(131) Till recently the investigations of Warnek were 

 seriously forgotten. In spite of that, his contemporaries 

 evaluated them highly. It is sufficient to refer to reviews 

 of authors, working on embryology of molluscs (H. Fol. Sur 

 le developpement des Pteropodes. Arch. Zool, exp. gen., 4, 

 1875 and VI. Wolfson, Embryological development of Lymnaeus 

 stagnates . Appendix to the 36th volume of Zap. Peterb. Akad. 

 nauk, 1879, No, 2, 111 pages). About the observations of 

 Warnek, concerning phenomenon of fertilization in mol- 

 luscs, A. D. Nekrasove wrote (fertilization in animal 



kingdom, History of the problem" 1930, pp. 105-106) . In 

 recent years, detailed information about the scientific and 

 teaching activities of Warnek were published by T. P. Platova 

 ("Development of studies on cell in Russia in the 405 to the 

 505 of the 19th century", Fr. In-ta istorii estestvozn., 4, 

 1952, pp, 332-372 and "N. A. Warnek and Moscow University in 

 the middle of the 19th century", here also, 5, 1953, pp. 317- 

 362) (537) . 



(132) "Warnek' s history" found response on the pages of 

 "Kolokol" published by Hertsen, where the following was 

 present "Historical notes, composed by University committee 

 on the occasion of confusions occurred among students of the 

 Moscow University in September 1861". These "notes", or, as 

 these directly called in No, 127 of "Kolokol",— denunciation 

 of Moscow professors— signed by the most reactionary profes- 

 sors — Solovev, Bodyanskii, Leontev, Eshevskii and Chickerij 

 and published as confidential document only in five copies, 

 contains lamentation on inaction of university police and 

 abolition of punishment room, which, according to the authors 

 of "the notes", explains the impunity of the organized student 

 speeches. The clash between the students and professor Warnek, 

 is also mentioned among other analogical events. It is sig- 

 nificant that the authors of "the notes" did not express even 

 by one word their sympathy with the professor who suffered 

 from "excess" of students. This is a personal proof of the 

 unfavorable relation of the reactionary professors to 



Warnek (541) . 



(133) In turn, the colleagues of Krohn, interested in 

 his opinions on their works, demonstrated to him the results 

 of their observations. Thus, the famous Norwegian zoologist 

 M. Sars (1808-1869) , describing the phenomenon of protection
