CHAPTER 16 



APPEARANCE AND SIGNIFICANCE OF BAER'S MAIN WORK 

 OBER ENTW I CKLUNGSGESCH I CHTE DER THIERE 



There is no doubt that the most remarkable incident in the 

 history of embryology in the first half of the nineteenth century 

 was the appearance of Baer's excellent work, UBER ENTWICKLUNGS- 

 GESCHICHTE DER THIERE, BEOBACHTEN UND REFLEXION. The 

 first volume appeared in 1828; the second volume, not completely 

 edited by the author, appeared in 1837; and the concluding 

 notebook of the second volume was published by L. Steida after 

 Baer's death in 1888. 1 Until recently all three parts of this 

 work represented a bibliographical rarity, because they were 

 never republished and they were not translated completely into 

 Russian. Only in 1924 did a partial translation of part of the 

 first volume appear. 2 in 1950 and 1953, the publishing house 

 of the Academy of Science USSR issued translations of the first 

 and second volumes. 3 



Following the title page of the first volume comes a 

 dedication: "To the friend of my youth, Christian Pander."
