This is Taylor's dissertation for the degree of Doctor of Medicine from the University of Edinburgh. It was originally published in Latin (Edinburgh, 1800), and John Brandreth made this English translation for a friend in 1830.

In addition to correspondence relating to poultry genetics and egg production, there are significant notes concerning breeding records, heredity, and race genetics. There are 42 class notebooks kept by Goodale, and 62 volumes of Mount Hope Poultry Farm family, hatching, mating records for the period 1918 to 1956. The collection includes photographs, glass-lantern lecture slides, and artifacts of poultry feathers.

Ashley Montagu (1905-1999), physical anthropologist, was a prominent figure in American intellectual life. British by birth, educated at University College London and the London School of Economics, then Columbia University in New York City, Montagu was a persistent advocate for gender and racial equality. He was a tireless activist for human understanding and child welfare in particular. Departing from academe in 1955, a victim of McCarthyite hysteria, he was a remarkably prolific writer and speaker, eventually publishing more than 50 books, over 40 of them after he left the academy. Montagu continued to lobby passionately against the primacy of race in discussions of intellect and skill, and undertook works in a wide variety of fields, from evolution to parenting. Some of his most significant works include Man's Most Dangerous Myth: The Fallacy of Race (1942), the UNESCO Statement on Race (1951), Man and Aggression (1968) and his novel The Elephant Man (1971), which became the basis for an award winning play and movie. Ashley Montagu's contributions to the spread of scientific knowledge and human understanding make him one of the most important intellectuals of the 20th century.

The collection includes three accessions: (1) a portion of Lewontin's correspondence files (mainly A-L) and copies of papers acquired in 1979; (2) a 2003 accession with files on various subjects and correspondence with about 30 colleagues, and (3) a substantial 2018 accession of about 60 linear feet that includes correspondence, manuscripts, and subject files. The topics discussed in the letters are numerous, including much on contemporary scientific controversies such as race, Darwin, evolution, intelligence, and biological determinism.

Founded in 1931, the Genetics Society of America works to facilitate communication among scientists with an interest in research and education in genetics and cognate fields. The GSA Records provide information on the history of the Genetics Society of America from the time of its founding in 1931. Included is correspondence between various officers, members, and outside individuals and organizations, files on standing and ad hoc committees, Records concerning accounts and finances, membership data, files relating to annual meetings, local meetings, and international meetings, and information on special commissions or ad hoc groups of the Society. Among the more noteworthy files are those for the Committee on Genetics, Race, and Intelligence, 1974-1975. This note is currently under review for revision.

Through his craniometic studies of human races, the Philadelphia physician Samuel George Morton (1799-1851) exerted a profound influence on the development of physical anthropology in antebellum America, and made substantial contributions to mineralogy, paleontology, and natural history. Relating primarily to Morton's scientific interests, the Morton Papers include insights into Morton's perspectives on education, medical practice, geology and mineralogy, craniology, paleontology, the Wilkes Exploring Expedition (also known as the United States Exploring Expedition 1838-1842), and his two major monographs, the Crania Americana and Crania Aegyptiaca. Several of the letters were written by Morton in his capacity as corresponding secretary of the Academy of Natural Sciences of Philadelphia. Also included in this collection are Morton's "Some Remarks on the Infrequency of Mixed Offspring Between the European and Australian Races" (1850), Joseph Barclay Pentland's notes on the aborigines of Peru (ca. 1840?), and newspaper clippings on Morton's death; a diary of Morton's trip to the West Indies, 1834, a set of craniological sketches for use in Crania Americana, and a microfilm of letters in private hands, written to Morton, 1838-1844
