himself, as he noted this in his "Autobiography", never 

 saw it. In the German language, the classical work of 

 Baer was published in the translation of B. Ottov in 

 1927, in the centennial anniversary of the publication of 

 the Latin original. This work of Baer is still not pub- 

 lished in Russian translation. 



In 1931, the work of Sarton appeared "The discovery 

 of mammalian egg and the foundation of modern embryology", 

 Isis, 16, pp. 15-330, to which the Baer's facsimile "De 

 ovi mammalium et hominis genesi" (pp. 331-377). (Cited in 

 the book, 0. W. Meyer. The rise of embryology, 1939) (286) .

 about the nature of humanity", published in 1820, which in 

 1822 was translated into the Russian language by D. Vellanskii 

 who wrote: "Uterine tubes have in their ends the ovaries, 

 from which the female fertile material raises and conduct 



it to the uterus for mixing with the male semen. The female 

 fertile material, similar to the embryo of the ova-bearing 

 animals, must be located in the Graafian follicles. But 

 these follicles are attached to the ovaries, so they can 

 separate from them with difficulty, and the uterine tubes are 

 narrow for the passage of the follicle. Therefore, I think 

 it explodes, and the fluid present in it passes through the 

 tube to the uterus. May be at the time of copulation the 

 follicle by self-power separates from the ovary, and the 

 tube is widened from conducting it. This is, however, 

 necessary to be proved by more experiments" (§ 352 "About 

 the reproduction and conception of the embryo", p. 543) (288; .

 of anatomy and surgery in London. He published many works 



on anatomy, medical problems as well as physics and chemistry
