were distinguished) . Yu. Kennel replaced him in the depart- 

 ment in 1887, He studied the embryology of Prototracheata 

 and published three works on this topic. 



The true successors of Baer as embryologists were, of 

 course, A, 0. Kovalevsky and I. I. Mechnikov. Not formally 

 students of Baer, they nonetheless paid high tribute to his 

 classical investigations. To Kovalevsky and Mechnikov belong 

 that unquestionable service of further development of Baer's 

 studies and the creation of the theory of embryonic membranes, 

 making the basis for comparative and evolutionary embryology. 



Therefore, it was not by chance that in connection with 

 Baer 1864 jubilee, the Academy of Science established a prize 

 in his name for the best works on biological sciences. The 

 first award of Baer's prize was received by Kovalevsky and 

 Mechnikov. Baer himself participated in the discussion of 

 candidates for the prize and expressed a patriotic pride on 

 the occasion of its being awarded to Russian investigators. 



In the conclusion of this chapter, some words must be 

 stated about Baer as historian of embryology. Although he 

 was not studying systematically the history of embryology, 

 Baer stated many profound ideas about the development of 

 this science. His discussions on this question are scattered 

 through many works. Besides this, Baer subjected the 

 literature of his prominent predecessor in the field of 

 embryology, K. F. Wolff, to special study, and published a 

 report on this work, 36 Baer's research concerning Tredern 

 has been mentioned in Chapter 11. 



References to the history of embryology in the works 

 of Baer are always intimately connected with his own works;
