Louis-Alphonse Tassin's 1835 doctoral thesis on hygiene practices for pregnant women, for the Faculté de Médecin de Paris: Dissertation sur L'Hygiène des Femmes Enceintes, 17 avril 1835. Written in French. Although merely a doctoral thesis at the Faculty of Medicine in Paris, Tassin's dissertation was listed as far as 55 years later in 1890 in the Index-Catalogue of the Library of the U.S. Surgeon-General's Office (National Library of Medicine, Vol. 11, p. 581).
Most pages are uncut, which means this copy most likely not read, having been kept on file by the faculty after the doctoral degree was achieved. This thin piece is preserved in paper vellum and a light blue paper cover. Measures 11 x 8 3/4 x 1/16 inches. Weighs 1.75 oz.
