BAER, Karl Ernst von (1792-1876). ber Entwickelungsgeschichte der Thiere. Beobachtung und Reflexion. [Vol. I-II/1] Knigsberg: Gebrder Borntrger, 1828-1837; [Vol. II/2] Edited by Ludwig Stieda (1837-1918). Knigsberg: Wilhelm Koch, 1888.
2 volumes bound in 3, 4o (237 x 211 mm [vols. I-II/1]; 279 x 228 mm [vol. II/2]). 3 engraved hand-colored plates (2 folding), 4 lithographic plates, folding typographic table, wood-engraved text illustrations. (Clean tear into text of I:Ff2, lithographic plates cropped touching plate number or image, some foxing.) Vol. I-II/1 in contemporary mottled dark green boards, red paper spine labels (some wear), in morocco-backed box; vol. II/2 unopened in original printed wrappers (rebacked, scattered black inkstains), in morocco-backed box.
FIRST EDITION of the "foundation treatise on the embryology of the higher animals" (Grolier/Horblit). "Continuing the work of his friend and collaborator Christian Heinrich Pander [to whom ber Entwickelungsgeschichte der Thiere is dedicated; see lots 1230-1231], Baer observed the formation of the germ layers and established the germ layer theory. He described the way in which the layers formed various organs by tubulation, and he emphasized that the development of the embryo is from the apparently homogeneous to the obviously heterogeneous. In this he finally refuted the long held and much discussed theory that embryonic parts might be preformed in the egg. The publication of this book provided a solid basis for the further systematic study of mammalian development" (Grolier Medicine, p. 215). After the publication of volume I, there was a delay of nearly 10 years while the publisher waited for Baer to complete volume II. In 1837, at the insistence of subscribers to the work, the first part of volume II was published with an explanatory note stating that the author had submitted copy only slowly during the period from 1829 to 1834 and had then ceased to respond to the publisher's inquiries about his progress. The final portion of the text was published only in 1888, after Baer's death, when it was edited by Ludwig Stieda, who also wrote a biography of Baer.
VERY RARE COMPLETE IN THREE VOLUMES. Garrison-Morton 479; Grolier/Horblit 9a; PMM 288b; Wellcome II, p. 84; Norman 101. (3)
