caesar Augustus Rodney penned the work in 1788 frrom a course on logic taught by moral philosophy professor Samuel Magaw. The notebook is a noteworthy manuscript from the early days of an influential university--the University of the State of Pennsylvania--in the hands of a student who would later become an important legal and political figure in the early republic.

These lectures, numbered 1 through 39 and three unnumbered, were delivered at Mr. Peale's Museum and are on such topics as natural history, physical phenomena and the elements, quadrupeds, fishes, birds, primates, and systems of identification. There are notes in the lectures for pauses, music, and illustrations to be included.

The first volume contains mathematical problems, which appear to be college exercises (1814); the second volume is an essay on the projection of the sphere and spherical trigonometry, including an appendix on astronomy (1812); and the third volume is a lecture on natural philosophy, apparently prepared for delivery [n.d.].

These letters and papers include a memorandum book (1795-1827), lectures on botany and medicine, genealogical materials, committee reports from Columbia College, speeches, minutes of the New York Horticultural Society (1822-1828), letters to Sir James Edward Smith (1817-1826), a receipt book of Alexander Hosack (1781-1801), and diaries of Thomas K. Wharton (1830-1862).

This is a collection of Cope's articles, papers, notes, lectures, notebooks, and some correspondence. There is much on his research pertaining to Charles Mason and Jeremiah Dixon, and other topics in the history of science on which he wrote. The collection includes lecture notes and three bound notebook volumes on mechanics from his study at the University of Berlin under Max Planck from 1912 to 1913. There are 11 additional bound volumes, all relating to physics, including: Minutes of meetings of the Department of Physics, University of Pennsylvania (1910-1919), two volumes on the history of physics, and a volume of data on the radiometer as a measurer of electric current. The collection also contains notes on electric circuit theory lectures (1924-1925) by J.R. Carson, notes on lectures on relativity (1921) by Albert Einstein, lectures by W.F.G. Swann (1928), and information about the Pennsylvania Academy of Science, and on radiation (1909). There is significant correspondence from Lionel G. Dixon and Victor Englehardt.

A collection of letters (family and professional), notebooks, diaries, lectures, articles, and photographs, of Smith, a noted American geographer who influenced the teaching of geography after 1920 through his many elementary texts. There is much material relating to these writings. His contributions to the rise of human geography and the related areas of conservation and ecology, are documented. His study in Europe under Friedrich Ratzel, at Leipzig in 1901-1912, is touched on in his journal for those years; included are many interesting observations on German university life. There is also much material on his nursery business in Virginia. Organizational files are numerous, e.g. Association of American Geographers, Columbia University, U. S. Department of Agriculture. Much of the correspondence is limited to only a few letters from each correspondent. Among the names included are: Willard G. Bixby, Isaiah Bowman, John W. Hershey, Emory R. Johnson, Walter C. Lowdermilk (of particular note is his 1926 paper, written while at the University of Nanking, "Forest Conservation in Shansi, China"), and Lewis Mumford.

This is a diverse collection containing professional correspondence, often relating to lectures, speeches, and articles; reprints; and numerous tape recordings.

This collection includes correspondence, manuscripts (lectures and articles), research grant material, research data, and participation in organizations, such as, the American Society of Naturalists (President, 1968), Genetics Society of America (President, 1963), and the National Research Council. Of particular note, are the detailed data related to Drosophila eye pigment, and human chromosomes.

The manuscripts of father William Mitchell and daughter Maria Mitchell are not easily separated, and are treated here together. The collection includes William Mitchell's autobiography, his memoir of Judge Walter Folger of Nantucket, astronomical and meteorological observations, lectures, family and other correspondence.

Robert Maskell Patterson (1787-1854, APS 1809) was a professor of chemistry and natural philosophy at the University of Pennsylvania (1812-1828) and professor of natural philosophy at the University of Virginia (1828-1835). He was director of the U.S. Mint from 1835 to 1851. His father, Robert Patterson, was a revolutionary soldier, professor of mathematics at the University of Pennsylvania (1779-1814), and director of the U.S. Mint (1805-1824).

William Jacob Robbins (1890-1978, APS 1941) was a botanist and physiologist. From 1937 to 1957 he was director of the New York Botanical Garden. His research focused on culture methods of plants in relation to biochemistry and nutrition, especially on the synthetic abilities of fungi. His studies paralleled the scientific agenda of the Rockefeller Foundation, an agency with which he was closely associated for years as adviser and trustee. He was perhaps the most influential botanist in the National Academy of Sciences (NAS) during the early postwar era, and a principal participant in the plans for the global reconstruction of science. Robbins served as president of the American Philosophical Society from 1956 to 1959.
