Beschreibung

First edition, 4to, pp. [4], xv, [1], 284, [4]; 17 engraved plates at the back, all composite; contemporary quarter vellum, paste-paper boards, later black leather label lettered in gilt on spine; vellum a little cracked at the spine extremities, edges rubbed and worn, but the binding is sound and the text is clean. In his 1803 treatise Histoire des Conferves d'eau douce, Vaucher (1763-1841), a parish priest turned botanist, described the process of conjugation in certain algae as a distinct sexual process. The phenomena of conjugation is a means of fertilization that takes place in green algae such as Spirogyra. He is credited for describing the development of the networks that occur in the cells of Hydrodictyon (water net algae), and for describing the pyrenoid of algae. The book was reissued in 1830 and again in 4 volumes a few days before his death in 1841. (See Dictionary of Scientific Biography.). Bestandsnummer des Verkäufers 54585
