Collection of excerpts and notes in Portugese, largely medical and scientific, drawn both from professional publications and from works of more general interest including works of natural history and expedition accounts. The books and journals used as sources are extremely varied: dated throughout the 18th century with a few references to earlier works and many citations to contemporary publications; written in multiple languages, most frequently Latin, French, and English; and published in Paris, Rouen, Amsterdam, Delft, Leiden, London, Edinburgh, Vienna, Madrid, Lisbon, and even in one case in Philadelphia (Transactions of the American Philosophical Society, 1771, p. 1). The manuscript seems to be incomplete, ending with a dangling catchword. A sewn gathering laid in the volume contains two tables of contents, one titled Index auctorum librorumve excerptorum in Adversariorum nostrorum pars I, the other titled Excerptorum memorabilium elenchus. Each table of contents covers the whole volume, neither extending beyond the extant manuscript. Laid in the gathering is a single leaf of rough copies of excerpts from Charles Marie de la Condamine's Journal du voyage fait par ordre du roi à l'équateur that correspond in part to final copies in the manuscript (p. 289). Paper very brittle due to ink oxidation.
