No place, no publisher, no date [but ca. 1900]. 8vo (various sizes). 65 original parts with hundreds of handwritten notes and drawings in black-and-white and in colour. All contained in an original portfolio, size 25 x 20 x 9.5 cm.
This seems to be a manuscript on French algae, being a mostly loose-leaved catalogue of species of Flagellatae, Gelidiaceae, Gigartinaceae, etc., with original observations and literature references (mainly from the late 19th century), all written in a neat and easily readable hand, and with numerous original drawings. Most leaves are stamped "Ex. herb. MALARD", this probably being the French zoologist André Malard, who was assistant manager and "Chef des travaux pratiques" of the Laboratoire Maritime Du Muséum d’Histoire Naturelle de Tatihou, and who is mentioned in Emile Wuitner's Les algues marines de côtes de France: (Manche et Océan)(1921). Edges of the wrappers a bit frayed, otherwise a very good, clean item.
