Ryazan's students became frightened, and were the cause of 

 their running away from Moscow (183) . 



(51) In the footnote Diadkovskii made a reservation, 

 that he did not want to associate himself with the existing 

 materialistic opinions, obviously, distinctly confessing 



the dissatisfaction of the mechanical materialism. He wrote: 

 "I request not to conclude that I follow, in relation to the 

 opinion about materials, the atomistic or mechanistic system. 

 I accept material as material, as the atomists make this. 

 However, I do not assume any powers inside material, as 

 dyanmists (although I do not want, as it is clear, to regard 

 the material according to their custom, as a phenomenon of 

 power aggregates) . Briefly: for me personally the material 

 is a functioning and searching action". Lebedev has also 

 omitted tendentiously this footnote in his translation. 



Lebedev interpreted the materialistic ideas of his 

 teacher I. E. Diad'kovskii and in the years of scientific 

 and teaching activities (1831-1843) publicized them in his 

 published articles (see for example, article A. V. Lebedev 

 "About life" in "Uchenya Zapiski" of Moscow University, XII, 

 1834) . Ten years later, when successively dismissed from 

 university and Moscow Medico-Surgical Academy, Lebedev did 

 not decide to represent him in censorship without alleviated 

 comments and notes (197) on the publication of the translation 

 of Diad'kovskii's dissertation. 



(52) Oken referred twice to Tredern's dissertation. 



In the discussion of Pander's dissertation ("Isis, No. 192-193, 

 1817), he enumerated the most important investigations of 

 chicken development by Malpighi, Haller, Wolff and Spallantsani 

 Oken continued: "To this must be added the dissertation of 

 Tredern just conducted here. (Why doesn't Tredern give any 

 information about himself?)". One year later Oken published 

 the summary of Dyutrochet's article under the title "Investi- 

 gations of Zh. Kyuve on fetal membranes" ("Isis", 1818, I, 

 pp. 114-126). Dyutrochet wrote the following: "In his 

 thesis about the history of egg and incubation, which he 

 defended in Ien in 1808, Tredern called the allantoic sac 

 the chorion". Oken made .this note about this phrase: "We 

 must notice here that all which was mentioned by Tredern in 

 his dissertation was but a result of his own, and constituted 

 the service he had rendered (210) .
