Paris, various publishers, 1884-1886. Nine items in nine (including an original drawing and a manuscript note). 4to and 8vo. Numerous pages and plates. Partly in original wrappers.

Examples of work by the French invertebrate zoologist [Nicolas] Justin Poirier (1849-1912), who specialized in molluscs and worms. The mollusc genus Poirieria Jousseaume was named after him. Included are the following: 1. Contribution a l'histoire des trématodes. 8vo. 160 pp. [numbered 465-624], 12 lithographed plates [numbered XXIII-XXXIV]. Uncut, from the Archive de Zoologie Expérimentale et Générale, Volume III. Without front wrapper; 2. Appareil excréteur et système nerveux duDuthiersia expansa Edm. Perrier, et duSolenophorus megalocephalus Creplin. 4to. 4 pp. Blind blue wrappers. Signed by Poirier, in pencil, above the drophead title "A ma Miette, cocotte chérie et adorée son vilain coquin de gueux. Justin"; 3. (Co-authored with A. T. de Rochebrune) Sur un type nouveau de la classe des Hirudinées. 4to. 4 pp. Blind blue wrappers. Signed by Poirier, in pencil, above the drophead title "A ma bien chère Léontine. Hommage de son bien aimant mari. Justin"; 4. Description d'Helminthes nouveaux du Palonia frontalis. 8vo 7 pp.; one lithographed plate; original blind wrappers. An offprint of the Bulletin de la Société Philomathique de Paris. Séance du 27 janvier 1883. 5. A second copy of the same; 6. A fine pencil drawing (18.0 x 27.5 cm) of a fresh-water mussel, related to, but probably not identical with the European fresh water pearl mussel, Margaritifera margaritifera (L.); 7. an autographed note (bifolium), by Poirier, relative to the reproduction of mushrooms, and to palaeontology, written on stationery of the Faculté des Sciences in Paris; 8. Diplostomidae. Two joint proof plates in lithography with additional colouring, and some corrections in pencil. The plates [numbered XIX and XVIII] were published in the Archive de Zoologie Expérimentale et Générale, Volume IV; 9. Justin Poirier 1849-1912. 8vo. 6 pp.; an undated obituary of Poirier, written by J. Poirier and E. Roubaud. The last item brittle at the edges, due to the low paper quality, with the margins of two leaves creased; all other items very good. Combining examples of Poirier's scientific papers, handwriting, artwork, proofreading, and dedications, this forms a unique ensemble, summarizing his skills, and his importance to zoology.
