K. M. Baer said how he, in the spring of 1816, had con- 

 vinced his Dorpat friend Pander to move from Gottingen to 

 l* : iirzburg to work with Dollinger, with whom Baer himself 

 had studied comparative anatomy. Dollinger long cherished 

 a plan to perform a systematic investigation of the 

 chick embryo, but he had neither time nor materials to 

 conclude the work. For this work, a great number of fresh 

 eggs were required. And incubators, because of the lack 

 of thermoregulating facilities, required observation 

 twenty- four hours a day. Further, it was also necessary to 

 invite a graphic artist and an engraver to prepare drawings 

 suitable for reproduction into prints. On a country walk 

 Dollinger, with Baer and Pander, decided that Pander would 

 perform this work and provide the necessary material 

 requirements. 



Here it is appropriate to give some biographical infor- 

 mation about him, however scanty. Khristian Ivanovich Pander 

 was born on May 12,1794 in Riga to the family of a bank 

 director. In 1812 he entered Dorpat University, and from 

 1814 he continued studying medicine in Berlin and Gottingen. 

 In 1816 he worked in WUrzburg with Dollinger. After finish- 

 ing his dissertation in embryology (1817), he worked for 

 about ten years with the artist d 1 Alton in the comparative 

 osteology of contemporary and fossilized animals, and then 

 turned exclusively to paleontological investigations. In 

 1821 Pander was selected a member of Petersburg Academy of 

 Science; he was from 1822 a scientific senior assistant, and 

 then an academician. In 1827 he resigned because "he did not 

 agree with the internal regulations in the Academy and with 

 the leaders of this organization, "4 After that, Pander 

 became an official of special commissions in the scientific 

 section of the mining department. His responsibilities 

 included processing the paleontologic collection brought into 

 the department, which gave him material for his monograph on 

 paleozoic fish. The work of Pander and his contemporary 

 E.I. Eichwald provided the basis of paleontologic studies in 

 Russia. Having, according to his contemporaries,
